[tempo-distributed] Container is missing readiness or liveness probe #2966

@alita1991

Description

@alita1991

The Tempo service is currently lacking proper probes, leading to potential issues with monitoring, health checks, and graceful handling of service disruptions. Probes play a critical role in ensuring the stability and reliability of services within our Kubernetes cluster.

This issue was discovered while scanning the helm chart via kube-score:
https://github.com/zegl/kube-score/blob/master/README_PROBES.md

The components with missing readiness probes are:

  • apps/v1/StatefulSet tempo-memcached
  • apps/v1/Deployment tempo-query-frontend
  • apps/v1/Deployment tempo-compactor

The components with missing liveness probes are:

  • apps/v1/StatefulSet tempo-ingester
  • apps/v1/Deployment tempo-distributor
  • apps/v1/Deployment tempo-querier

Is there any reason for not having probes for the given components? If not, what would be the recommendation?
