# This YAML file shows how to deploy the CSI snapshotter together
# with the hostpath CSI driver. It depends on the RBAC rules
# from rbac-csi-snapshotter.yaml and rbac-external-provisioner.yaml.
#
# Because external-snapshotter and external-provisioner get
# deployed in the same pod, we have to merge the permissions
# for the provisioner into the service account. This is not
# necessary when deploying separately.
