  2. O-RAN - oai-cu-cp, oai-cu-up, oai-du and UE

Using helm to install deployment after configurations

cd ~/oai-v210/charts/oai-5g-ran/oai-cu-cp helm install oai-cu-cp .

wait for cu-cp to start

helm install oai-cu-up ../oai-cu-up helm install oai-du ../oai-du helm install oai-nr-ue ../oai-nr-ue

Testing connection

kubectl exec -it <oai-nr-ue-pod-name> -- bash
#ping towards spgwu/upf
ping -I oaitun_ue1 12.1.1.1
#ping towards google dns
ping -I oaitun_ue1 8.8.8.8
