This page describes how to get the Guilin release version of NonA1-RT RIC Policy functions up and running locally with two separate Near-RT RIC A1 simulator docker containers providing OSC_2.1.0 version of A1 interface.

All four components of the Nonthese Non-RT RIC function run as docker containers and communicate via a private docker network. Details of the architecture can be found from Guilin Release page.

Build Code

Build A1 Policy Management Service container

• Download the ccsdk/oran repo, guilin branch: 

  Code Block
  language bash
  $ git clone "https://gerrit.onap.org/r/ccsdk/oran" -b guilin

  
  

Configure the A1 Policy Management Service

To support local test with two separate Near-RT RIC simulator instances:  

...

{
  "config": {
    "//description": "Application configuration",
    "controller": [
      {
        "name": "controller1",
        "baseUrl": "http://sdnc_controller_container:8181",
        "userName": "admin",
        "password": "Kp8bJ4SXszM0WXlhak3eHlcse2gAw84vaoGGmJvUy2U"
      }
    ],
    "ric": [
      {
        "name": "ric1",
        "baseUrl": "http://ric1:8085/",
        "controller": "controller",
        "managedElementIds": [
          "kista_1",
          "kista_2"
        ]
      },
      {
        "name": "ric2",
        "baseUrl": "http://ric2:8085/",
        "controller": "controller",
        "managedElementIds": [
          "kista_3",
          "kista_4"
        ]
      }
    ]
  }
}

Build the code and create docker image

To build docker image of the policy management service:

...

If the build is successful an image with following name and tag shall be built, use the command 'docker images' to view the newly built the image in the local docker registry.

$ docker images
onap/ccsdk-oran-a1policymanagementservice 1.0.23-SNAPSHOT

Build A1 Adapter for Controller

Build the code and create docker images

A1 Policy Adapter is a feature developed within CCSDK which is can then be installed in SDNC Karaf Server. To build & run the A1-enabled SDNC Controller, you need to build the ccsdk & sdnc repo's.

The A1 The Controller provides a Northbound Interface for A1 operations to do policy management in , to be used only by the A1 Policy Management Service, allowing it to pass messages over the A1 interface to Near-RealTime RICs in the RAN.

Use the downloaded repo 'ccskccsdk/oran' as in the previous step, "Build A1 Policy Management Service container"

...

After you build the A1 adapter artefacts, down download below CCSDK/SDNC repo's repos and build them in the following order.

If the builds are successful, images with following name and tag shall be exist, use the command 'docker images' to view the newly built the images in the local docker registry.

$ docker images | grep onap
onap/sdnc-image latest
onap/sdnc-ansible-server-image latest
onap/admportal-sdnc-image latest
onap/ccsdk-dgbuilder-image latest
onap/sdnc-ueb-listener-image latest
onap/sdnc-dmaap-listener-image:latest

Run A1-enabled Controller

To view the A1 policy operations, you need to run the SDNC docker image. This image has few other docker image dependencies but not all are important for A1 policy testing. To bring up the sdnc container for A1 Policy Management testing a number of the not needed services can be removed from the docker compose file.

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

• Start docker containers for each ric defined in oran/a1-policy-management/config/application_configuration.json in the step for "Configuration Policy Management Service" (in this example for ric1 and ric2) and providing A1 interface version OSC_2.1.0 with the following commands (use separate shells):

  Code Block
  language bash
  $ 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:1000410002/o-ran-sc/a1-simulator:2.01.0 $ 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:1000410002/o-ran-sc/a1-simulator:2.01.0

  
  

• Create a policy type json to load into the A1 simulators

  Code Block
  language bash title pt1.json
  { "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" ] } }

  
  

• Put the example policy type into the started 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

  
  

Run ONAP A1 Policy Management Service Docker Container

• Run docker container using this command once the A1-enabled Controller and simulators have been fully started and optionally set the logging level to trace (the curl command will not work until the container is fully up and running).
  The configuration, application application_configuration.json,   of the controller and rics must be mounted as a volume to the container.

  Code Block
  language bash
  $ docker run -p 8081:8081 --network=nonrtric-docker-net --name=policy-agent-container --volume <Absolute path to application_configuration.json created above>:/opt/app/policy-agent/data/application_configuration.json onap/ccsdk-oran-a1policymanagementservice:1.0.23-SNAPSHOT

  
  

  Code Block
  language bash
  $ 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 and ric2) via the A1 Controller.

• If the policy-agent-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.

...

$ docker logs policy-management-service | grep "protocol version" 
2020-11-23 16:00:27.484 DEBUG 1 --- [or-http-epoll-5] o.o.c.o.a.clients.A1ClientFactory        : Established protocol version:SDNC_OSC_OSC_V1 for Near-RT RIC: ric1

Run OSC Non-RT RIC Control Panel Docker Container

Run docker container using this command: 

$ docker run -p 8080:8080 --network=nonrtric-docker-net nexus3.o-ran-sc.org:1000410002/o-ran-sc/nonrtric-controlpanel:2.01.0
