Description

The ruler jsonnet supports setting local storage mode, but requires the user to do the rest of the plumbing to make this work, i.e. making the file available on every pod.

To make the ruler trivial to deploy using jsonnet for a newcomer, the local mode should (either by default, or as an option) also deploy a ConfigMap so that the contents of the rules file can be changed from the jsonnet.

Contributor guide

Research direction
Examine the existing ruler jsonnet template and the local storage configuration. Identify where the rules file path is defined and how a ConfigMap can be created and mounted to replace the direct file reference.
