We can also install the WebSphere Liberty operator on Kubernetes 1.30, 1.29, 1.28, or 1.27 for Linux x86_64, Linux on Power (ppc64le), and Linux on IBM Z (s390x).

We can install WebSphere Liberty operator to watch its own namespace, watch another namespace, or watch all namespaces in the cluster. We can install multiple operators in a single cluster. For issues or limitations that affect installation, see Known operator issues and limitations.

Prepare the environment and then install WebSphere Liberty operator with the Red Hat OpenShift console or CLI, or using kubectl in Kubernetes environments. If the environment is not connected to an outside network, install WebSphere Liberty operator in an air gap environment. After the installation completes, validate the installation.

A cluster administrator prepares the environment and completes the installation.
