+Service Discovery
+=================
+
+Service discovery is an architecture pattern used for components
+(micro-services) to locate each other. The DCAE platform uses
+`server-side
+discovery <http://microservices.io/patterns/server-side-discovery.html>`__
+and is using `Consul <https://www.consul.io/>`__ as the service registry
+solution.
+
+Service registration
+--------------------
+
+All components are required to register with Consul in order to be
+discovered. There are two methods of registration: self and 3rd party.
+The DCAE platform uses 3rd party registration which means components
+don’t actually make the registration calls but defers that
+responsibility to a platform service.
+
+Implementation for Docker
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`Registrator <http://gliderlabs.com/registrator/latest/>`__ is an open
+source application that is responsible for registering all components
+that run as Docker containers. Registrator watches the local Docker
+engine’s activity log and will register and unregister a Docker
+container when the container is started and stopped.
+
+Implementation for CDAP
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The CDAP broker is a REST web service that is responsible for
+registering all components that run as CDAP applications.

+‘Services’ Overview
+===================
+
+DCAE Services run on the DCAE platform. A service performs either
+monitors the virtualized network services or does analytics. A service
+is composed of one or more components, and performs a business need.
+
+Services are created in a ‘Service Design and Creation’ tool called
+‘Service Assurance Flow Designer’ by a Service Designer. This is done by
+\* 1. ‘compose’ing a service from the available SDC catalog components
+(actually from the TOSCA models representing the components), then \* 2.
+’submit’ing the service, which generates a Cloudify blueprint, is then
+automatically uploaded to INVENTORY, and then deployed by DEPLOYMENT
+HANDLER (once a DTI Event is triggered for the service). It should be
+noted that some service flows, specifally ’closed-loop’ flows, are not
+initiated by DTI, but are done by CLAMP.

+
+Component specification (CDAP)
+==============================
+
+The CDAP component specification contains the following groups of
+information. Many of these are common to both CDAP and Docker components
+and are therefore described in the common specification.
+
+- :any:`Metadata <metadata>`
+- :any:`Interfaces <interfaces>` including the
+ associated :any:`Data Formats <data-formats>`
+- :any:`Parameters <parameters>` - for specifying parameters in your
+ AppConfig, AppPreferences, and ProgramPreferences to the Designer and
+ Policy. This of course is CDAP-specific and is described below.
+- :any:`Auxiliary Details <auxiliary-details>`
+- :any:`List of artifacts <artifacts>`
+
+Current Limitations and TODOs
+-----------------------------
+
+- The integration of DMD is likely to significantly change the
+ :any:`Interfaces <interfaces>` section in this specification, see
+ :any:`DMaaP abstraction <dmaap-abstraction>`.
+
+.. _parameters:
+
+Parameters
+----------
+
+There is a ``parameters`` section in your component specification. This
+section contains three optional keys: `app_config <#appconfig>`__,
+`app_preferences <#apppreferences>`__, and
+`propram_preferences <#programpreferences>`__:
+
+::
+
+ "parameters" : {
+ "app_config" : [ ...],
+ "app_preferences" : [ ...],
+ "program_preferences" : [...]
+ // any additional keys are ignored
+ }
+
+- Each section details the parameters that are a part of each of these
+ CDAP constructs (see below).
+- All such parameters will be exposed to the designer and to policy for
+ override.
+- These parameters should have default values specified by the
+ component developer where necessary, i.e., parameters that *must*
+ come from the designer/policy should not have defaults.
+- All of these keys are optional because not every CDAP application
+ uses preferences and not every application uses the AppConfig.
+ However, you should specify at least one, or else your application
+ will have no parameters exposed to policy or to the DCAE designer,
+ which means it would be non-configurable.
+- Despite the AppConfig being optional to *specify* in the case that
+ you have no parameters in your AppConfig, it is *required for
+ processing* in your application. That is because the DCAE platform
+ will place important information into your AppConfig as discussed
+ below.
+
+Parameter
+~~~~~~~~~
+
+The following CDAP specific definitions use ``param1`` to refer to the
+common parameter layout in
+:any:`Parameter <parameters>`
+
+AppConfig
+~~~~~~~~~
+
+The ``app_config`` key refers to the `CDAP AppConfig <http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/configuration.html>`_.
+It is expected to be a JSON:
+
+::
+
+ "app_config" : [ // list of JSON
+ param1, // common parameter layout
+ ...
+ ]
+
+Unfortunately, at the time of writing, the AppConfig is a Java map of
+``string:string``, which means you cannot have more complex structures
+(than string) as any value in your AppConfig. However, there is a way to
+bypass this constraint: you can pass a JSON by encoding the JSON as a
+string. E.g., the ``json.dumps()`` and it’s converse ``loads`` methods
+in Python:
+
+::
+
+ >>> import json
+ >>> json.dumps({"foo" : "bar"}) # This is a real JSON
+ '{"foo": "bar"}' # It is now a string: pass this in as your parameter value
+ >>> json.loads('{"foo": "bar"}') # Do the equivelent of this in your application
+ {u'foo': u'bar'} # ...and you'll get back a real JSON
+ >>>
+
+The final AppConfig (after the designer and policy override parameter
+values) is passed into CDAP’s AppConfig API when starting the
+application.
+
+
+AppPreferences
+~~~~~~~~~~~~~~
+
+In addition to the CDAP AppConfig, the platform supports `Application Preferences <http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/preferences.html#set-preferences>`_.
+The format of the ``app_preferences`` value is the same as the above:
+
+::
+
+ "app_preferences" : [ // list of JSON
+ param1, // common parameter layout
+ ...
+ ]
+
+The final Application Preferences JSON (after the designer and policy
+override parameter values) is passed into CDAP’s Preferences API when
+starting your application.
+
+
+ProgramPreferences
+~~~~~~~~~~~~~~~~~~
+
+Preferences can also be specified `per program <http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/lifecycle.html#program-lifecycle>`_
+in CDAP. This key’s value is a list of JSON with the following format:
+
+::
+
+ "program_preferences" : [ // note: this is a list of JSON
+ {
+ "program_id" : "program name 1", // the name of this CDAP program
+ "program_type" : "e.g., flows", // "must be one of flows, mapreduce, schedules, spark, workflows, workers, or services",
+ "program_pref" : [ // list of JSON
+ param1, // common parameter layout
+ ...
+ ]
+ },
+ // repeat for each program that receives a program_preferences JSON
+ ]
+
+Each ``program_pref`` JSON is passed into the CDAP API as the preference
+for ``program_id``.
+
+NOTE: for CDAP, this section is very likely to change when DMD is
+available. The *future* vision, as per :any:`DMaaP intentionally abstracted <dmaap-abstraction>` is
+that you would publish your data as a series of files on HDFS, and DMD
+will pick them up and send them to the appropriate DMaaP feeds or
+directly when needed.
+
+.. _auxiliary-details:
+
+Auxiliary Details
+-----------------
+
+*auxiliary* contains details about CDAP specific parameters.
+
++----------------------+----------------------+----------------------+
+| Property Name | Type | Description |
++======================+======================+======================+
+| streamname | string | *Required*. |
++----------------------+----------------------+----------------------+
+| artifact_name | string | |
++----------------------+----------------------+----------------------+
+| artifact_version | string | the version of your |
+| | | CDAP JAR artifact |
++----------------------+----------------------+----------------------+
+| namespace | string | the CDAP namespace |
+| | | to deploy into, |
+| | | default is ‘default’ |
++----------------------+----------------------+----------------------+
+| programs | array | contains each CDAP |
+| | | entity represented |
+| | | in the artifact |
++----------------------+----------------------+----------------------+
+| program_type | string | CDAP entity (eg |
+| | | “flows”) |
++----------------------+----------------------+----------------------+
+| program_id | string | name of CDAP entity |
+| | | (eg “WhoFlow”) |
++----------------------+----------------------+----------------------+
+
+Example:
+
+.. code:: json
+
+ "auxiliary": {
+ "streamname" : "who",
+ "artifact_name" : "HelloWorld",
+ "artifact_version" : "3.4.3",
+ "namespace" : "hw",
+ "programs" : [
+ {"program_type" : "flows", "program_id" : "WhoFlow"},
+ {"program_type" : "services", "program_id" : "Greeting"},
+ ...
+ ],
+ }
+
+The ``programs`` key is identical to the ``program_preferences`` key
+discussed `above <#programpreferences>`__ except:
+
+- each JSON in the list does not contain ``program_pref``
+- this is required! You must include all of your programs in this, as
+ it is used to start each program as well as for DCAE to perform
+ periodic healthchecks on your application. Don’t forget about your
+ services; they are programs too.

