12.6.8. Creating the RHCOS image for restricted network installations

Download the Red Hat Enterprise Linux CoreOS (RHCOS) image to install OpenShift Container Platform on a restricted network VMware vSphere environment.


  • Obtain the OpenShift Container Platform installation program. For a restricted network installation, the program is on your mirror registry host.


  1. Log in to the Red Hat Customer Portal’s Product Downloads page.
  2. Under Version, select the most recent release of OpenShift Container Platform 4.5 for RHEL 8.


    The RHCOS images might not change with every release of OpenShift Container Platform. You must download images with the highest version that is less than or equal to the OpenShift Container Platform version that you install. Use the image versions that match your OpenShift Container Platform version if they are available.

  3. Download the Red Hat Enterprise Linux CoreOS (RHCOS) - vSphere image.
  4. Upload the image you downloaded to a location that is accessible from the bastion server.

The image is now available for a restricted installation. Note the image name or location for use in OpenShift Container Platform deployment.
