Installing the WebLogic Server Kubernetes Operator

We depend on the WebLogic Server Kubernetes Operator to create and manage WebLogic domains. For detailed installation information, see Install the Operator.

In this example, we provide the steps to install the operator 4.0.1 release.

Installing the WebLogic Server Kubernetes Operator

Create a namespace in which to run the operator.

kubectl create namespace weblogic-operator1

Create a service account.

kubectl create serviceaccount -n weblogic-operator1 sample-weblogic-operator-sa

Add the operator chart repository to Helm.

helm repo add weblogic-operator https://oracle.github.io/weblogic-kubernetes-operator/charts

Install the operator with the operator chart with version 4.0.1.

helm install weblogic-operator/weblogic-operator \
  --version 4.0.1 \
  --name weblogic-operator \
  --namespace weblogic-operator1 \
  --set serviceAccount=sample-weblogic-operator-sa \
  --wait

Verification

Wait until the operator pod is running and ready.

kubectl -n weblogic-operator1 get pod

output

NAME                                READY   STATUS    RESTARTS   AGE
weblogic-operator-fcfff877c-c4972   1/1     Running   0          30h

Wait until the domain CRD is registered successfully.

kubectl get crd domains.weblogic.oracle

output

NAME                      CREATED AT
domains.weblogic.oracle   2019-05-28T07:17:26Z

Now the WebLogic Server Kubernetes Operator is running and it's monitoring all namespaces created with the label weblogic weblogic-operator=enabled. The operator will be responsible for creating, running, and managing any WebLogic domains deployed to namespaces with such labels.
