Charmed Loki Coordinator
loki-coordinator-k8s is a workloadless charm that coordinates the operations of loki-worker charms and routes traffic to them.
It is an essential part of COS HA.
This Charmed Operator handles deployment, scaling, configuration, and Day 2 operations specific to Loki.
This operator drives the Loki worker applications, and it can be composed with other operators to deliver a complex application or service.
Loki-coordinator’s primary task is to ensure that a cluster of Loki worker nodes is consistent (i.e. all required roles are assigned to a certain number of units). Its secondary function is to provide a unified configuration point for the whole cluster. Finally, it deploys and operates nginx to route traffic to the related workers.
This charm on its own does not deploy or operate Loki; the loki bundle deploys a loki-coordinator instance and a loki-worker instance and integrates them. Only then, you will have a functional Loki deployment.
This charm is:
- part of the COS HA bundle
- intended to be used together with
alertmanager-k8s
