OpenShift Container Platform requirements

If we are installing a WebSphere Liberty operator on an Red Hat® OpenShit cluster, the environment must meet Red Hat OpenShift Container Platform (OCP) cluster requirements.

OCP requirements

WebSphere Liberty operator requires an
OCP version 4.19,
OCP version 4.18,
OCP version 4.17,
OCP version 4.16,
OCP version 4.15, or
OCP version 4.14 cluster on Linux x86_64 (amd64), Linux on Power (ppc64le), or Linux on IBM Z (s390x) platform, with cluster-admin permissions. To manage OCP projects with OCP CLI (oc) commands, the installation also requires the
OCP CLI.

By default, certificates are generated using the OpenShift certificate manager. To use the manageTLS capability and use a different certificate manager (such as cert-manager) to generate and manage the certificates, we must install it.
