Unable to start ruler component

Grafana Loki
1

I’m trying spin up loki with helm chart, where I enabled ruler configuration with this

ruler:
  enabled: true
  storage:
    type: local
    local:
      directory: /rules
  rule_path: /tmp/scratch
  alertmanager_url: http://alertmanager:9093
  ring:
    kvstore:
      store: inmemory
  enable_api: true

However, when I start the loki via helm, the initial logs states this.

level=info ts=2021-07-23T13:07:34.860485766Z caller=main.go:130 msg="Starting Loki" version="(version=2.2.1, branch=HEAD, revision=babea82ef)"

level=info ts=2021-07-23T13:07:34.868057538Z caller=module_service.go:59 msg=initialising module=server

I believe the message RulerStorage is nil. Not starting the ruler. is the reason why ruler component couldn’t start?

Is there any way that I can configure the ruler block and start in values.yaml?
