b. Upgrade an operator release

These instructions apply to upgrading operators within the 3.x release family as additional versions are released.

  1. On the master node, download the new WebLogic Kubernetes Operator source code from the operator github project:

    $ mkdir <workdir>/weblogic-kubernetes-operator-3.X.X
    $ cd <workdir>/weblogic-kubernetes-operator-3.X.X
    $ git clone https://github.com/oracle/weblogic-kubernetes-operator.git --branch v3.X.X 
    

    For example:

    $ mkdir /scratch/OIGK8S/weblogic-kubernetes-operator-3.X.X
    $ cd /scratch/OIGK8S/weblogic-kubernetes-operator-3.X.X
    $ git clone https://github.com/oracle/weblogic-kubernetes-operator.git --branch v3.X.X  
    

    This will create the directory <workdir>/weblogic-kubernetes-operator-3.X.X/weblogic-kubernetes-operator

  2. Run the following helm command to upgrade the operator:

    $ cd <workdir>/weblogic-kubernetes-operator-3.X.X/weblogic-kubernetes-operator
    $ helm upgrade --reuse-values --set image=ghcr.io/oracle/weblogic-kubernetes-operator:3.X.X --namespace <sample-kubernetes-operator-ns> --wait weblogic-kubernetes-operator kubernetes/charts/weblogic-operator
    

    For example:

    $ cd /scratch/OIGK8S/weblogic-kubernetes-operator-3.X.X/weblogic-kubernetes-operator
    $ helm upgrade --reuse-values --set image=ghcr.io/oracle/weblogic-kubernetes-operator:3.X.X --namespace operator --wait weblogic-kubernetes-operator kubernetes/charts/weblogic-operator
    

    The output will look similar to the following:

    Release "weblogic-kubernetes-operator" has been upgraded. Happy Helming!
    NAME: weblogic-kubernetes-operator
    LAST DEPLOYED: Tue Mar 15 09:24:40 2022
    NAMESPACE: operator
    STATUS: deployed
    REVISION: 3
    TEST SUITE: None
    
  3. Verify that the operator’s pod and services are running by executing the following command:

    $ kubectl get all -n <sample-kubernetes-operator-ns>
    

    For example:

    $ kubectl get all -n opns
    

    The output will look similar to the following:
