See 3. Share the /dockerdata-nfs Folder between Kubernetes Nodes for instruction on how to set this up.


Configuring SDN-C ONAP


Clone OOM project only on Kuberentes Master Node

Note
titleHelm support

OOM deployment is now being done using helm.

It is highly recommended to stop here and continue from this page. Deploying SDN-C using helm chart


As ubuntu user, clone the oom repository.
