I’m testing a deployment of one OpenShift Nightly 4.7 dev preview.
You can download the dev preview here: https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp-dev-preview/pre-release/
$ wget https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp-dev-preview/pre-release/openshift-client-linux-4.7.0-0.nightly-2020-10-27-051128.tar.gz
$ wget https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp-dev-preview/pre-release/openshift-install-linux-4.7.0-0.nightly-2020-10-27-051128.tar.gz
After having started the “Installer Provisioned Infrastructure (IPI)” deployment, we can check the RHCOS version used with OCP 4.7 here in the temporary bootstrap node:
