Bug Report

Hi thanks for elastic stack! However, Fleet server does not have a liveness probe, thus it cannot be auto-restarted even if it fails.

What did you do? Use ECK to deploy a fleet server

What did you expect to see? have liveness probe

What did you see instead? Under which circumstances? not have

Environment k8s

• ECK version: latest

• Kubernetes information:

  insert any information about your Kubernetes environment that could help us:

  • On premise ? yes
  • Cloud: GKE / EKS / AKS ?
  • Kubernetes distribution: Openshift / Rancher / PKS ?

  for each of them please give us the version you are using

  $ kubectl version

• Resource definition:

  if relevant insert the resource definition

• Logs:

  insert operator logs or any relevant message to the issue here

I think Fleet server usually terminates on failure and auto-restarts therefore. What kind of liveness probe did you have in mind?

Hi thanks for the reply. I do see sometimes it stucks, i.e. my java spring program runs normally, the elasticsearch runs normally, but fleet stops doing anything and thus the APM data is not sent into elasticsearch. I hope the probe can avoid this problem.
