Build Code

Build A1 Policy Management Service container

  • Download the ccsdk/oran repo, guilin branch: 

    Code Block
    languagebash
    $ 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:  

  • Copy the file oran/a1-policy-management/config/application_configuration.json  to the current directory and update it with the configuration below.

  • The controller hostname and port values come from and must match those defined in in the sdnc/oam repo oam/installation/src/main/yaml/docker-compose.yml (see the step "Build A1 Controller" further below). The port for http is 8181.

  • Any defined ric host names (in the name and baseUrl for each ric) must match the given docker container names in Near-RT RIC A1 simulator startup described further down - port is always the simulator's internal port 8085 for http or 8185 for https (see the step "Build A1 Controller" further below).

}

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.

Code Block
languagebash
themeMidnight
$ 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 Adapter-enabled SDNC Controller, you need to build the ccsdk & sdnc repo's.

The A1 Policy 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.

ProjectRepoGerrit LinkCommandNote
CCSDKccsdk/parentgit clone "https://gerrit.onap.org/r/ccsdk/parent" -b guilinmvn clean install -Dmaven.test.skip=trueIf the parent artefacts are not release released you need to build this repo in order to build other ccsdk repo's repos (Including ccsdk/oran/a1-adapter)

Make sure you refer the right docker image version in the pom file.(eg: you may need to update ccsdk.docker.version for onap/ccsdk-ansible-server-image from 1.0-STAGING-latest to 1.0-SNAPSHOT-latest)

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 image images in the local docker registry.

Code Block
languagebash
themeMidnight
$ docker images | grep onap
onap/sdnc-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 dependency dependencies but not all are important for A1 policy testing. To bring up the sdnc container for A1 Policy Management testing you can do below change to a number of the not needed services can be removed from the docker compose file.

Edit the docker compose file, oam/installation/src/main/yaml/docker-compose.yaml and keep only sdnc, maria db and ansible images. Rest The rest of the images are not necessary for A1 Policy testing. However if you want to change the DG and run your own DG, you may need to keep the Directed Graph image.

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

  • Start docker containers for each ric defined in oran/a1-policy-management/config/application_configuration.jsonin previous steps 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
    languagebash
    $ 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
    languagebash
    titlept1.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
    languagebash
    $ 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
    The configuration, application_configuration.json, of the controller and rics must be mounted as a volume to the container.

    Code Block
    languagebash
    $ 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
    languagebash
    $ 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 DEBUG trace level, the following logs entries should appear to log to show indicating that connection to the configured RICs has been established successfully via A1 Controller.

...

Code Block
languagebash
$ 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
2020-11-23 16:00:27.495 DEBUG 1 --- [or-http-epoll-6] o.o.c.o.a.clients.A1ClientFactory        : Established protocol version:SDNC_OSC_OSC_V1 for Near-RT RIC: ric2

A1 Policy Management Service Swagger API

For troubleshooting/verification purposes you can view/access the policy-agent swagger API from url: http://localhost:8081/swagger-ui.html

Run OSC Non-RT RIC Control Panel Docker Container

Run docker container using this command: 

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

Open NONRTRIC / A1 Policy Control Panel UI

Dashboard The Control Panel UI can be accessed by pointing the web-browser to this URL: 

http://localhost:8080/

Thee policy type loaded in the simulator should be visible in the table. Instances of the policy type can now be created, updated and deleted.
