          # following annotations:
          #
          # * `prometheus.io/scrape`: Only scrape pods that have a value of `true`
          # * `prometheus.io/path`: If the metrics path is not `/metrics` override this.
          # * `prometheus.io/port`: Scrape the pod on the indicated port instead of the
          # pod's declared ports (default is a port-free target if none are declared).
