This page describes how to get the Istanbul release version of A1-Policy functions up and running using Docker.

...

Note: Version numbers used in this page may not be the most recent ... you should verify the latest version numbers for released pre-built components in the docker image repository (https://nexus3.onap.org)

Project Requirements

• Java 11 (make sure that JAVA_HOME environment variable points to correct Java version)

• Maven 3.6 (make sure you have configured maven to access the ONAP maven repositories)
  

• Docker and docker-compose (latest)

Create Configuration for A1 Policy Management Service

Configure the A1 Policy Management Service

To support local test with four separate near-RT-RIC simulator instances:  

• Copy the default configuration file oran/a1-policy-management/config/application_configuration.json (london) to the current directory, then replace/amend the configuration with the sample demo configuration below.
  (Note the configuration below is just a sample, and should be updated to match particular deployments.  The deployment below assumes 4 near-RT-RICs exist - addressable at the URLs given. See the step "Run OSC Near-RT-RIC/A1 Simulator Docker Containers" below)

• The controller URL (hostname, port), username and password values to access the A1 Controller (SDNC + A1 Adapter) must match the values configured for the SDNC-A1-Controller. (See the step "Run A1 Controller" further below). The port number for http is 8181.
  (Note the configuration below is just a sample, and should be updated to match particular deployments.  The deployment below assumes an A1 Controller function (SDNC) exists - addressable at the url given, using the authentication credentials given.)

• Any defined ric host names (in the name and baseUrl for each ric entry) must match the given docker container names in near-RT-RIC simulator startup - port is always the simulator's internal port 8085 for http or 8185 for https.

• The A1 Policy Management service can entirely by-pass the A1-Controller (SDNC + A1 Adapter) if desired - it is optional to access the near-RT-RIC through an A1-Controller.
  

  Info
  title Alternative: Bypass the A1-Controller - connect direct from A1-Policy Management Service
  There is no functional gain in accessing the near-RT-RIC through an A1-Controller. To bypass the  A1-Controller (SDNC + A1 Adapter), where the A1-Policy Management Service connects directly to the A1 Interface: In the configuration the "controller" property is optional in the "ric" objects If all configured rics bypass the A1-Controller (do not have "controller" values) then the "controller" object at the top of the configuration can be omitted. If all configured rics bypass the A1-Controller there is no need to start an A1-Controller.

JSON Schema for the application configuration

The configuration must comply to the following JSON schema. There are several publicly available tools (e.g. online) where it is possible to validate JSON objects against their schema. 
The schema is available in the gerrit repo (application_configuration_schema.json (london))

Run OSC Near-RT-RIC/A1 Simulator Docker Containers

• Start docker containers for each near-RT-RIC defined in oran/a1-policy-management/config/application_configuration.json in the step "Configure the A1 Policy Management Service" above.
  Different Simulators can use different A1-Interface profiles, for example OSC_2.1.0 and STD_2.0.0 below. Start each simulator instance with the following commands (use separate shells):

  Code Block

  (Each in a new shell) docker run -p 8085:8085 -p 8185:8185 -e A1_VERSION=OSC_2.1.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric1 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8086:8085 -p 8186:8185 -e A1_VERSION=OSC_2.1.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric2 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8087:8085 -p 8187:8185 -e A1_VERSION=STD_2.0.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric3 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8088:8085 -p 8188:8185 -e A1_VERSION=STD_2.0.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric4 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0

  (Note these commands create a deployment scenario aligned towards the sample A1 Policy configuration given above)
  (Note these commands can be run in the background - all in one shell - by using docker run -d -p ..... )
  
  

• For the OSC.2.1.0 simulators create a new A1 Policy Type policy type definition (JSON), and load it into each of the OSC.2.1.0 A1 Simulators instances.
  (Note the format for A1 Policy Type Definitions (JSON) differs for different A1-Interface profiles)
  

