# This YAML file shows how to deploy the snapshot controller
# The snapshot controller implements the control loop for CSI snapshot functionality.
# It should be installed as part of the base Kubernetes distribution in an appropriate
# namespace for components implementing base system functionality. For installing with
# Vanilla Kubernetes, kube-system makes sense for the namespace.

# The snapshot controller won't be marked as ready if the v1 CRDs are unavailable.
# The flag --retry-crd-interval-max is used to determine how long the controller
# will wait for the CRDs to become available before exiting. The default is 30 seconds
# so minReadySeconds should be set slightly higher than the flag value.
