The local-path-provisioner module: FAQ

How to configure Prometheus to use local storage for storing data?

Deploy CR LocalPathProvisioner:

apiVersion: deckhouse.io/v1alpha1
kind: LocalPathProvisioner
metadata:
  name: localpath-system
spec:
  nodeGroups:
  - system
  path: "/opt/local-path-provisioner"

spec.nodeGroups must match node group where prometheus pods run.
spec.path - node data path.

Add to the Deckhouse configuration (configMap d8-system/deckhouse):

prometheus: |
  longtermStorageClass: localpath-system
  storageClass: localpath-system

Wait for the restart of Prometheus Pods.
