Alternatively create Persistent Volume domain - setup Weblogic Kubernetes ( k8s) Operator in GCP -

 HOWTO

• Domain types https://oracle.github.io/weblogic-kubernetes-operator/samples/domains/
• Domain on Persistent Volume https://oracle.github.io/weblogic-kubernetes-operator/samples/domains/domain-home-on-pv/
• Credentials https://oracle.github.io/weblogic-kubernetes-operator/samples/credentials/
• Storage https://oracle.github.io/weblogic-kubernetes-operator/samples/storage/

This is alternative to Model in image which is preffered solution

See https://danielveselka.blogspot.com/2023/12/setup-weblogic-kubernetes-k8s-operator_14.html

Domain on PV 

• Set the domain resource domain.spec.domainHomeSourceType attribute to PersistentVolume.
• Supply a WebLogic installation in an image and supply a WebLogic configuration as a domain home in a persistent volume.
• Optionally supply the domain resource domain.spec.configuration.initialDomainOnPV section to provide information for the Operator to create the initial domain home.
• Supply WebLogic applications in the persistent volume.
• Update the WebLogic configuration using WLST, or the WebLogic Server Administration Console.
• Optionally use configuration overrides supplied in a Kubernetes ConfigMap. Use this only if WLST, or the WebLogic Server Administration Console does not fit your deployment strategy.
