Nodes of this type are place in a blueprint + so that they can be set up to "bridge" to other feed nodes of type + ``ccsdk.nodes.Feed`` or ``ccsdk.nodes.ExistingFeed``. This type has + no node properties, but when a bridge is set up, the url, username, + and password are attached to the node as runtime\_properties, using + the name of the target feed node as the top-level key. + +There are five relationship types for DMaaP Data Router: + +- ``ccsdk.relationships.publish_files``, used to indicate that the + relationship's source node sends is a publisher to the Data Router + feed represented by the relationship's target node. +- ``ccsdk.relationships.subscribe_to_files``, used to indicate that the + relationship's source node is a subscriber to the Data Router feed + represented by the relationship's target node. +- ``ccsdk.relationships.bridges_to``, used to indicate that the + relationship's source node (a ``ccsdk.nodes.Feed`` or + ``ccsdk.nodes.ExistingFeed``) should be set up to forward data + ("bridge") to the relationship's target feed (another + ``ccsdk.nodes.Feed`` or ``ccsdk.nodes.ExistingFeed``). +- ``ccsdk.relationships.bridges_to_external``, used to indicate that + the relationship's source node (a ``ccsdk.nodes.Feed`` or + ``ccsdk.nodes.ExistingFeed``) should be set up to forward data + ("bridge") to the relationship's target node (a feed in an external + DMaaP system, represented by a ``ccsdk.nodes.ExternalTargetFeed`` + node). +- ``ccsdk.relationships.bridges_from_external_to_internal``, used to + indicate the the relationship's source node (a feed in an external + DMaaP system, represented by a ``ccsdk.nodes.ExternalSourceFeed`` + node) should be set up to forward date ("bridge") to the + relationship's target node (an internal ONAP feed, represented by a + ``ccsdk.nodes.Feed`` or ``ccsdk.nodes.ExistingFeed`` node). + +The plugin code implements the lifecycle operations needed to create and +delete feeds and to add and remove publishers and subscribers. It also +implements the operations needed to set up bridging between feeds. + +Interaction with Other Plugins +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +When creating a new feed or processing a reference to an existing feed, +the plugin operates independently of other plugins. + +When processing a ``ccsdk.relationships.publish_files`` relationship or +a ``ccsdk.relationships.subscribe_to_files`` relationship, this plugin +needs to obtain data from the source node and, in the case of +``publish_files``, provide data to the source node. Certain conventions +are therefore needed for passing data between this plugin and the +plugins responsible for the source nodes in these relationships. In +Cloudify, the mechanism for sharing data among plugins is the +``ctx.instance.runtime_properties`` dictionary associated with each +node. + +A given source node may have relationships with several feeds. For +example, an ONAP DCAE data collector might publish two different types +of data to two different feeds. An ONAP DCAE analytics module might +subscribe to one feed to get input for its processing and publish its +results to a different feed. When this DMaaP plugin and the plugin for +the source node exchange information, they need to do in a way that lets +them distinguish among different feeds. We do this through a simple +convention: for each source node to feed relationship, the source node +plugin will create a property in the source node's +``runtime_properties`` dictionary. The name of the property will be the +same as the name of the target node of the relationship. For instance, +if a node has a ``publishes_files`` relationship with a target node +named ``feed00``, then the plugin that's responsible for managing the +source node with create an entry in the source node's +``runtime_properties`` dictionary named ``feed00``. This entry itself +will be a dictionary. + +The content of this data exchange dictionary depends on whether the +source node is a publisher (i.e., the relationship is ``publish_files``) +or a subscriber (i.e., the relationship is ``subscribe_to_files``). + +For the ``publish_files`` relationship, the data exchange dictionary has +the following properties: + ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ +| Property | Set by | Description | ++================+======================+==================================================================================================+ +| location | source node plugin | the DMaaP location for the publisher, used to set up routing | ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ +| publish\_url | DMaaP plugin | the URL to which the publisher makes Data Router publish requests | ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ +| log\_url | DMaaP plugin | the URL from which log data for the feed can be obtained | ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ +| username | DMaaP plugin | the username (generated by the DMaaP plugin) the publisher uses to authenticate to Data Router | ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ +| password | DMaaP plugin | the password (generated by the DMaaP plugin) the publisher uses to authenticate to Data Router | ++----------------+----------------------+--------------------------------------------------------------------------------------------------+ + +For the ``subscribe_to_files`` relationship, the data exchange +dictionary has the following properties: + ++-----------------+----------------------+-----------------------------------------------------------------------------------------+ +| Property | Set by | Description | ++=================+======================+=========================================================================================+ +| location | source node plugin | the DMaaP location for the subscriber, used to set up routing | ++-----------------+----------------------+-----------------------------------------------------------------------------------------+ +| delivery\_url | source node plugin | the URL to which the Data Router should deliver files | ++-----------------+----------------------+-----------------------------------------------------------------------------------------+ +| username | source node plugin | the username Data Router uses to authenticate to the subscriber when delivering files | ++-----------------+----------------------+-----------------------------------------------------------------------------------------+ +| password | source node plugin | the username Data Router uses to authenticate to the subscriber when delivering file | ++-----------------+----------------------+-----------------------------------------------------------------------------------------+ + +Plugin Support for DMaaP Message Router +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Plugin Types for DMaaP Message Router +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The Cloudify type definitions for DMaaP Message Router nodes and +relationships are defined in ```dmaap.yaml`` <./dmaap.yaml>`__. + +There are two node types for DMaaP Message Router: + +- ``ccsdk.nodes.Topic``: This type represents a topic that does not yet + exist and that should be created when the install workflow is run + against a blueprint that contains a node of this type. + ++----------------------+-----------+-------------+-----------------------------------------------------------------------------+ +| Property | Type | Required?

Here are a couple of pieces of +information that might be helpful. Currently, the allowed values for +``replication_case`` are: + +- ``REPLICATION_NONE`` +- ``REPLICATION_EDGE_TO_CENTRAL`` +- ``REPLICATION_EDGE_TO_CENTRAL_TO_GLOBAL`` +- ``REPLICATION_CENTRAL_TO_EDGE`` +- ``REPLICATION_CENTRAL_TO_GLOBAL`` +- ``REPLICATION_GLOBAL_TO_CENTRAL`` +- ``REPLICATION_GLOBAL_TO_CENTRAL_TO_EDGE`` + +The ``global_mr_url`` is actually a host name, not a full URL. It points +to a host in a global message router cluster. (A 'global' message router +cluster is one that's not part of ONAP.) + +- ``ccsdk.nodes.ExistingTopic``: This type represents a topic that + already exists. Nodes of this type are placed in a blueprint so that + other nodes in the blueprint can be set up as publishers or + subscribers to the topic. The table below shows the properties that a + node of this type may have. + ++------------+----------+-------------+--------------------------------------------+ +| Property | Type | Required? | Description | ++============+==========+=============+============================================+ +| fqtn | string | yes | fully-qualified topic name for the topic | ++------------+----------+-------------+--------------------------------------------+ + +Interaction with Other Plugins +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +When creating a new topic or processing a reference to an existing +topic, the plugin operates independently of other plugins. + +When processing a ``ccsdk.relationships.publish_events`` relationship or +a ``ccsdk.relationships.subscribe_to_events`` relationship, this plugin +needs to obtain data from and provide data to the source node. Certain +conventions are therefore needed for passing data between this plugin +and the plugins responsible for the source nodes in these relationships. +In Cloudify, the mechanism for sharing data among plugins is the +``ctx.instance.runtime_properties`` dictionary associated with each +node. + +A given source node may have relationships with several topics. For +example, an ONAP DCAE analytics module might subscribe to one topic to +get input for its processing and publish its results to a different +topic. When this DMaaP plugin and the plugin for the source node +exchange information, they need to do in a way that lets them +distinguish among different feeds.

