# 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. gcrKeyPath: <path to GCR service account key> sshPrivateKeyPath: <path to SSH private key, used for node access> gkeConnectAgentServiceAccountKeyPath: <path to Connect agent service account key> gkeConnectRegisterServiceAccountKeyPath: <path to Hub registration service account key> cloudOperationsServiceAccountKeyPath: <path to Cloud Operations service account key> --- apiVersion: v1 kind: Namespace metadata: name: cluster-example --- apiVersion: baremetal.cluster.gke.io/v1 kind: Cluster metadata: name: example namespace: cluster-example spec: # Cluster type.
