Discussion:
What happened: liveness/readiness probe fails while pod is terminated. Also it happened only once during the pod termination. The issue started happening after upgrading version to v1.7 from v1.6.X How to reproduce it (as minimally and precisely as possible): execute to delete pod, so status of the nginx-podA1 is changed to , right after that it seems Liveness and Readiness Probe is executed and failed, but only once. Nginx reverse proxy is running in the pod. so I just use method for liveness and readiness Here is my Deployment config. Here is Events log by Environment: Kubernetes version: 1.7.2

PING
Since the upgrade to 1.7, it seems our deployment rollouts have a higher failure rate. Occasionally, the pod would come up, but no readiness probe ever gets started. It stays in that state, blocking the entire deployment. I usually have to delete the pod so it is rescheduled, and a new readiness probe is fired to check. I wonder if these are related issues here.

/reopen /remove-lifecycle rotten We see this consistently with all pods who define a liveness or readiness probe. Whenever we roll out a new deployment, the pods who are terminated will emit a failed liveness/readiness probe AFTER they have been terminated.

We have considered adding a hook that just sleeps for 2-3 seconds, but it seems like a band-aid solution to something that should not happen in the first place. Is this an impossible-to-solve race condition between kubernetes moving parts?

Do you still experience this? This happens to us running kubernetes 1.11.4.
On k8s 1.12.7 and this is happening to me as well.
Server Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.6", GitCommit:"", GitTreeState:"clean", BuildDate:"2018-07-26T10:04:08Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"} still happen. I think just add a phase "Terminateing" in pod, when an pod is in Terminateing just stop check.
I think it still happening in 1.13, why this issue was closed? Logs, !

still experience this on kubernetes 1.12.4. delete event and probe failed event so it seems that after the pod is deleted, the probe keeps running.I am wondering if the probe is started before the pod deletion.

Any progress on this issue? It seems like some kind bug.

16.9 here. Same issue.

I am also facing this issue. We have pods which have a lot of cleanup to do during shutdown, it can take up to 5 mins to terminate gracefully. During this time the livelinessProbe is detecting failure and restarting the pod. not really what we want. I am unable to prevent the service that handles the liveliness check from stopping while the cleanup is happening. It would be better if the pod was immediately removed from the service and the probes stopped while the shutdown is performed. Basically this ends up that k8s never actually is able to terminate the pod.
I will take that point and propose a shutdown probe to API sig.

Same here at 1.18.8

Should I consider a cherry-pick for 1.20 and 1.19? (maybe 1.18 too?)
we're running 1.16 and being hit by this continuously when some of our elixir apps shutdown so cherry-picking it in 1.18 would at least put it closer in our update path :angel:
