Managing many clusters

While the scripts all use a default testcluster, they have been developed and tested to manage many clusters from a single management node. Copy the ~/cluster-defaults/clusterctl.yaml file to ~/MYCLUSTER/clusterctl.yaml and edit the copy to describe the properties of the cluster to be created. Use ./create_cluster.sh MYCLUSTER then to create a workload cluster with the name MYCLUSTER. You will find the kubeconfig file in ~/MYCLUSTER/MYCLUSTER.yaml, granting its owner admin access to that cluster. Likewise, delete_cluster.sh and the apply_*.sh scripts take a cluster name as parameter.

This way, dozens of clusters can be controlled from one management server.

You can add credentials from different projects into ~/.config/openstack/clouds.yaml and reference them in the OPENSTACK_CLOUD setting in clusterctl.yaml, this way managing clusters in many different projects and even clouds from one management server.
