-‘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.

+The component developer can provide default values for any ``parameter``

+Overridden/Entered Values
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Depending on the other properties set for the parameter, the default
+value can be overridden at ‘design-time’, ‘deploy-time’ or once the
+microservice is running (‘run-time’). (*In the future, when Policy is
+supported, configuration will also be able to be provided/changed in the

+DMaaP connection objects
+========================
+
+DMaaP Connection Objects are JSON objects that:
+
+1. At Runtime - this is generated by the DCAE Platform and passed to the
+ component in its application_configuration to be used to connect to
+ the DMaaP feed or topic. Components will receive the entire object
+ with all properties populated (default will be \`null) unless
+ specified otherwise.
+2. During dcae_cli testing - this is provided through the command-line
+ argument ``--dmaap-file`` to test the component with manually
+ provisioned feeds and topics. Developers are not required to provide
+ the entire object. The required properties are labeled below with
+ “*Required as input*”.

+must minimally contain:
+

+
+ {
+ "type": "data_router",
+ "dmaap_info": {
+ }
+ }
+
+It is the recommended security practice that ``username`` and
+``password`` are specified. You cannot provide the ``delivery_url`` in
+your dmaap-file, because it’s not constructed until deployment time.
+Therefore, after the test deployment, go back to the Data Router Feed
+and provide the delivery_url (in order to start receiving the feeds).
+
+Data Router Example
+~~~~~~~~~~~~~~~~~~~
+
+(After the Data Router feed has been manually provisioned)
+
+::
+
+ $ dcae_cli component run --dmaap-file $dmaap_file $component-name
+ DCAE.Run | WARNING | Your component is a data router subscriber. Here are the delivery urls:
+
+ some-sub-dr: http://135.205.226.128:32838/identity
+
+(Update the Data Router Feed to provide the delivery_url).

-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.

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.
-
-.. _dataformat_metadata:
+Data formats are descriptions of data; they are the data contract
+between your component and other components. When the components are
+‘composed’ into services in the SDC tool, they can only be matched with
+components that have compatible data formats. Data formats will be
+onboarded to SDC and assigned a UUID at that time. This UUID is then
+used to ensure compatibility amoung components. (If component X outputs
+data format ‘DF-Y’, and another component Z specifies ‘DF-Y’ as its
+input data format, then X is said to be ``composable`` with component
+Z).
+
+Since data formats will be shared across components, the onboarding
+catalog should be checked first to see if the desired data format is
+available before creating one. 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. A
+data format is referenced by its data format id and version number.

+JSON schema
+-----------
+
+ The data format specification is represented (and validated) against
+ this `Data Format json schema <https://gerrit.onap.org/r/gitweb?p=dcaegen2/platform/cli.git;a=blob;f=component-json-schemas/data-format/dcae-cli-v1/data-format-schema.json;h=66aa2ab77449e3cafc6afb5c959c5eb793ad86c1;hb=HEAD>`__
+ and described below:
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 ``component`` command is for validating (adding), listing, showing,
+verifying generated configuration, running, undeploying, and publishing
+components that YOU own.
+
+::
+
+ $ dcae_cli component --help

+ undeploy Undeploys the latest version of COMPONENT.
+
+--------------
+
+.. _dcae_cli_add_a_component:
+
+Add a Component
+~~~~~~~~~~~~~~~
+
+A component must be added to the onboarding catalog in order to be
+tested by the dcae_cli tool. The process of adding a component also
+validates it’s component specification. In order to add a component, the
+component docker image (or CDAP jar) must exist locally.
+
+Components in the onboarding catalog can be run by others, once they are
+``published.`` ``Published`` components cannot be modified or deleted.
+Rather a new version can be created instead.
+
+Validated component specs are used later to generate Tosca models and
+Cloudify Blueprints for the component, which makes them available for
+use in the SDC Tool for creating services.
+
+::

+
+--------------
+
+.. _dcae_cli_run_a_component:
+
+Run a Component
+~~~~~~~~~~~~~~~
+
+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. If the
+component uses Dmaap, you can specify the Dmaap Connection Object as
+well. Refer to :doc:`Dmaap Connection Object <../component-specification/dmaap-connection-objects>`.
+
+When you run a component via the dcae_cli Tool, remember the blueprint
+has not been created and is not used for deployment.
+
+In order to run the component, the data formats and component must have
+been added to the onboarding catalog.
+
+**DOCKER NOTE:** Make sure the Docker image has been uploaded to the
+shared registry.
+
+A docker component can be run in either ``attached`` or ``unattached``
+mode. (Default is unattached).
+
++------------------+---------------------------------------------------+
+| Mode | Description |
++==================+===================================================+
+| attached | component is run in the ‘foreground’, container |
+| | logs are streamed to stdout. Ctrl-C is used to |
+| | terminate the dcae_cli session. |
++------------------+---------------------------------------------------+
+| unattached | component is run in the ‘background’, container |
+| | logs are viewed via ``docker logs`` command, |
+| | container runs until undeployed with dcae_cli |
+| | ``undeploy`` command. |

-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*”.

+Create the input file for Dmaap Testing
+---------------------------------------
- Options:
- --help Show this message and exit.
+Currently, the dcae-cli tool does not have the capability to provision
+topics or feeds. Therefore, in order to test with ``message router`` or
+``data router`` feeds, the developer must manually provision the topic
+or feed and then provide the connection details in the form of a DMaap
+JSON file for testing. This file is then passed in on the
+``component run`` or ``component dev`` commands by using the argument
+``--dmaap-file``.
- 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
+The structure of the DMaaP JSON is an object of config keys with the
+topic or feed connection details. The config keys are the ``config_key``
+values specified in the component specification streams section where
+the streams must be type ``message router`` or ``data router``. This
+file corresponds to the ``Dmaap Connection Object`` which is generated
+by the platform and provided to the component at runtime. The exception
+is that ``delivery_url`` cannot be provided in the dmaap-file because it
+is not created until the component is deployed. Refer to :any:`Dmaap Connection Object <dmaap-connection-objects>`, for details on creating the dmaap-file for testing.
-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:
+Create the input file for *Sourced at Deployment* Testing
+---------------------------------------------------------
-::
+Components may have configuration parameters whose values are to be
+sourced at deployment time. This is established in the
+:any:`component specification <common-specification-parameters>`
+by setting the property ``sourced_at_deployment`` to ``true`` for each
+applicable parameter.
- $ dcae_cli profiles list
- rework
- * solutioning
+Then, use the ``--inputs-file`` command-line argument when running the
+component ``dev`` or ``run`` command for your component. This is to
+simulate providing the dynamic, deployment time values for those
+parameters marked as ``sourced_at_deployment``.
-The active profile is ``solutioning`` so to activate *rework* to use

-For Docker containers, you can run either attached or unattached.
-Attached means that the dcae-cli tool will launch the container and not

-
-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:
+A docker component can be run in either ``attached`` or ``unattached``
+mode. (Default is unattached).

-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",
