`Terminated` state results in unhealthy ingesters

mkieweg opened this issue · comments

commented

Describe the bug
When shutting down ingesters they get into Terminated state. This state is considered unexpected by memberlist resulting in the heartbeat to fail and the instance to be tainted as unhealthy. This requires manual intervention and thus effectively breaks autoscaling.

To Reproduce
Steps to reproduce the behavior:

  1. Start Cortex v1.15.3 using Helm chart v2.1.0
  2. Use HPA to scale down Cortex ingesters

Expected behavior
Ingesters should scale down and remove themselves from the ring without errors

Environment:

  • Infrastructure: EKS
  • Deployment tool: Helm chart v2.1.0
