CSI configuration

User cluster storage configuration

Configuration for CSI storage is specified on a cluster-by-cluster basis, in the all.yml configuration file, using fields in the cluster definition structure gke_cluster_config structure. For each user cluster, you can specify a storage class and configure a datastore:

Field	Description	Value
csi_storageclass_name	The name of the storage class to use for the user cluster	For example, 'gmcg-vmware-sc'
csi_datastore_name	The datastore name to be created, if it does not already exist	For example, 'gmcg-gke-vmwarecsi'
csi_datastore_size	The size in gigabytes for the datastore	For example, '20'

An example for CSI configuration in a user cluster is shown below:

gke_cluster_config:
    - name: 'user-cluster-1'
      type: 'user'
      ...
      csi_storageclass_name: 'gmcg-vmware-sc'
      csi_datastore_name: 'gmcg-gke-vmwarecsi'
      csi_datastore_size: '20'