+
+Common Elements of the Component Specification
+==============================================
+
+This page describes the component specification (JSON) sections that are
+common to both Docker and CDAP components. Differences for each are
+pointed out below. Elements that are very different, and described in
+the CDAP or Docker specific pages.
+
+.. _metadata:
+
+Component Metadata
+------------------
+
+Metadata refers to the properties found under the ``self`` JSON. This
+group of properties is used to uniquely identify this component
+specification and identify the component that this specification is used
+to capture.
+
+Example:
+
+::
+
+ "self": {
+ "version": "1.0.0",
+ "name": "asimov.component.kpi_anomaly",
+ "description": "Classifies VNF KPI data as anomalous",
+ "component_type": "docker"
+ },
+
+``self`` Schema:
+
++-------------+--------+----------------+

+| | | name of |
+| | | this |

+| | | used as |
+| | | this |
+| | | component's |
+| | | catalog |
+| | | id. |
++-------------+--------+----------------+
+| description | string | *Required* |
+| | | Human-readable |
+| | | text |
+| | | describing |
+| | | the |
+| | | component |
+| | | and the |
+| | | components |
+| | | functional |

+| | | t |
+| | | uses: |
+| | | *docker* |
+| | | or |
+| | | *cdap*. |
+| | | |
++-------------+--------+----------------+
+
+.. _interfaces:
+
+Interfaces
+----------
+
+Interfaces are the JSON objects found under the ``streams`` key and the
+``services`` key. These are used to describe the interfaces that the
+component uses and the interfaces that the component provides. The
+description of each interface includes the associated :any:`data
+format <data-formats>`.
+
+Streams
+~~~~~~~
+
+- The ``streams`` JSON is for specifying data produced for consumption
+ by other components, and the streams expected to subscribe to that is
+ produced by other components. These are “fire and forget” type
+ interfaces where the publisher of a stream does not expect or parse a
+ response from the subscriber.
+- The term ``stream`` here is abstract and neither refers to “CDAP
+ streams” or “DMaaP feeds”. While a stream is very likely a DMaaP
+ feed, it could be a direct stream of data being routed via HTTP too.
+ It abstractly refers to a sequence of data leaving a publisher.
+- Streams have anonymous publish/subscribe semantics, which decouples
+ the production of information from its consumption.
+- In general, components are not aware of who they are communicating
+ with.
+- Instead, components that are interested in data, subscribe to the
+ relevant stream; components that generate data publish to the
+ relevant stream.
+- There can be multiple publishers and subscribers to a stream. Streams
+ are intended for unidirectional, streaming communication.
+
+Streams interfaces that implement an HTTP endpoint must support POST.
+
+Streams are split into:

+ "version": "1.0.0",
+ "route": "/data", // for CDAP this value is not used
+ "type": "http"
+ }],
+ ...
+ }
+
+This describes that ``asimov.component.kpi_anomaly`` exposes an HTTP
+endpoint called ``/data`` which accepts requests that have the data
+format of ``dcae.vnf.kpi`` version ``1.0.0``.

+Message router
+''''''''''''''
+
+Message router subscribers are http clients rather than http services
+and performs a http a ``GET`` call. Thus, message router subscribers
+description is structured like message router publishers and requires
+``config_key``:
+
+.. code:: json
+
+ "streams": {
+ "subscribes": [{
+ "format": "dcae.some-format",
+ "version": "1.0.0",

+ "type": "message router"
+ }],
+ ...
+ }
+
+
+.. _data-router:
+
+Data router
+'''''''''''
+
+Data router subscribers are http or https services that handle ``PUT``
+requests from data router. Developers must provide the ``route`` or url
+path/endpoint that is expected to handle data router requests. This will
+be used to construct the delivery url needed to register the subscriber
+to the provisioned feed. Developers must also provide a ``config_key``
+because there is dynamic configuration information associated with the
+feed that the application will need e.g. username and password. See the
+page on :doc:`DMaaP connection objects <../dcae-cli/dmaap-connection-objects>` for more details on
+the configuration information.
+
+Example (not tied to the larger example):
+
+.. code:: json
+

+Quick Reference
+^^^^^^^^^^^^^^^
+
+Refer to this :doc:`Quick Reference <streams-grid>` for a
+comparison of the Streams ‘Publishes’ and ‘Subscribes’ sections.
+
+Services
+~~~~~~~~
+
+- The publish / subscribe model is a very flexible communication
+ paradigm, but its many-to-many one-way transport is not appropriate
+ for RPC request / reply interactions, which are often required in a
+ distributed system.
+- Request / reply is done via a Service, which is defined by a pair of
+ messages: one for the request and one for the reply.
+
+Services are split into:
+
++-------------+----+----------+
+| Property | Ty\| Descript\|

+| | | t |
+| | | exposes |
+| | | and |
+| | | provides |
++-------------+----+----------+
+
+Calls
+^^^^^
+
+The JSON ``services/calls`` is for specifying that the component relies
+on an HTTP(S) service—the component sends that service an HTTP request,
+and that service responds with an HTTP reply. An example of this is how
+string matching (SM) depends on the AAI Broker. SM performs a
+synchronous REST call to the AAI broker, providing it the VMNAME of the
+VNF, and the AAI Broker responds with additional details about the VNF.
+This dependency is expressed via ``services/calls``. In contrast, the
+output of string matching (the alerts it computes) is sent directly to
+policy as a fire-and-forget interface, so that is an example of a
+``stream``.
+
+Example:
+
+.. code:: json
+
+ "services": {
+ "calls": [{
+ "config_key": "vnf-db",
+ "request": {
+ "format": "dcae.vnf.meta",
+ "version": "1.0.0"
+ },
+ "response": {
+ "format": "dcae.vnf.kpi",
+ "version": "1.0.0"
+ }
+ }],
+ ...
+ }
+
+This describes that ``asimov.component.kpi_anomaly`` will make HTTP
+calls to a downstream component that accepts requests of data format
+``dcae.vnf.meta`` version ``1.0.0`` and is expecting the response to be
+``dcae.vnf.kpi`` version ``1.0.0``.

+Example:
+
+.. code:: json
+
+ "services": {
+ ...
+ "provides": [{
+ "route": "/score-vnf",
+ "request": {
+ "format": "dcae.vnf.meta",

+ },
+ "response": {
+ "format": "asimov.format.integerClassification",
+ "version": "1.0.0"
+ }
+ }]
+ },
+
+This describes that ``asimov.component.kpi_anomaly`` provides a service
+interface and it is exposed on the ``/score-vnf`` HTTP endpoint. The
+endpoint accepts requests that have the data format ``dcae.vnf.meta``
+version ``1.0.0`` and gives back a response of
+``asimov.format.integerClassification`` version ``1.0.0``.

