Installing a cluster on OpenStack in a disconnected environment

In {product-title} {product-version}, you can install a cluster on {rh-openstack-first} in a restricted network by creating an internal mirror of the installation release content.

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 verified that {product-title} {product-version} is compatible with your {rh-openstack} version by using the Supported platforms for OpenShift clusters section. You can also compare platform support across different versions by viewing the {product-title} on {rh-openstack} support matrix.

• You created a registry on your mirror host 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 understand performance and scalability practices for cluster scaling, control plane sizing, and etcd. For more information, see Recommended practices for scaling the cluster.

• You have the metadata service enabled in {rh-openstack}.

Next steps

• Customize your cluster.

• If the mirror registry that you used to install your cluster has a trusted CA, add it to the cluster by configuring additional trust stores.

• If necessary, you can opt out of remote health reporting.

• If necessary, see Registering your disconnected cluster

• Configure image streams for the Cluster Samples Operator and the must-gather tool.

• Learn how to use Operator Lifecycle Manager in disconnected environments.

• If you did not configure {rh-openstack} to accept application traffic over floating IP addresses, configure {rh-openstack} access with floating IP addresses.
