Prometheus Config

This image provides Prometheus configuration via Rancher Metadata. The provided Rancher Metadata is written to /etc/prom-conf/prometheus.yml of the container and can be used by a Prometheus Container via volumes_from.

Configuration allows to specify:

• prometheus config file content servers via metadata/prometheus/config See example configuration below.
