Create a new image with a domain home by running the [create-domain](http://github.com/oracle/weblogic-kubernetes-operator/blob/main/kubernetes/samples/scripts/create-weblogic-domain/domain-home-in-image/create-domain.sh) script.

Create a new image with a domain home, plus create a domain resource that the operator will use to deploy the image, by running the [create-domain](http://github.com/oracle/weblogic-kubernetes-operator/blob/main/kubernetes/samples/scripts/create-weblogic-domain/domain-home-in-image/create-domain.sh) script.
+
+    The script's behavior is controlled by an inputs file plus command-line options. The script downloads the [WebLogic Image Tool](https://oracle.github.io/weblogic-image-tool/) and [WebLogic Deploy Tool](https://oracle.github.io/weblogic-deploy-tooling/) and uses these tools to create a new image with a domain home. The script also creates a domain resource YAML file that references the image, and, if the `-e` option is specified, deploys the domain resource to Kubernetes. For a detailed understanding of the steps that the `create-domain.sh` script performs for you, see the bulleted items under [Use the script to create a domain]({{< relref "/samples/simple/domains/domain-home-in-image/#use-the-script-to-create-a-domain" >}})