+Component specification (Docker)
+================================
+
+The Docker component specification contains the following groups of
+information. Many of these are common to both Docker and CDAP components
+and are therefore described in the common specification.
+
+- :any:`Metadata <metadata>`
+- :any:`Interfaces <interfaces>` including the
+ associated :any:`Data Formats <data-formats>`
+- :any:`Parameters <parameters>`
+- :any:`Auxiliary Details <docker-auxiliary-details>`
+- :any:`List of Artifacts <artifacts>`

+Health Check Definition
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The platform uses Consul to perform periodic health check calls. Consul
+provides different types of `check definitions <https://www.consul.io/docs/agent/checks.html>`_. The
+platform currently supports http and docker health checks.
+
+When choosing a value for interval, consider that too frequent
+healthchecks will put unnecessary load on Consul and DCAE. If there is a
+problematic resource, then more frequent healthchecks are warranted (eg
+15s or 60s), but as stablility increases, so can these values, (eg
+300s).
+
+When choosing a value for timeout, consider that too small a number will
+result in increasing timeout failures, and too large a number will
+result in a delay in the notification of resource problem. A suggestion
+is to start with 5s and workd from there.

+| | | to be |
+| | | executed |
++-------------+----+------------+
+
+Consul will use the `Docker exec API <https://docs.docker.com/engine/api/v1.29/#tag/Exec>`_ to
+periodically call your script in your container. It will examine the
+script result to identify whether your component is healthy. Your
+component is considered healthy when the script returns ``0`` otherwise
+your component is considered not healthy.
+
+Example:
+
+.. code:: json
+
+ "auxilary": {
+ "healthcheck": {
+ "type": "docker",
+ "script": "/app/resources/check_health.py",
+ "timeout": "30s",
+ "interval": "180s"
+ }
+ }
+
+Ports
+~~~~~
+
+.. code:: json
+
+ "auxilary": {
+ "ports": ["8080:8000"]
+ }
+
+In the example above, container port 8080 maps to host port 8000.
+
+Volume Mapping
+~~~~~~~~~~~~~~
+
+.. code:: json
+
+ "auxilary": {
+ "volumes": [
+ {
+ "container": {
+ "bind": "/tmp/docker.sock",
+ "mode": "ro"
+ },
+ "host": {
+ "path": "/var/run/docker.sock"
+ }
+ }
+ ]
+ }
+
+At the top-level:
+
++---------------+-------+-------------------------------------+
+| Property Name | Type | Description |
++===============+=======+=====================================+
+| volumes | array | Contains container and host objects |
++---------------+-------+-------------------------------------+
+
+The ``container`` object contains:
+
++----------------------+----------------------+----------------------+
+| Property Name | Type | Description |
++======================+======================+======================+
+| bind | string | path to the |
+| | | container volume |
++----------------------+----------------------+----------------------+
+| mode | string | “ro” - indicates |
+| | | read-only volume |
+| | | “” - indicates that |
+| | | the container can |
+| | | write into the bind |
+| | | mount |
++----------------------+----------------------+----------------------+
+
+The ``host`` object contains:
+
++---------------+--------+-------------------------+
+| Property Name | Type | Description |
++===============+========+=========================+
+| path | string | path to the host volume |
++---------------+--------+-------------------------+
+
+Here’s an example of the minimal JSON that must be provided as an input:
+
+.. code:: json
+
+ "auxilary": {
+ "volumes": [
+ {
+ "container": {
+ "bind": "/tmp/docker.sock"
+ },
+ "host": {
+ "path": "/var/run/docker.sock"
+ }
+ }
+ ]
+ }
+
+In the example above, the container volume “/tmp/docker.sock” maps to
+host volume “/var/run/docker.sock”.
+
+Policy
+~~~~~~
+
+Policy changes made in the Policy UI will be provided to the Docker
+component by triggering a script that is defined here.

+
+Generated configuration
+=======================
+
+The DCAE platform relies on the component specification to generate the
+component’s application configuration JSON at deployment time. The
+component developer should expect to use this configuration JSON in
+their application to provision themselves.
+
+Pro-tip: As you build your component specification, you can use the
+:any:`dcae-cli dev command <walkthrough-dev>` to view what
+the resulting application configuration will look like.
+
+Streams and services
+--------------------
+
+For both Docker and CDAP, when your component is deployed, any
+``streams`` and ``services/calls`` you specified will be injected into
+your configuration under the following well known structure. Your
+component is required to parse this information if you have any
+connectivity to DMaaP or are calling another DCAE component.
+
+More details about the DMaaP connection objects are found
+:doc:`here <../dcae-cli/dmaap-connection-objects>`.
+
+This is best served with an example.
+
+The following component spec snippet (from String Matching):
+
+::
+
+ "streams":{
+ "subscribes": [{
+ "format": "VES_specification",
+ "version": "4.27.2",
+ "type": "message_router",
+ "config_key" : "mr_input"
+ }],
+ "publishes": [{
+ "format": "VES_specification",
+ "version": "4.27.2",
+ "config_key": "mr_output",
+ "type": "message_router"
+ }]
+ },
+ "services":{
+ "calls": [{
+ "config_key" : "aai_broker_handle",
+ "verb": "GET",
+ "request": {
+ "format": "get_with_query_params",
+ "version": "1.0.0"
+ },
+ "response": {
+ "format": "aai_broker_response",
+ "version": "3.0.0"
+ }
+ }],
+ "provides": []
+ },
+
+Will turn into the following top level keys in your configuration (for
+CDAP, this will be under AppConfig)
+
+::
+
+ "streams_publishes":{
+ "mr_output":{ // notice the config key above
+ "aaf_password":"XXX",
+ "type":"message_router",
+ "dmaap_info":{
+ "client_role": null,
+ "client_id": null,
+ "location": null,
+ "topic_url":"XXX"
+ },
+ "aaf_username":"XXX"
+ }
+ },
+ "streams_subscribes":{
+ "mr_input":{ // notice the config key above
+ "aaf_password":"XXX",
+ "type":"message_router",
+ "dmaap_info":{
+ "client_role": null,
+ "client_id": null,
+ "location": null,
+ "topic_url":"XXX"
+ },
+ "aaf_username":"XXX"
+ }
+ },
+ "services_calls":{
+ "aai_broker_handle":[ // notice the config key above
+ "SOME_IP:32768" // based on deployment time, just an example
+ ]
+ }
+
+These keys will always be populated regardless of whether they are
+empty. So the minimal you will get, in the case of a component that
+provides an HTTP service and does not call any services and has no
+streams, is:
+
+::
+
+ "streams_publishes":{},
+ "streams_subscribes":{},
+ "services_calls":{}
+
+Thus your component should expect these well-known top level keys.

