11.5. Installing a cluster on RHV with customizations

警告

Due to a known issue with installing OpenShift Container Platform versions 4.4 and 4.5 on Red Hat Virtualization (RHV) 4.4.1, you must customize install-config.yaml as described in OpenShift IPI installation on RHV-4.x failed with "Error: timeout while waiting for state to become 'up' (last state: 'down', timeout: 10m0s)". This defect is fixed in RHV 4.4.2.

警告

Installing OpenShift Container Platform version 4.6 on Red Hat Virtualization (RHV) requires RHV version 4.4. If you are running an earlier version of OpenShift Container Platform on RHV 4.3, do not update it to OpenShift Container Platform version 4.6. Red Hat has not tested running OpenShift Container Platform version 4.6 on RHV version 4.3 and does not support this combination. For more information, see OpenShift Container Platform 4.x Tested Integrations (for x86_x64).

You can customize and install an OpenShift Container Platform cluster on Red Hat Virtualization (RHV), similar to the one shown in the following diagram.

The installation program uses installer-provisioned infrastructure to automate creating and deploying the cluster.

To install a customized cluster, you prepare the environment and perform the following steps:

  1. Create an installation configuration file, the install-config.yaml file, by running the installation program and answering its prompts.
  2. Inspect and modify parameters in the install-config.yaml file.
  3. Make a working copy of the install-config.yaml file.
  4. Run the installation program with a copy of the install-config.yaml file.

Then, the installation program creates the OpenShift Container Platform cluster.

For an alternative to installing a customized cluster, see Installing a default cluster.

注記

This installation program is available for Linux and macOS only.
