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:
Create an installation configuration file, the install-config.yaml
file, by running the installation program and answering its prompts.
Inspect and modify parameters in the install-config.yaml
file.
Make a working copy of the install-config.yaml
file.
Run the installation program with a copy of the install-config.yaml
file.
Then, the installation program creates the OpenShift Container Platform cluster.

This installation program is available for Linux and macOS only. |
You reviewed details about the OpenShift Container Platform installation and update processes.
You have a supported combination of versions in the Support Matrix for OpenShift Container Platform on Red Hat Virtualization (RHV).
You read the documentation on selecting a cluster installation method and preparing it for users.
If you use a firewall, you configured it to allow the sites that your cluster requires access to.
In OpenShift Container Platform 4.9, you require access to the internet to install your cluster.
You must have internet access to:
Access OpenShift Cluster Manager to download the installation program and perform subscription management. If the cluster has internet access and you do not disable Telemetry, that service automatically entitles your cluster.
Access Quay.io to obtain the packages that are required to install your cluster.
Obtain the packages that are required to perform cluster updates.
If your cluster cannot have direct internet access, you can pe |
