Although the purpose of the Radio Edge Cloud is to run the RAN Intelligent Controller (RIC), the Akraino Release 1 predates the RIC release 1. The manual installation procedure described below does not result in the installation of the RIC. In the REC Continuous Deployment system, as of the Akraino Release 1 timeframe, a Jenkins job deploys a "Release Zero" snapshot of the RIC and runs a small set of tests. These steps may be manually executed and this procedure is descripted in the last section of this WIKI document. Fully automated installation of the RIC as part of the REC will not be complete until sometime after Akraino Release 1. If you are interested in actually interfacing a REC appliance with eNodeB/gNode B and radio infrastructure you should really join the Radio Edge Cloud Project Meetings on a weekly basis and let the REC team know of your interest. We will be happy to coordinate with you and welcome any testing that you can do. |

RIC R0 Installation onto REC
REC Release R1 includes the ability to run the R0 version of the RIC.
This R0 is limited functionality of the RIC plaform, but demonstrates the basic RIC platform components of appmgr, rtmgmr, redis, e2term, etmgr.
Additionally it is possible to load robot test suites to verify functionality, but not all test cases will work in this version of RIC.
As more functionality becomes available, more test cases will work and more tests will be added.
Onboarding RIC R0 is a manual step at present, in future it will be included in the REC build process.
RIC R0 includes scripts to bring up the RIC onto a generic kubernetes platform.
To bring it up on the REC, follow the steps below.
step 1:
Login to the controller 1 as cloudadmin and clone the scripts used to bring up the RIC on a REC cluster.
git clone https://gerrit.akraino.org/r/rec.git
step 2:
Copy the scripts to your home directory
cp rec/workflows/ric_automation.sh rec/workflows/robot.sh rec/workflows/nanobot.sh ./
Step 3:
Run the ric_automation.sh script.
bash ric_automation.sh
Once the script completes, verify the output below indicating successful deployment of the RIC helm charts.
+ helm install localric/ric --namespace ricplatform --name ric-full --set appmgr.appmgr.service.appmgr.extport=30099 --set e2mgr.e2mgr.service.http.extport=30199

Step 4:
Verify the RIC pods are all coming up and running.
[cloudadmin@controller-1 ~]$ kubectl get pods -n ricplatform
NAME READY STATUS RESTARTS AGE
ric-full-appmgr-74b4f68459-rhwf6 1/1 Running 0 2m5s
ric-full-dbaas-877f5788d-rpg87 1/1 Running 0 2m5s
ric-full-e2mgr-f6956b9f8-kxc6q 1/1 Running 0 2m5s
ric-full-e2term-f6556544c-pzxgv 1/1 Running 0 2m5s
ric-full-rtmgr-95f7cb5cc-bfhdx 1/1 Running 0 2m5s
[cloudadmin@controller-1 ~]$
It may take a little time so repeat the command at some intervals.
If they do not come up as Running, you should use standard kubernetes command such as kubectl describe, kubectl logs to troubleshoot and resolve the issue.
Step5:
Now that you have running RIC R0, on the REC, you can install robot test scripts to do more verification of the RIC components. These at present only provide limited testing but more tests will be added later as more functionality is developed in later RIC releases.
