This repository defines the OpenShift node image. This is the rhel-coreos or
stream-coreos image in the OpenShift release payload.
The extensions image (i.e. rhel-coreos-extensions) is also defined here, in
the extensions directory.
Note
Historically, this repo also contained the manifests for RHEL CoreOS (RHCOS)
and CentOS Stream CoreOS (SCOS). These manifests now live in a separate
repo. That repo produces a
base image containing only RHEL/CentOS Stream content. This repo builds
FROM that base image and adds OpenShift components (kubelet, oc,
cri-o, etc.).
