Code change:
Is this a BUG REPORT or FEATURE REQUEST?: /kind bug What happened: When kube-apiserver's livenessProbe suggests that pod is unhealthy, kubelet tries to kill its container with 30 seconds grace period. The container is killed ungracefully with SIGKILL when grace period passes. This happens each time. What you expected to happen: I expected that SIGTERM will be passed to kube-apiserver which will try to gracefully stop before 30 seconds pass (at least in some cases). How to reproduce it (as minimally and precisely as possible): Inject kube-apiserver failure (e.g. ) Watch kubelet logs for container's death You will see that container is killed after 30 seconds each time Anything else we need to know?: I believe the problem is that in kube-apiserver.manifest uses '/bin/sh -c CMD' as a PID1 process which doesn't pass SIGTERM signals to child process. See Environment: Kubernetes version (use ): v1.7.11
/sig node
Looks like without the pipe command will have to be removed which will make the logs hard to track. There is indeed some which makes kube-apiserver run in background and trapping SIGTERM then send a SIGTERM to apiserver's PID.
I think this is the case for all our components, not just kube-apiserver. - FYI
How about using 'exec'-based solution suggested here: In our case it means prepending 'exec': I did changed this in my cluster and the process seems to meet requirements: fd/1 and fd/2 are redirected to /var/log/kube- container is killed instantaneously If everyone is fine with such a solution, I can prepare PR adding 'exec ' in front of all kubernetes/cluster/saltbase/salt/kube-apiserver/*.manifest using '/bin/sh -c CMD' pattern.
Not sure if understand what you mean. Before there was no logs, so /bin/sh -c wasn't needed. -based solution seems to have all required properties. What is your concern about using it?
Umm. just ignore my previous comment. I just tried prepending and it works fine for me.