+Streams Formatting Quick Reference
+==================================
+
+Each of the following tables represents an example of a publisher and
+its subscriber, which are of course, different components. This focuses
+on the fields that are ‘different’ for each of these TYPEs, to
+illustrate the relationship between ``config_key``, dmaap connection
+object, and the generated configuration. Some notes on specific
+properties:
+
+- ``config_key`` is an arbitrary string, chosen by the component
+ developer. It is returned in the generated configuration where it
+ contains specific values for the target connection
+- ``format``, ``version``, and ``type`` properties in the subscriber
+ would match these properties in the publisher
+- ``aaf_username`` and ``aaf_password`` may be different between the
+ publisher and the subscriber

+
+CDAP Component Requirements
+===========================
+
+This page contains information about CDAP app development in DCAE.
+
+Uploading your Jar File
+-----------------------
+
+The DCAE component specification has you input your ``jar_url``, the URL
+on Nexus to your Jar file. This DCAE controller deploys out of Nexus.
+You can upload your jar(s) using the following command, replacing NAME:
+
+::
+
+ curl -v --user 'user:password' http://YOUR_NEXUS_RAW_REPO/NAME.jar --upload-file NAME.jar
+
+During the CLI Tool Usage, in your spec, supply
+``http://YOUR_NEXUS_RAW_REPO/NAME.jar`` as the JAR artifact URL.
+
+Policy Reconfiguration
+----------------------
+
+We support reconfiguration of both AppConfig and AppPreferences.
+
+For AppConfig, we support CDAPs “update” API to `reconfigure an application <http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/lifecycle.html#update-an-application%7D%7D>`_.
+
+For AppPreferences, we:
+
+1. Stop your programs
+
+2. Set the new preferences
+
+3. Start your programs
+
+At the time of writing, there is no way to update a CDAP application’s
+AppConfig or AppPreferences, without a restart, *and notify* the
+application. The latter is a future promised feature by CASK—the ability
+to update preferences and inform the application that something is
+changed (so it repulls). As CDAP currently stands however, given the
+above, if you are building a stateful application, you must persist your
+state often (e.g., to a CDAP dataset), as you may be restarted at any
+time with an updated configuration, or stopped&started at any time with
+updated preferences.
+
+Metrics
+-------
+
+Metrics are pulled from your CDAP application on a periodic basis and
+(in the future: pushed to a central DCAE metric store, currently: just
+dropped). For this to be useful, your application should provide `metrics <http://docs.cask.co/cdap/current/en/admin-manual/operations/metrics.html>`_.
+While nothing in the DCAE runtime enforces that your CDAP application
+tracks metrics, your metrics (or lack thereof) will be visible in the
+DCAE dashboard and to operations.
+
+.. _dmaap-abstraction:
+
+Future DMaaP abstraction
+------------------------
+
+Shown below is our *vision* for how DMaaP is abstracted from component
+developers:
+
+.. figure:: ../images/dmdvision.png
+ :alt: Screenshot
+
+ Screenshot
+
+Today, this is a vision; it is not in place. Today, each CDAP app is
+built with built in assumptions about where they are getting their data
+from. Some CDAP apps have the built in assumption of a UEB feed. Some
+MR. Some DR. This becomes very difficult to orchestrate when each app in
+the catalog has built in data assumptions.
+
+The goal of this vision is to *decouple* the data plane from the
+analytics plane. Analytics should be agnostic to *how* they are
+receiving their data beyond “filesystem” or “HTTP”. Analytics developers
+shouldn’t have to worry about the data plane, that should be taken care
+of by the platform. They should be spending their time on the problem at
+hand—the analytic.
+
+This also allows each CDAP application to have a standard set of
+interfaces: HTTP and HDFS: |Screenshot|

+
+Docker Component Requirements
+=============================
+
+Overview
+--------
+
+Component developers are required to provide artifacts for the platform
+to be able to deploy your component including:
+
+- :any:`Component specification <docker-specification>`
+- :doc:`Data formats <data-formats>`
+- :any:`Auxiliary component specification <docker-auxiliary-details>`
+- :any:`Docker image <docker-on-the-platform>`
+
+In addition, components will have to be enhanced to be compliant with
+the DCAE platform in order to correctly be deployed and be managed. This
+page will discuss the changes which are grouped into the following
+categories:
+
+- :any:`Service registration <service-registration>`
+- :any:`Configuration management on the new platform <docker-configuration>`
+- :any:`Operational concerns <operational-concerns>`
+
+To help component developers to make and to test the changes needed to
+have components run on the platform, a command-line tool called
+:doc:`dcae-cli <dcae-cli/quickstart>` is provided by the platform team.
+
+.. _service-registration:
+
+Service registration
+--------------------
+
+Every :doc:`Docker component is registered <architecture/service-discovery>` with the platform’s
+service discovery layer. Docker components are not expected to make the
+explicit make registration calls because that is done by through a
+platform 3rd party registration service. A couple things are needed from
+component developers in order for this registration to occur
+successfully:
+
+1. Docker images must be created from a Dockerfile that has an `EXPOSE <https://docs.docker.com/engine/reference/builder/#/expose>`_ instruction. This applies to components that listen on a port.
+2. Component healthcheck details must be provided in the Docker
+ auxiliary component specification
+
+Expose port
+~~~~~~~~~~~
+
+Components that listen on a specific port must explicitly declare in
+their Dockerfile that port using the ``EXPOSE`` instruction before
+building the image. Warning! At the current time, you can not expose
+multiple ports in your Dockerfile or registration *will not work*
+correctly.
+
+Health check
+~~~~~~~~~~~~
+
+Component developers are required to provide a way for the platform to periodically check the health of their running components. The platform uses Consul to perform these periodic calls. Consul provides different types of `check definitions <https://www.consul.io/docs/agent/checks.html>`_. The details of the definition used by your component is to be provided through the :any:`Docker auxiliary specification <docker-auxiliary-details>`.
+
+.. _docker-configuration:
+
+Configuration
+-------------
+
+The component’s application configuration is generated from the
+submitted component specification into a JSON representation. The DCAE
+platform will provide the configuration JSON by making it available on a
+remote HTTP service. Components are required to pull their configuration
+JSON at application startup. The configuration JSON is stored under the
+components uniquely generated name which is provided by the environment
+variable ``HOSTNAME``.
+
+You can see more details on the generated application configuration
+:any:`here <docker-specification>`.
+
+Config binding service
+~~~~~~~~~~~~~~~~~~~~~~
+
+The config binding service is a platform HTTP service that is
+responsible for providing clients with a fully resolved configuration
+JSON at runtime. Components should make an HTTP GET on:
+
+::
+
+ <config binding service hostname>:<port>/service_component/NAME
+
+For Docker components, NAME should be set to ``HOSTNAME``, which was
+provided as an ENV variable inside of your container.
+
+The binding service integrates with the streams and services section of
+your component specification. For example, if you specify that you call
+a service:
+
+::
+
+ "services": {
+ "calls": [{
+ "config_key": "vnf-db",
+ "request": {
+ "format": "dcae.vnf.meta",
+ "version": "1.0.0"
+ },
+ "response": {
+ "format": "dcae.vnf.kpi",
+ "version": "1.0.0"
+ }
+ }],
+ ...
+ }
+
+Then the config binding service will find all available IP addresses of
+services meeting your needs, and provide them to you under your
+``config_key``:
+
+::
+
+ // your configuration
+ {
+ "vbf-db" : // see above
+ [IP:Port1, IP:Port2,…] // all of these meet your needs, choose one.
+ }
+
+Regarding ``<config binding service hostname>:<port>``, there is DNS
+work going on to make this resolvable in a convenient way inside of your
+container. However, currently you will be given a name as an ENV
+variable, ``CONFIG_BINDING_SERVICE``, and you will need to query
+Consul’s service discovery to get
+``<config binding service hostname>:<port>``.
+
+Policy Reconfiguration
+~~~~~~~~~~~~~~~~~~~~~~
+
+*(Draft and subject to change)*
+
+Components must provide a way to receive policy reconfiguration, that
+is, configuration parameters that have been updated via the Policy UI.
+The component developer provides a docker script (defined in the :any:`Docker auxiliary specification <docker-specification>`)
+that will be triggered when this occurs.
+
+DMaaP
+~~~~~
+
+Components can be publishers or subscribers to either message router
+topics or data router feeds. This is defined in the component
+specification under the ``streams`` section where you can specify
+whether your component is expected to subscribe or to publish to a
+:any:`message router topic <message-router>` or to a :any:`data router feed <data-router>`.
+Given a composition with components that use DMaaP, the platform will
+provision the topic or feed and provide the necessary :any:`connection details <dcae-cli/dmaap-connection-objects>` at runtime for each DMaaP
+dependent component. These connection details will be provided through
+your application’s :any:`generated configuration <component-specification/generated-configuration>`.
+
+In order to test DMaaP connections in onboarding, the developer
+(currently) must provision all test topics and feeds manually and
+provide the :any:`dcae-cli with the connection details <dmaap-testing>` when deploying your
+application.
+
+.. _docker-on-the-platform:
+
+Docker on the platform
+----------------------
+
+Images
+~~~~~~
+
+Docker images must be pushed to the environment specific Nexus
+repository. This requires tagging your build with the full name of you
+image which includes the Nexus repository name.
+
+Use the Docker command-line to `tag <https://docs.docker.com/engine/reference/commandline/tag/>`_ your Docker image where the *target image* must contain the registry host name and port.
+
+For example, an application called laika has been tagged for an example
+Nexus registry:
+
+::
+
+ $ docker images
+ REPOSITORY TAG IMAGE ID CREATED SIZE
+ YOUR_NEXUS_DOCKER_REGISTRY/laika 0.4.0 154cc382df61 7 weeks ago 710.5 MB
+ laika 0.4.0 154cc382df61 7 weeks ago 710.5 MB
+
+Note, the Docker registry that is used may require a login to
+authenticate.
+
+::
+
+ docker login YOUR_NEXUS_DOCKER_REGISTRY
+
+Tag your image:
+
+::
+
+ docker tag laika:0.4.0 YOUR_NEXUS_DOCKER_REGISTRY/laika:0.4.0
+
+Or build and tag:
+
+::
+
+ docker build -t YOUR_NEXUS_DOCKER_REGISTRY/laika:0.4.0 .
+
+After tagging, upload your image to the remote registry using the Docker `push command <https://docs.docker.com/engine/reference/commandline/push/>`_ .
+Note that the registry may require a login. Use the Docker `login command <https://docs.docker.com/engine/reference/commandline/login/>`_
+before pushing in that case.
+
+::
+
+ docker push YOUR_NEXUS_DOCKER_REGISTRY/laika:0.4.0
+
+*NOTE* Replace ``laika`` with your application’s name. Replace the
+``0.4.0`` version with your application’s version.
+
+Ports
+~~~~~
+
+On the DCAE platform, Docker components are run with the ``--publish-all`` or ``-P`` argument. This means the Docker container
+for your component will be listening on a random port and that random
+port will be mapped to the port :any:`you exposed <service-registration>`.
+
+Envs
+~~~~
+
+The platform provides a set of environment variables into each Docker
+container:
+
++----------------------------+----+----------+
+| Na\ | Ty\| Descript\|
+| me | pe | ion |
++============================+====+==========+
+| ``HOSTNAME`` | st\| Unique |

