grafana-cloud.yml

# Custom Prometheus rules. Use prometheus/custom-prom.yml which will be appended to
# /etc/prometheus/prometheus.yml inside the prometheus container. It will be appended after
# the last scrape target that the entrypoint script adds.
#
# You could add additonal scrape targets as well as additional global sections such as remote-write.
# This file is called grafana-cloud.yml as adding a remote write to Grafana Cloud is likely a
# common use case. It properly is a Prometheus without Grafana and the ability to add custom
# content to prometheus.yml
