prometheus-remote-read-updater

This is kubernetes custom controller designed for a very specific use-case. It watches the current replica count of a statefulset in a namespace and updates the remote-read endponts of a prometheus config accordingly. The watched statefulset pods are meant to be prometheus shards and the configmap to be updated is meant to contain a valid prometheus config("prometheus.yml").

Environment variables

The controller requires the following environment variables to be set to work properly

Name	Description
STS_NAME	statefulset to be watched
NAMESPACE	namespace of the statefulset to be watched
CONFIG_TO_UPDATE	configmap containing the prometheus configuration("prometheus.yml")