+
+Operational concerns
+--------------------
+
+Logging
+~~~~~~~
+
+Currently the platform uses the default ``json-file`` logging driver for
+Docker. For onboarding testing, component developers can access their
+logs from their Docker containers either by running their component
+using the ``--attached`` flag or by using the ``docker logs`` command.
+The requirement is that applications must write to stdout and/or stderr.
+
+To use the ``docker logs`` command for your deployed running Docker
+container,
+
+1. You must have Docker installed on your local machine
+2. Have the generated name of your component. This is generated for you
+ when you execute ``dcae_cli component dev`` or
+ ``dcae_cli component run``.
+3. Find the target Docker host using the ``dcae_cli profiles show``
+ command:
+
+::
+
+ $ dcae_cli profiles show YOUR_PROFILE_NAME
+ {
+ ...
+ "docker_host": "YOUR_DOCKER_HOST:2376"
+ }
+
+4. Set your Docker client to point to the target Docker host:
+
+::
+
+ $ export DOCKER_HOST="tcp://YOUR_DOCKER_HOST:2376"
+
+5. Use the ``docker logs`` command:
+
+::
+
+ $ docker logs <generated component name>

+
+Data Formats
+============
+
+| Because the DCAE designer composes your component with others at
+ service design time, in most cases you do not know what specific
+ component(s) your component will send data to during runtime. Thus, it
+ is vital that DCAE has a language of describing the data passed
+ between components, so that it is known which components are
+ composable with others. Data formats are descriptions of data—they are
+ the data contract between your component and other components. You
+ need to describe the available outputs and assumed inputs of your
+ components as data formats. These data descriptions are onboarded into
+ ASDC, and each receives a UUID. If component X outputs data format
+ DF-Y, and another component Z specifies DF-Y as their input data
+ format, then X is said to be *composable* with that component. The
+ data formats are referenced in the component specifications by the
+ data format’s id and version.
+| The vision is to have a repository of shared data formats that
+ developers and teams can re-use and also provide them the means to
+ extend and create new custom data formats.
+

+
+Meta Schema Definition
+----------------------
+
+The “Meta Schema” implementation defines how data format JSON schemas
+can be written to define user input. It is itself a JSON schema (thus it
+is a “meta schema”). It requires the name of the data format entry, the
+data format entry version and allows a description under “self” object.
+The meta schema version must be specified as the value of the
+“dataformatversion” key. Then the input schema itself is described.
+There are four types of schema descriptions objects - jsonschema for
+inline standard JSON Schema definitions of JSON inputs, delimitedschema
+for delimited data input using a defined JSON description, unstructured
+for unstructured text, and reference that allows a pointer to another
+artifact for a schema. The reference allows for XML schema, but can be
+used as a pointer to JSON, Delimited Format, and Unstructured schemas as
+well.
+
+The current Meta Schema implementation is defined below:
+
+::

+Examples
+-----------
+
+By reference example - Common Event Format
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First the full JSON schema description of the Common Event Format would
+be loaded with a name of “Common Event Format” and the current version
+of “25.0.0”.
+
+Then the data format description is loaded by this schema:
+
+::
+
+ {
+ "self": {
+ "name": "Common Event Format Definition",
+ "version": "25.0.0",
+ "description": "Common Event Format Definition"

+DMaaP connection objects
+========================
+
+DMaaP connection objects are JSON objects that:
+
+1. Components should expect at runtime in their application
+ configuration and is to be used to connect to the appropriate DMaaP
+ feed or topic.
+2. Developers must provide through the command-line argument
+ ``--dmaap-file`` to test their component with manually provisioned
+ feeds and topics.
+
+This page is a reference to the specific structure that each type of
+DMaaP stream requires.
+
+Note for #1 that components should expect the entire object with all
+properties at runtime where the default will be ``null`` unless
+specified otherwise.
+
+Note for #2 that developers are not required to provide the entire
+object. The required properties will be labeled with “*required as
+input*”.

+deploying the component since this can only be known at deployment time.

