Google Kubernetes Engine
GKE clusters must use
Ubuntu OS instead of
Container-Optimized OS, in order to satisfy Longhorn
GKE requires user to manually claim himself as cluster admin to enable RBAC. Before installing Longhorn, run the following command:
kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=<email@example.com>
firstname.lastname@example.org is the user's account name in GCE, and it's case sensitive. See this document for more information.
