# This YAML file contains all API objects that are necessary to run external
# CSI provisioner.
#
# In production, this needs to be in separate files, e.g. service account and
# role and role binding needs to be created once, while stateful set may
# require some tuning.
#
# In addition, mock CSI driver is hardcoded as the CSI driver.