+Quickstart
+==========
+
+The ``dcae-cli`` is a Python command-line tool built to aide component
+developers with the development and testing of their micro-service
+component for the DCAE platform. It will help developers do functional
+and integration testing of their components locally and on remote
+environments as simple as possible.
+
+The tool requires the component developers to create a valid component
+specification for their component which is used by the tool. This same
+component specification will be published in the :any:`onboarding catalog <glossary-onboarding-catalog>` at the end of development
+and testing.
+
+.. The git repository can be found `here <ONAP%20LINK%20TBD>`__
+
+Pre-requisite
+-------------
+
+For Docker
+~~~~~~~~~~
+
+There are two options for development with Docker: developing locally on
+your machine which requires Docker to be installed and developing
+remotely by deploying onto remote infrastructure.
+
+For local development
+^^^^^^^^^^^^^^^^^^^^^
+
+- You must install `Docker
+ engine <https://docs.docker.com/engine/installation/>`__ locally on
+ your machine.
+- You must know the *external ip* of where the Docker engine is
+ running. The external ip is needed so that service discovery will
+ wire up correctly.
+
+ - For OSX users, this means making sure the VirtualBox VM that is
+ running your Docker engine has a bridged adapter and getting the
+ ip of that adapter.
+
+For remote development
+^^^^^^^^^^^^^^^^^^^^^^
+
+You need access to a remote host with Docker engine installed with
+remote API access. You must have the associated connection information:
+domain name or IP and port (should be either 2375 or 2376). This
+information should be set in :any:`an active profile <setting-profile>`.
+
+For CDAP
+~~~~~~~~
+
+TBD
+
+Install
+-------
+
+::
+
+ pip install --extra-index-url https://YOUR_NEXUS_PYPI_SERVER/simple dcae-cli
+
+To do an upgrade, use the ``--upgrade`` flag.
+
+Configuration
+~~~~~~~~~~~~~
+
+When you run the tool for the first time, the tool will create a
+`configuration
+directory <http://click.pocoo.org/5/api/#click.get_app_dir>`__ and
+generate a configuration file.
+
+Configuration is first sourced from an remote server that the platform
+team manages. This is overlaid with configuration details that you will
+be prompted to input particularly your user id.
+
+``--reinit``
+^^^^^^^^^^^^
+
+Configuration can be re-initialized or reset. There is a ``--reinit``
+flag that is to be used to re-initialize your configuration and your
+environment profiles.
+
+To re-initialize:
+
+::
+
+ $ dcae_cli --reinit
+
+Verify
+~~~~~~
+
+Verify that its installed:
+
+::
+
+ $ dcae_cli --help
+ Usage: dcae_cli [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ -v, --verbose Prints INFO-level logs to screen.
+ --reinit Re-initialize dcae-cli configuration
+ --version Show the version and exit.
+ --help Show this message and exit.
+
+ Commands:
+ catalog
+ component
+ data_format
+ profiles
+
+Version
+-------
+
+You can verify the version of the dcae-cli with the following command:
+
+::
+
+ $ dcae_cli --version

