These instructions apply to upgrading operators within the 3.x release family as additional versions are released.
To upgrade the Kubernetes operator, use the helm upgrade command. Make sure that the weblogic-kubernetes-operator repository on your local machine is at the operator release to which you are upgrading. When upgrading the operator, the helm upgrade command requires that you supply a new Helm chart and image. For example:
$ helm upgrade \
--reuse-values \
--set image=oracle/weblogic-kubernetes-operator:3.1.1 \
--namespace weblogic-operator-namespace \
--wait \
weblogic-kubernetes-operator \
kubernetes/charts/weblogic-operator
