This page describes how to get the release A version of NonRTRIC up and running locally with two separate NearRT-RIC simulator docker containers.

All four components of the NonRTRIC repo run inside docker containers and communicate via a docker network. Details of the architecture can be found from Release A page.

Project Requirements

  • Java 11 (make sure that JAVA_HOME environment variable points to correct Java version)
  • Maven 3.6
  • Docker and docker-compose (latest)

Build Code

Download the nonrtric repo: 

     git clone "https://gerrit.o-ran-sc.org/r/nonrtric" -b Amber

Configure policy-agent

To support local test with two separate NearRT-RIC simulator instances the following modifications must be done:  

  • change the 'a1ControllerBaseUrl' in nonrtric/policy-agent/config/application.yaml file of policy-agent to http://a1-controller-container:8181 
    • The above hostname and port values come from and must match those defined in nonrtric/sdnc-a1-controller/oam/installation/src/main/yaml/docker-compose.yml
    • The default URL to be replaced (http://sdnc.onap:8282) is used in Kubernetes-based ONAP deployment
  • The following step is required only if you want to run more than the default ric1 nearRT-RIC simulator instance
    • replace the content of nonrtric/policy-agent/config/application_configuration.yaml with the configuration below
    • any defined ric names must match the given docker container names in nearRT-RIC simulator startup - port is always the simulator's internal 8085

application_configuration.yaml
{
   "config": {
      "//description": "Application configuration",
      "ric": [
         {
            "name": "ric1",
            "baseUrl": "http://ric1:8085/",  
            "managedElementIds": [
               "kista_1",
               "kista_2"
            ]
         },
         {
            "name": "ric2",
            "baseUrl": "http://ric2:8085/",
            "managedElementIds": [
               "kista_3",
               "kista_4"
            ]
         }
      ]
   }
}

Verify dashboard configuration

(warning) Note that nonrtric/dashboard/webapp-backend/src/main/resources/application.properties default property value policycontroller.url.prefix = http://policy-agent-container:8081 assumes that policy agent is started with name policy-agent-container and exposes port 8081 (as is done below)! 

Build the code and create docker images

To build docker images of sdnc-a1-controller, policy-agent, near-rt-ric-simulator and nonrtric-dashboard:

cd nonrtric
mvn clean install -Dmaven.test.skip=true

Run A1 Controller Docker Container

  • A1 Controller must be started first to set up docker network
  • Change directory to: 
    cd nonrtric/sdnc-a1-controller/oam/installation/src/main/yaml
  • Run docker container using the command below  
    docker-compose up a1-controller
    • the container is ready once message "Healthcheck Passed in XX seconds." appears
    • note that certificate-related errors "cp: can't stat '/opt/opendaylight/current/certs/*': No such file or directory" and "Error: File not found in path entered" can be ignored 
  • The Karaf logs of A1 controller can be seen using the following commands: 
    docker exec -it a1-controller-container sh
    cd opt/opendaylight/data/log/
    tail -f karaf.log


Run Near-RT-RIC Simulator Docker Containers

  • Start docker containers for each ric defined in nonrtric/policy-agent/config/application_configuration.yaml  in previous steps using following commands (in this example for ric1 and ric2): 
    docker run -p 8085:8085 --network=nonrtric-docker-net --name=ric1 o-ran-sc/near-rt-ric-simulator:1.0.1-SNAPSHOT
    docker run -p 8086:8085 --network=nonrtric-docker-net --name=ric2 o-ran-sc/near-rt-ric-simulator:1.0.1-SNAPSHOT
  • Change directory to:  
    cd nonrtric/near-rt-ric-simulator/ric-plt/a1
  • Put an example policy_type into all the started near-rt-ric-simulator instances by running these curl commands (in this example to ric1 exposed to port 8085 and ric2 exposed to port 8086):
    curl -X PUT -v "http://localhost:8085/policytypes/STD_QoSNudging_0.2.0" -H "accept: application/json" \
    -H "Content-Type: application/json" --data-binary @policy_type_STD_QoSNudging_0.2.0.json

    curl -X PUT -v "http://localhost:8086/policytypes/STD_QoSNudging_0.2.0" -H "accept: application/json" \
    -H "Content-Type: application/json" --data-binary @policy_type_STD_QoSNudging_0.2.0.json

Run Policy-agent Docker Container

  • Run docker container using this command: 
    docker run -p 8081:8081 --network=nonrtric-docker-net --name=policy-agent-container o-ran-sc/nonrtric-policy-agent:1.0.0-SNAPSHOT

(warning) Note on automatic A1 Client selection

Once policy-agent is up and running, it establishes connections to all configured NearRT-RICs. It has multiple A1 clients to select from and selection is done dynamically based on connectivity. Selection of A1 client is not clearly visible for user, but policy-agent logs can be grepped to see which client was selected.

The two grepping examples below show how either SDNC_OSC A1 client or STD A1 client was selected - these translate into options A and B described on the Testing End to End call in release A page.

SDNC A1 Client
$ docker logs policy-agent | grep "protocol version"
2020-03-30 05:33:21.765 DEBUG 1 --- [or-http-epoll-2] o.o.policyagent.clients.A1ClientFactory  : Recover ric: ric2, protocol version:SDNC_OSC
2020-03-30 05:33:21.784 DEBUG 1 --- [or-http-epoll-1] o.o.policyagent.clients.A1ClientFactory  : Recover ric: ric1, protocol version:SDNC_OSC


STD A1 Client
$ docker logs policy-agent | grep "protocol version"
2020-04-03 12:06:54.548 DEBUG 1 --- [or-http-epoll-1] o.o.policyagent.clients.A1ClientFactory  : Recover ric: ric1, protocol version:STD_V1
2020-04-03 12:06:54.552 DEBUG 1 --- [or-http-epoll-2] o.o.policyagent.clients.A1ClientFactory  : Recover ric: ric2, protocol version:STD_V1

Run Non-RT-RIC Dashboard Docker Container

  • Run docker container using this command: 
    docker run -p 8080:8080 --network=nonrtric-docker-net o-ran-sc/nonrtric-dashboard:1.0.1-SNAPSHOT
