1.1. About this release
Red Hat OpenShift Container Platform (RHBA-2020:2409) is now available. This release uses Kubernetes 1.18 with CRI-O runtime. New features, changes, and known issues that pertain to OpenShift Container Platform 4.5 are included in this topic.
Red Hat did not publicly release OpenShift Container Platform 4.5.0 as the GA version and, instead, is releasing OpenShift Container Platform 4.5.1 as the GA version.
OpenShift Container Platform 4.5 clusters are available at https://cloud.redhat.com/openshift. The Red Hat OpenShift Cluster Manager application for OpenShift Container Platform allows you to deploy OpenShift clusters to either on-premise or cloud environments.
OpenShift Container Platform 4.5 is supported on Red Hat Enterprise Linux 7.7 or later, as well as Red Hat Enterprise Linux CoreOS (RHCOS) 4.5.
You must use RHCOS for the control plane, which are also known as master machines, and can use either RHCOS or Red Hat Enterprise Linux 7.7 or later for compute machines, which are also known as worker machines.
Because only Red Hat Enterprise Linux version 7.7 or later is supported for compute machines, you must not upgrade the Red Hat Enterprise Linux compute machines to version 8.
With the release of OpenShift Container Platform 4.5, version 4.2 is now end of life. For more information, see the Red Hat OpenShift Container Platform Life Cycle Policy.
