CSI configuration

An overview of the HPE SimpliVity CSI driver is available in the section HPE SimpliVity Container Storage Interface (CSI) driver for vSphere.

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-svt-sc'
csi_datastore_name	The datastore name to be created, if it does not already exist	For example, 'gmcg-gke-csi1'
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-svt-sc'
      csi_datastore_name: 'gmcg-gke-csi1'
      csi_datastore_size: '20'