For instance, +if a node has a ``publishes_events`` relationship with a target node +named ``topic00``, then the plugin that's responsible for managing the +source node with create an entry in the source node's +``runtime_properties`` dictionary named ``topic00``.

This allows DMaaP clients (components +that act as publishers, subscribers, or both) to retrieve their DMaaP +configuration information from Consul, rather than having the plugin +that deploys the client directly configure the client using data in +``runtime_properties``. + +The ``runtime_properties`` for a client must contain a property called +``service_component_name``. If this property is not present, the plugin +will raise a NonRecoverableError and cause the installation to fail. + +If ``service_component_name`` is present, then the plugin will use a +Consul key consisting of the value of ``service_component_name`` +prepended to the fixed string ``:dmaap``. For example, if the +``service_component_name`` is ``client123``, the plugin will use +``client123:dmaap`` as the key for storing DMaaP information into +Consul. Information for all of the feeds and topics for a client are +stored under the same key. + +The value stored is a nested JSON object. At the top level of the object +are properties representing each topic or feed for which the component +is a publisher or subscriber. The name of the property is the node name +of the target feed or topic. The value of the property is another JSON +object that corresponds to the dictionary that the plugin created in +``runtime_properties`` corresponding to the target feed or topic. Note +that the information in Consul includes all of the properties for the +feed or topic, those set by the source node plugin as well as those set +by the DMaaP plugin. + +Examples: + +Data Router publisher, target feed ``feed00``: + +:: + + { + "feed00": { + "username": "rC9QR51I", + "log_url": "https://dmaap.example.com/feedlog/972", + "publish_url": "https://dmaap.example.com/publish/972", + "location": "loc00", + "password": "QOQeUh5KLR", + "publisher_id": "972.360gm" + } + } + +Data Router subscriber, target feed ``feed01``: + +:: + + { + "feed01": { + "username": "drdeliver", + "password": "1loveDataR0uter", + "location": "loc00", + "delivery_url": "https://example.com/whatever", + "subscriber_id": "1550" + } + } + +Message Router publisher to ``topic00``, subscriber to ``topic01``. Note +how each topic appears as a top-level property in the object. + +:: + + { + "topic00": { + "topic_url": "https://dmaap.example.com:3905/events/org.onap.ccsdk.dmaap.FTL2.outboundx", + "client_role": "org.onap.ccsdk.member", + "location": "loc00", + "client_id": "1494621774522" + }, + "topic01": { + "topic_url": "https://dmaap.example.com:3905/events/org.onap.ccsdk.dmaap.FTL2.inboundx", + "client_role": "org.onap.ccsdk.member", + "location": "loc00", + "client_id": "1494621778627" + } + } + +Packaging and installing +~~~~~~~~~~~~~~~~~~~~~~~~ + +The DMaaP plugin is meant to be used as a `Cloudify managed +plugin `__. +Managed plugins are packaged using +```wagon`` `__. + +To package this plugin, executing the following command in the top-level +directory of this plugin, from a Python environment in which ``wagon`` +has been installed: + +:: + + wagon create -s . -r -o /path/to/directory/for/wagon/output + +Once the wagon file is built, it can be uploaded to a Cloudify Manager +host using the ``cfy plugins upload`` command described in the +documentation above. + +Managed plugins can also be loaded at the time a Cloudify Manager host +is installed, via the installation blueprint and inputs file. We expect +that this plugin will be loaded at Cloudify Manager installation time, +and that ``cfy plugins upload`` will be used only for delivering patches +between releases. + +Configuration +~~~~~~~~~~~~~ + +The plugin needs to be configured with certain parameters needed to +access the DMaaP Bus Controller. In keeping with the ONAP architecture, +this information is stored in Consul. + +The plugin finds the address and port of the DMaaP Bus Controller using +the Consul service discovery facility. The plugin expects the Bus +Controller to be registered under the name ``dmaap_bus_controller``. + +Additional parameters come from the ``dmaap`` key in the Cloudify +Manager's Consul configuration, which is stored in the Consul KV store +under the key name 'cloudify\_manager'.
