Loki 2.6.1 not starting (failed to create memberlist)

[flouis1]

Trying to run Loki through the current version of Helm deployment. Startup of the loki pod is failing with the error message:

log

msg=“module failed” module=memberlist-kv error=“invalid service state: Stopping, expected: Running”

Same issue seen here

Here I assume that your current namespace is jfrog-plg
if not

kc config set-context --current --namespace=jfrog-plg

Pull config

hl get values loki  -o yaml > values.loki.yaml

Fix by adding those line to value.yml

loki:
[...]
  config:
    memberlist:
      bind_addr:
        - ${MY_POD_IP}

  ingester:
    extraArgs:
    - -config.expand-env=true
    extraEnv:
      - name: MY_POD_IP
        valueFrom:
          fieldRef:
            fieldPath: status.podIP

Update install

hl upgrade --install "loki" grafana/loki-stack -f values.loki.yaml

For loki 2.9.6, under singleBinary node, the settings (structuredConfig under loki and extraArgs and extraEnv under singleBinary) worked for me.

  loki:

      runAsGroup: null
