Overview of advanced installation topics

The GKE on-prem documentation provides an initial installation journey that makes several choices to keep the experience easy and straightforward. When you complete the initial installation journey, you have an admin cluster and a small user cluster.

This section of the documentation has a collection of advanced topics related to setting up your vSphere environment and installing GKE on-prem.

For example, in the initial installation journey, you create a user cluster that has three nodes. Given that the cluster has only three nodes, the documentation can list simple CPU, RAM, and storage requirements for your vSphere environment. Going forward, you might want to create a user cluster that has more than three nodes. In that case, you should read CPU, RAM, and storage requirements, which gives detailed instructions on how to calculate your resource requirements depending on your cluster size and the types of workloads you intend to run.

The initial installation journey used the F5 BIG-IP load balancer along with integrated load balancing mode. For an overview of load balancing modes and instructions on how to manually configure some alternatives to F5 BIG-IP, see Setting up your load balancer.

For information on how to use OpenID Connect for authenticating clients of your user clusters, see Authenticating with OIDC.

The following topics give detailed instructions for installing GKE on-prem. In particular, these topics show how to configure GKE on-prem to work with a private Docker registry, which you might want as an alternative to using Container Registry.
