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.json 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

{
   "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

 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 -d 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.json  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 once A1 Controller and simulators have been fully started (see note below):: 

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

 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.

$ 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

$ docker logs policy-agent | grep "protocol version"
