Im Folgenden finden Sie ein Beispiel für die YAML-Datei, die erstellt wird, wenn Sie den Befehl bmctl create cluster ausführen. Weitere Informationen zu diesem Befehl und wie Sie damit verschiedene Arten von Clusterkonfigurationen erstellen, finden Sie in den folgenden Themen:
- Installationsübersicht: Bereitstellungsmodell auswählen
- Administratorcluster erstellen
- Nutzercluster erstellen
- Hybridcluster erstellen
- Eigenständige Cluster erstellen

# bmctl configuration variables. Because this section is valid YAML but not a valid Kubernetes
# resource, this section can only be included when using bmctl to
# create the initial admin/hybrid cluster. Afterwards, when creating user clusters by directly
# applying the cluster and node pool resources to the existing cluster, you must remove this
# section.

# Cluster type. This can be:
# 1) admin: to create an admin cluster. This can later be used to create user clusters.
# 2) user: to create a user cluster. Requires an existing admin cluster.
# 3) hybrid: to create a hybrid cluster that runs admin cluster components and user workloads.
# 4) standalone: to create a cluster that manages itself, runs user workloads, but does not manage other clusters.
