Installing a cluster on {ibm-power-server-title} in a disconnected environment

In {product-title} {product-version}, you can install a cluster on {ibm-cloud-name} in a restricted network by creating an internal mirror of the installation release content on an existing Virtual Private Cloud (VPC) on {ibm-cloud-name}.

Prerequisites

You reviewed details about the {product-title} installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
You configured an {ibm-cloud-name} account to host the cluster.
You mirrored the images for a disconnected installation to your registry and obtained the imageContentSources data for your version of {product-title}.

Important

Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
You have an existing VPC in {ibm-cloud-name}. When installing a cluster in a restricted network, you cannot use the installer-provisioned VPC. You must use a user-provisioned VPC that satisfies one of the following requirements:
- Contains the mirror registry
- Has firewall rules or a peering connection to access the mirror registry hosted elsewhere
If you use a firewall, you configured it to allow the sites that your cluster requires access to.
You configured the ccoctl utility before you installed the cluster. For more information, see Configuring the Cloud Credential Operator utility.
