The script can be run with a --dry-run=server option to allow you to review the changes that would be made to your cluster.\n\nThe YAML template used by the script may also be used to deploy the webhooks and associated objects manually (with appropriate substitutions for the parameters)\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