+.. _walkthrough:
+
+Walk-through
+============
+
+The goal of this quickstart is to provide an overview of the
+functionalities of the ``dcae-cli`` and walk you through the
+capabilities:
+
+- `Adding data formats <#adding-data-formats>`__
+- `Adding component <#adding-component>`__
+- `Setting profile <#setting-profile>`__
+- `Development and testing <#development-and-testing>`__
+- `Publishing component <#publishing-component>`__
+- `Shared catalog <#shared-catalog>`__
+
+.. This walk-through uses example projects: COMMENTED OUT FOR NOW TBD
+..
+.. - `laika <ONAP%20URL%20TBD>`__
+.. - `CDAP examples <ONAP%20URL%20TBD>`__
+
+.. _adding-data-formats:
+
+Adding data formats
+-------------------
+
+``data_format`` is the sub-command that is used to execute operations
+that manage `data formats <../data-formats.md>`__.
+
+::
+
+ $ dcae_cli data_format --help
+ Usage: dcae_cli data_format [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ --help Show this message and exit.
+
+ Commands:
+ add Tracks a data format file SPECIFICATION...
+ generate Generates a data format file from JSON input examples
+ list Lists all your data formats
+ publish Publishes data format to make publicly...
+ show Provides more information about FORMAT
+
+Your data format must be in the catalog in order to use in the component
+specification. Check the catalog using the ``data_format list``
+sub-command:
+
+::
+
+ $ dcae_cli data_format list
+
+ Data formats for mh677g
+ +------+---------+-------------+--------+----------+
+ | Name | Version | Description | Status | Modified |
+ +------+---------+-------------+--------+----------+
+ | | | | | |
+ +------+---------+-------------+--------+----------+
+
+The fields ``name``, ``version``, ``description`` are referenced from
+the data format JSON from the ``self`` JSON.
+
+There are no data formats so you must add the data formats that your
+component specification references. Use the ``data_format add``
+sub-command:
+
+Here’s an example command:
+
+::
+
+ dcae_cli data_format add health.json
+
+Verify that it was added:
+
+::
+
+ $ dcae_cli data_format list
+
+ Data formats for mh677g
+ +-------------------------------+---------+-------------------------------------------+--------+----------------------------+
+ | Name | Version | Description | Status | Modified |
+ +-------------------------------+---------+-------------------------------------------+--------+----------------------------+
+ | sandbox.platform.laika.health | 0.1.0 | Data format used for the /health endpoint | staged | 2017-05-23 04:02:38.952799 |
+ +-------------------------------+---------+-------------------------------------------+--------+----------------------------+
+
+Go ahead and add other referenced data formats.
+
+If you have JSON input you can generate a data format like this:
+
+::
+
+ $ dcae_cli data_format --keywords generate myname:1.0.0 myjsoninputfile
+
+where ``myname`` is the name of your data format, ``1.0.0`` is an
+example version, and ``myjsoninputfile`` is an example JSON input file
+(a directory of input JSON files can also be provided). The
+``--keywords`` option adds additional data attributes that can be
+completed to provide a more detailed data characterization. In any event
+the output should be reviewed for accuracy. The data format is written
+to stdout.
+
+.. _adding-component:
+
+Adding component
+----------------
+
+``component`` is the sub-command that is used to work with operations
+for components:
+
+::
+
+ $ dcae_cli component --help
+ Usage: dcae_cli component [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ --help Show this message and exit.
+
+ Commands:
+ add
+ dev Set up component in development for...
+ list Lists components in the public catalog.
+ publish Pushes COMPONENT to the public catalog
+ run Runs the latest version of COMPONENT.
+ show Provides more information about COMPONENT
+ undeploy Undeploys the latest version of COMPONENT.
+
+Your component must be accessible from the catalog in order for it to be
+used. Check the catalog using the ``component list`` sub-command:
+
+::
+
+ $ dcae_cli component list
+ Active profile: solutioning
+
+ +------+---------+------+-------------+--------+----------+-----------+
+ | Name | Version | Type | Description | Status | Modified | #Deployed |
+ +------+---------+------+-------------+--------+----------+-----------+
+ | | | | | | | |
+ +------+---------+------+-------------+--------+----------+-----------+
+
+ Use the "--deployed" option to see more details on deployments
+
+The fields ``name``, ``version``, ``type``, ``description`` are
+referenced from the component specification’s ``self`` JSON.
+
+There are no components so you must add your component. Use the
+``component add`` sub-command. The command is the same for docker and
+cdap components:
+
+::
+
+ $ dcae_cli component add --help
+ Usage: dcae_cli component add [OPTIONS] SPECIFICATION
+
+ Options:
+ --update Updates a locally added component if it has not been already
+ pushed
+ --help Show this message and exit.
+
+*Note* use the ``--update`` flag to replace existing staged instances.
+
+The ``component dev`` sub-command can be useful in validating and
+experimenting when crafting your component specification. See details
+about ``dev`` under `Development and
+testing <#development-and-testing>`__.
+
+Once we add the components laika and helloworld, let’s verify that they
+got added ok:
+
+::
+
+ $ dcae_cli component list
+ Active profile: solutioning
+
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+ | Name | Version | Type | Description | Status | Modified | #Deployed |
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+ | cdap.helloworld.endnode | 0.8.0 | cdap | cdap test component | staged | 2017-05-23 04:14:35.588075 | 0 |
+ | sandbox.platform.laika | 0.5.0 | docker | Web service used as a stand-alone test DCAE service compone.. | staged | 2017-05-23 04:07:44.065610 | 0 |
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+
+ Use the "--deployed" option to see more details on deployments
+
+.. _setting-profile:
+
+Setting profile
+---------------
+
+``profile`` is the sub-command that is used to manage profiles. These
+profiles contain environment variables used to connect to different
+environments. This is used in the running and deployment of your
+component using the ``dcae_cli component run`` command. The ``dcae-cli``
+ships with profiles for ``solutioning`` and ``rework``.
+
+::
+
+ $ dcae_cli profiles --help
+ Usage: dcae_cli profiles [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ --help Show this message and exit.
+
+ Commands:
+ activate Sets profile NAME as the active profile
+ create Creates a new profile NAME initialized with...
+ delete Deletes profile NAME
+ list Lists available profiles
+ set Updates profile NAME such that KEY=VALUE
+ show Prints the profile dictionary
+
+To see what variables a profile contains, you can use the ``show``
+command, as in ``dcae_cli profiles show PROFILE_NAME``
+
+Use the ``create`` sub-command to create your own profile and assign new
+values using the ``set`` command. Afterwards you will need to
+``activate`` the profile you wish to use. First take a look at which
+profile is active:
+
+::
+
+ $ dcae_cli profiles list
+ rework
+ * solutioning
+
+The active profile is ``solutioning`` so to activate *rework* to use
+``rework``:
+
+::
+
+ $ dcae_cli profiles activate rework
+
+Check
+
+::
+
+ $ dcae_cli profiles list
+ * rework
+ solutioning
+
+.. _development-and-testing:
+
+Development and testing
+-----------------------
+
+The following operations under the sub-command ``component`` are aimed
+to help developers with testing:
+
+- ``run``
+- ``undeploy``
+- ``dev``
+
+``run``
+~~~~~~~
+
+The ``run`` operation is to be used for running your application in its
+container remotely on the activated environment. Docker containers have
+the additional option to run locally on your development machine.
+
+In order to run your application, you must have added your data formats
+and your component to your catalog.
+
+Let’s verify that your component is in the catalog:
+
+::
+
+ $ dcae_cli component list
+ Active profile: solutioning
+
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+ | Name | Version | Type | Description | Status | Modified | #Deployed |
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+ | cdap.helloworld.endnode | 0.8.0 | cdap | cdap test component | staged | 2017-05-23 04:14:35.588075 | 0 |
+ | sandbox.platform.laika | 0.5.0 | docker | Web service used as a stand-alone test DCAE service compone.. | staged | 2017-05-23 04:07:44.065610 | 0 |
+ +-------------------------+---------+--------+---------------------------------------------------------------+--------+----------------------------+-----------+
+
+ Use the "--deployed" option to see more details on deployments
+
+Docker
+^^^^^^
+
+**NOTE** Make sure your Docker image has been uploaded to the shared
+registry.
+
+For Docker containers, you can run either attached or unattached.
+Attached means that the dcae-cli tool will launch the container and not
+terminate. The dcae-cli while attached will stream in the logs of the
+Docker container. Doing a Ctrl-C will terminate the run session which
+means undeploy your container and force a clean up automatically.
+
+Running unattached means simply deploy your container. You will need to
+execute ``undeploy`` when you are done testing. #### CDAP
+
+**NOTE** Make sure your CDAP jar has been uploaded to Nexus.
+
+TODO
+
+``undeploy``
+~~~~~~~~~~~~
+
+The ``undeploy`` operation is to be used to undeploy any instances of a
+specified component, version that you have deployed. This includes
+cleaning up of configuration.
+
+Let’s undeploy ``sandbox.platform.laika`` that was deployed from the
+previous section:
+
+::
+
+ $ dcae_cli component undeploy sandbox.platform.laika:0.5.0
+ DCAE.Undeploy | WARNING | Undeploying components: 1
+ DCAE.Undeploy | WARNING | Undeployed components: 1
+
+.. _walkthrough-dev:
+
+``dev``
+~~~~~~~
+
+The ``dev`` operation is a convenient operation that can be useful for
+the development and testing of your component. It can be used to:
+
+- Help validate your experimental component specification before
+ uploading to the catalog
+- Generate the application configuration from the component
+ specification and make it available in a test environment. This
+ allows you to view your resulting configuration for local development
+ and to help debug potential related issues.
+
+Let’s say you have a component specification called
+``component-spec.json``:
+
+::
+
+ $ dcae_cli component dev component-spec.json
+ Ready for component development
+
+ Setup these environment varibles. Run "source env_solutioning":
+
+ export DOCKER_HOST=SOME_DOCKER_HOST:2376
+ export SERVICE_CHECK_INTERVAL=15s
+ export CONFIG_BINDING_SERVICE=config_binding_service
+ export HOSTNAME=mh677g.95740959-63d2-492a-b964-62a6dce2591d.0-6-0.sandbox-platform-laika
+ export CONSUL_HOST=SOME_CONSUL_HOST
+ export CDAP_BROKER=cdap_broker
+ export SERVICE_NAME=mh677g.95740959-63d2-492a-b964-62a6dce2591d.0-6-0.sandbox-platform-laika
+ export SERVICE_CHECK_TIMEOUT=1s
+ export SERVICE_CHECK_HTTP=/health
+
+ Press any key to stop and to clean up
+
+Your application configuration is now available under the name
+``mh677g.95740959-63d2-492a-b964-62a6dce2591d.0-6-0.sandbox-platform-laika``.
+
+To view the resulting configuration, you can ``curl`` a request to the
+config binding service or programmatically fetch your configuration
+within your application.
+
+You need to first query Consul to get the ip and port of config binding
+service:
+
+::
+
+ curl http://$CONSUL_HOST:8500/v1/catalog/service/$CONFIG_BINDING_SERVICE
+ [
+ {
+ "ID": "983d5c94-c508-4a8a-9be3-5912bd09786b",
+ "Node": "realsolcnsl00",
+ "Address": "10.226.1.22",
+ "TaggedAddresses": {
+ "lan": "10.226.1.22",
+ "wan": "10.226.1.22"
+ },
+ "NodeMeta": {},
+ "ServiceID": "5f371f295c90:config_binding_service:10000",
+ "ServiceName": "config_binding_service",
+ "ServiceTags": [],
+ "ServiceAddress": "XXXX",
+ "ServicePort": 32770,
+ "ServiceEnableTagOverride": false,
+ "CreateIndex": 487,
+ "ModifyIndex": 487
+ }
+ ]
+
+.. _dmaap-testing:
+
+DMaaP testing
+~~~~~~~~~~~~~
+
+Currently, the dcae-cli does not have the capability of provisioning
+topics. In order to do testing with message router topics or with data
+router feeds, the developer must provision the topic or the feed
+manually and provide the connection details in the form of a JSON in a
+file to the dcae-cli. This file is to be passed in when using the
+``run`` and ``dev`` commands with the option ``--dmaap-file``.
+
+The structure of the DMaaP JSON is an object of config keys to matching
+topic or feed connection details. Config keys are the ``config_key``
+values specified in your component specification streams section where
+the streams must be type message router or data router. Information
+about the associated connection details can be found on `this
+page <dmaap-connection-objects.md>`__. Please check it out.
+
+For example, if you have a component specification that has the
+following streams entry:
+
+.. code:: json
+
+ "streams": {
+ "publishes": [{
+ "format": "ves",
+ "version": "1.0.0",
+ "type": "message router",
+ "config_key": "ves_connection"
+ }]
+ }
+
+Then to deploy and to run your component, you must use the
+``--dmaap-file`` command and pass in a JSON that looks like:
+
+.. code:: json
+
+ {
+ "ves_connection": {
+ "type": "message_router",
+ "dmaap_info": {
+ "topic_url": "https://we-are-message-router.us:3905/events/some-topic"
+ }
+ }
+ }
+
+The provided DMaaP JSON is used to simulate the output of provisioning
+and will be used to merge with the generated application configuration
+at runtime.
+
+Your final application config will look like:
+
+.. code:: json
+
+ {
+ "streams_publishes": {
+ "ves_connection": {
+ "type": "message_router",
+ "dmaap_info": {
+ "topic_url": "https://we-are-message-router.us:3905/events/some-topic"
+ }
+ }
+ }
+ }
+
+Data router subscribers
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Note for data router subscriber testing, you will need the delivery url
+in order to provision the subscriber to the feed. This is constructed at
+deployment time and will be provided by the dcae-cli after you deploy
+your component. The delivery urls will be displayed to the screen:
+
+::
+
+ DCAE.Run | WARNING | Your component is a data router subscriber. Here are the delivery urls:
+
+ some-sub-dr: http://SOME_IP:32838/identity
+
+*Sourced at deployment* testing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Components may have configuration parameters whose values are to be
+sourced at deployment time. For example, there are components whose
+configuration parameters are to come from DTI events which are only
+available when the component is getting deployed. These configuration
+parameters must be setup correctly in the `component
+specification <http://localhost:8000/components/component-specification/docker-specification/#configuration-parameters>`__
+by setting the property ``sourced_at_deployment`` to ``true`` for each
+and every parameter that is expected to come in at deployment time.
+
+Once your component specification has been updated correctly, you must
+use the ``--inputs-file`` command-line argument when running the
+commands ``dev`` or ``run`` with your component. This is to simulate
+providing the dynamic, deployment time values for those parameters
+marked as ``sourced_at_deployment``.
+
+For example, if your component specification has the following
+configuration parameters:
+
+::
+
+ "parameters": [{
+ "name": "vnf-ip",
+ "value": "",
+ "sourced_at_deployment": true
+ },
+ {
+ "name": "static-param",
+ "value": 5
+ }]
+
+You would have to pass in an inputs file that looks like:
+
+::
+
+ {
+ "vnf-ip": "10.100.1.100"
+ }
+
+Your application configuration would look like:
+
+::
+
+ {
+ "vnf-ip": "10.100.1.100",
+ "static-param": 5
+ }
+
+Publishing component
+--------------------
+
+Once components have their component specifications crafted and
+validated and have been tested, components should be published in the
+shared onboarding catalog using the ``publish`` sub-command for both
+data formats and components. You must publish all data formats of a
+component before publishing a component.
+
+Publishing will change the status of a component, be made accessible for
+other developers to use, and will generate the associated TOSCA models
+for use in designing of compositions.
+
+::
+
+ dcae_cli component publish sandbox.platform.laika:0.5.0
+
+Shared catalog
+--------------
+
+``catalog`` is the sub-command used to access and to browse the shared
+onboarding catalog to view components and data formats that have been
+published and that are being worked on. Components and data formats have
+two statuses ``staged`` and ``published``.
+
+Staged means that the resource has been simply added and is under
+development. It is to be used only by the owner. Published means that
+the resource has been fully developed and tested and is ready to be
+shared.
+
+Published components can be deployed by non-owners and published data
+formats can be used in component specifications of non-owners.
+
+There are two available operations:
+
+::
+
+ $ dcae_cli catalog --help
+ Usage: dcae_cli catalog [OPTIONS] COMMAND [ARGS]...
+
+ Options:
+ --help Show this message and exit.
+
+ Commands:
+ list
+ show
+
+Staged components can be viewed under the ``list`` operation using the
+``--expanded`` flag.

