 * Create a directory for the generated properties and Kubernetes YAML files for this domain if it does not already exist.  The pathname is `/path/to/weblogic-operator-output-directory/weblogic-domains/<domainUID>`. Note that the script fails if the directory is not empty when the `create-domain.sh` script is executed.
 * Create a proerties file, `domain.properties`, in the directory that is created above. This properties file will be used to create a sample WebLogic Server domain.
-* Build Docker image based on Docker sample [Example Image with a WebLogic Server Domain](https://github.com/oracle/docker-images/tree/master/OracleWebLogic/samples/12213-domain-home-in-image). It will create a sample WebLogic Server domain into the Docker image. You can also 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 domain home image. Note: Oracle recommend 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.
 
 As a convenience, using the `-e` option, the script can optionally create the domain object, which in turn results in the creation of the corresponding WebLogic Server pods and services as well.
