# The relabeling allows the actual pod scrape endpoint to be configured via the

# 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).