+
+Component Developer Overview
+============================
+
+DCAE components are services that provide a specific functionality and
+are written to be composable with other DCAE service components. The
+DCAE platform is responsible for running and managing DCAE service
+components reliably.
+
+Currently, the DCAE platform supports two types of components, CDAP
+applications and Docker containers. For each, there are requirements
+that must be met for the component to integrate into the DCAE platform
+(see :doc:`CDAP <component-type-cdap>` and :doc:`Docker <component-type-docker>`.
+
+Components requires one or more data formats.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Components are software applications that do some function. Components
+don’t run independently, they depend upon other components. A
+component’s function could require connecting to other components to
+fulfill that function. A component could also be providing its function
+as a service through an interface for other components to use.
+
+Components cannot connect to or be connected with any other component.
+The upstream and downstream components must *speak* the same vocabulary
+or *data format*. The output of an one component must match another
+component’s input. This is necessary for components to function
+correctly and without errors.
+
+The platform requires data formats to ensure that a component will be
+run with other *compatible* components.
+
+Data formats can and should be shared by multiple components.
+
+Each Component requires a component specification.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The component specification is a JSON artifact that fully specifies the
+component, it’s interfaces, and configuration. It’s standardized for
+CDAP and Docker applications and is validated using a :any:`JSON
+schema <dcae-component-schema>`.
+
+The component specification fully specifies all the configuration
+parameters of the component. This is used by the designer and by policy
+(future) to configure the runtime behavior of the component.
+
+The component specification is used to *generate* application
+configuration in a standardized JSON that the platform will make
+available to the component. This application configuration JSON will
+include:
+
+- Parameters that have been assigned values from the component
+ specification, policy, and/or the designer
+- Connection details of downstream components
+
+The component specification is transformed by DCAE tooling (explained
+later) into TOSCA models (one for the component, and in the future, one
+for Policy). The TOSCA models then get transformed into Cloudify
+blueprints.
+
+The component specification is used by:
+
+- dcae_cli tool - to validate it
+- Design Tools - TOSCA models are generated from the component
+ specification so that the component can be used by designers to
+ compose new DCAE services in SDC.
+- Policy (future) - TOSCA models are generated from the component
+ specification so that operations can create policy models used to
+ dynamically configure the component.
+- the runtime platform - The component’s application configuration
+ (JSON) is generated from the component specification and will be
+ provided to the component at runtime.
+
+Onboarding
+----------
+
+Onboarding is a process that ensures that the component is compliant
+with the DCAE platform rules. A command-line tool called :doc:`dcae-cli <dcae-cli/quickstart>` is provided to help with onboarding. The high level summary of the onboarding process is:
+
+1. Defining the :doc:`data formats <data-formats>` if they don’t already
+ exist.
+2. Define the :doc:`component specification <component-specification/common-specification>`. See :doc:`Docker <component-specification/docker-specification>` and :doc:`CDAP <component-specification/cdap-specification>`.
+3. Use the dcae_cli tool to :any:`add the data formats <adding-data-formats>`
+ and :any:`add the component <adding-component>` to
+ the onboarding catalog. This process will validate them as well.
