# This YAML file contains all API objects that are necessary to run external
2+
# CSI snapshotter.
3+
#
4+
# In production, this needs to be in separate files, e.g. service account and
5+
# role and role binding needs to be created once, while stateful set may
6+
# require some tuning.
7+
#
8+
# In addition, hostpath CSI driver is hardcoded as the CSI driver.
