 * Deploy an operator that manages all WebLogic domains in all namespaces in a Kubernetes cluster, or that only manages domains in a specific subset of the namespaces, or that manages only domains that are located in the same namespace as the operator. At most, a namespace can be managed by one operator.
 * Supply WebLogic domain configuration using:
   * _Model in Image_: Includes [WebLogic Deploy Tooling](https://github.com/oracle/weblogic-deploy-tooling) models and archives in a container image.
+     * **NOTE**: Model in Image without auxiliary images (the WDT model and installation files are included in the same image with the WebLogic Server installation) is deprecated in WebLogic Kubernetes Operator version 4.0.7. Oracle recommends that you use Model in Image _with_ [auxiliary images]({{< relref "/managing-domains/model-in-image/auxiliary-images.md" >}}).
   * _Domain in Image_: Includes a WebLogic domain home in a container image.
      * **NOTE**: The Domain in Image [domain home source type]({{< relref "/managing-domains/choosing-a-model/_index.md" >}}) is deprecated in WebLogic Kubernetes Operator version 4.0. Oracle recommends that you choose either Domain on PV or Model in Image, depending on your needs.
   * _Domain on PV_: Locates WebLogic domain homes in a Kubernetes PersistentVolume (PV). This PV can reside in an NFS file system or other Kubernetes volume types.