  Code Block
  language js title pt1.json collapse true
  { "name": "pt1", "description": "pt1 policy type", "policy_type_id": 1, "create_schema": { "$schema": "http://json-schema.org/draft-07/schema#", "title": "OSC_Type1_1.0.0", "description": "Type 1 policy type", "type": "object", "properties": { "scope": { "type": "object", "properties": { "ueId": { "type": "string" }, "qosId": { "type": "string" } }, "additionalProperties": false, "required": [ "ueId", "qosId" ] }, "qosObjectives": { "type": "object", "properties": { "priorityLevel": { "type": "number" } }, "additionalProperties": false, "required": [ "priorityLevel" ] } }, "additionalProperties": false, "required": [ "scope", "qosObjectives" ] } }

  
  

  • Insert the example policy type into the started OSC_2.1.0 A1 Simulator instances by running these curl commands (in this example to ric1 exposed to port 8085 and ric2 exposed to port 8086):

    Code Block
    language bash
    curl -X PUT -v "http://localhost:8085/a1-p/policytypes/1" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @pt1.json curl -X PUT -v "http://localhost:8086/a1-p/policytypes/1" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @pt1.json

    
    

• For the STD_2.0.0 simulators create a new A1 Policy Type policy type definition (JSON), and load it into each of the STD_2.0.0A1 Simulators instances.
(Note the format for A1 Policy Type Definitions (JSON) differs for different A1-Interface profiles)

  Code Block
  language js title std_qos2_0.0.1.json collapse true
  { "policySchema": { "$schema": "http://json-schema.org/draft-07/schema#", "title": "STD_QOS2_0.1.0", "description": "STD QOS2 policy type", "type": "object", "properties": { "scope": { "type": "object", "properties": { "ueId": { "type": "string" }, "qosId": { "type": "string" } }, "additionalProperties": false, "required": [ "ueId", "qosId" ] }, "qosObjectives": { "type": "object", "properties": { "priorityLevel": { "type": "number" } }, "additionalProperties": false, "required": [ "priorityLevel" ] } } }, "statusSchema": { "$schema": "http://json-schema.org/draft-07/schema#", "title": "STD_QOS_0.2.0", "description": "STD QOS policy type status", "type": "object", "properties": { "enforceStatus": { "type": "string" }, "enforceReason": { "type": "string" }, "additionalProperties": false, "required": [ "enforceStatus" ] } } }

  


  • Insert the example policy type into the started STD_2.0.0 A1 Simulator instances by running these curl commands (in this example to ric3 exposed to port 8087 and ric4 exposed to port 8088):

    Code Block
    language bash
    curl -X PUT -v "http://localhost:8087/policytype?id=STD_QOS2_0.1.0" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @std_qos2_0.0.1.json curl -X PUT -v "http://localhost:8088/policytype?id=STD_QOS2_0.1.0" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @std_qos2_0.0.1.json

Run ONAP A1 Policy Management Service Docker Container

• Run A1 Policy Management Service docker container using the command below, after the A1-Controller and simulators have been fully started.
It may be useful to set the logging level to TRACE level, where you can verify the A1-Controller, A1-Simualtors and A1 Policy Management Service is fully up and running.
The configuration file (application_configuration.json described above) must be mounted as a volume into the container, so absolute path and name of the file must be substituted in the following command:

  Code Block
  language bash title Docker: Run the A1 Policy Management Service
  docker run -p 8081:8081 --network=nonrtric-docker-net --name=a1policymanagmentservice --volume **<Absolute path to application_configuration.json created above>**:/opt/app/policy-agent/data/application_configuration.json nexus3.onap.org:10002/onap/ccsdk-oran-a1policymanagementservice:1.5.0

  Note: Version numbers used in this page may not be the most recent ... you should verify the latest version numbers for released pre-built components in the docker image repository (https://nexus3.onap.org)

  Code Block
  language bash title Optional: Enable TRACE level logging in A1 Policy Management Service collapse true
  curl -X POST  http://localhost:8081/actuator/loggers/org.onap.ccsdk.oran.a1policymanagementservice -H "Content-Type:application/json" -d {\"configuredLevel\":\"trace\"}

  


• Once the Policy Management Service is up and running, it establishes connections to all configured near-RT-RICs (ric1, ric2, ric3, ric4) via the A1 Controller.

• If the a1policymanagmentservice container is configured to log at TRACE level, the following logs entries should appear indicating that connection to the configured RICs has been established successfully via A1 Controller.
