Oracle strongly recommends storing the container images that contain a WebLogic domain home as private in the container registry. In addition to any local registry, public container registries include GitHub Container Registry and the Oracle Cloud Infrastructure Registry (OCIR).
The WebLogic domain home that is part of a Domain in Image image contains sensitive information about the domain including keys and credentials that are used to access external resources (for example, the data source password). In addition, the image may be used to create a running server that further exposes the WebLogic domain outside of the Kubernetes cluster.
For information about setting up Kubernetes to access a private registry, see Set up Kubernetes to access domain images.
