  ## NOTE: 'key' and 'certificate' are expected in PEM format
  ## NOTE: 'name' should line up with a 'secretName' set further up
  ## If it is not set and you're using cert-manager, this is unneeded, as it will create a secret for you with valid certificates
  ## If it is not set and you're NOT using cert-manager either, self-signed certificates will be created valid for 365 days
  ## It is also possible to create and manage the certificates outside of this helm chart
  ## Please see README.md for more information
