+# This YAML file contains all API objects that are necessary to run external

+#
+# 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, hostpath CSI driver is hardcoded as the CSI driver.
