  # instanceID is a label selector to limit the controller's watch to a specific instance. It
  # contains an arbitrary value that is carried forward into its pod labels, under the key
  # workflows.argoproj.io/controller-instanceid, for the purposes of workflow segregation. This
  # enables a controller to only receive workflow and pod events that it is interested about,
  # in order to support multiple controllers in a single cluster, and ultimately allows the
  # controller itself to be bundled as part of a higher level application. If omitted, the
  # controller watches workflows and pods that *are not* labeled with an instance id.
  instanceID: my-ci-controller

  # Parallelism limits the max total parallel workflows that can execute at the same time
