Issues with /tmp/loki/ Directory on Startup for ingester, index-gateway, and compactor in Loki v3.4.2 deployed with loki-operator

Hi all,

I am encountering an issue where I get the error mkdir /tmp/loki/ on startup for the ingester, index-gateway, and compactor components when installing Loki v3.4.2 with the Lokistack CRD and Loki Operator v0.8.0.

This issue has been mentioned in a couple of existing GitHub issues:

  • #12797
  • #11631
    However, these issues have been closed without a resolution.

One of the issues suggests patching the StatefulSets with an initContainer to add the missing permissions. This approach works, but only if I also update the lokistack CR to use spec.managementState: Unmanaged. However, I feel like this defeats the purpose of using the operator in the first place.

I’ve looked into the Loki Helm chart, and I see that each component supports specifying initContainers. Unfortunately, this isn’t the case for the Lokistack CRD.

Has anyone found a fix for this issue that doesn’t involve patching and setting managementState to Unmanaged?

Also, is the Loki Operator actively maintained? I see new commits, but I’m wondering if there are any ongoing updates to address issues like this.

Thanks in advance for any insights!
