Also, you can run the Docker sample, [Example Image with a WebLogic Server Domain](https://github.com/oracle/docker-images/tree/master/OracleWebLogic/samples/12213-domain-home-in-image), manually with the generated `domain.properties` to create a domain home image. **Note**: Oracle recommends keeping the domain home image private in the local repository.
 * Create a Kubernetes domain YAML file, `domain.yaml`, in the directory that is created above. This YAML file can be used to create the Kubernetes resource using the `kubectl create -f` or `kubectl apply -f` command.
