Automatic merge from submit-queue reset resultRun on pod restart xref https://bugzilla.redhat.com/show_bug.cgi?id=1455056 There is currently an issue where, if the pod is restarted due to liveness probe failures exceeding failureThreshold, the failure count is not reset on the probe worker. When the pod restarts, if the liveness probe fails even once, the pod is restarted again, not honoring failureThreshold on the restart. ```yaml apiVersion: v1 kind: Pod metadata: name: busybox spec: containers: - name: busybox image: busybox command: - sleep - "3600" livenessProbe: httpGet: path: /healthz port: 8080 initialDelaySeconds: 3 timeoutSeconds: 1 periodSeconds: 3 successThreshold: 1 failureThreshold: 5 terminationGracePeriodSeconds: 0 ``` Before this PR: ``` $ kubectl create -f busybox-probe-fail.yaml pod "busybox" created $ kubectl get pod -w NAME READY STATUS RESTARTS AGE busybox 1/1 Running 0 4s busybox 1/1 Running 1 24s busybox 1/1 Running 2 33s busybox 0/1 CrashLoopBackOff 2 39s ``` After this PR: ``` $ kubectl create -f busybox-probe-fail.yaml $ kubectl get pod -w NAME READY STATUS RESTARTS AGE busybox 0/1 ContainerCreating 0 2s busybox 1/1 Running 0 4s busybox 1/1 Running 1 27s busybox 1/1 Running 2 45s ``` ```release-note Fix kubelet reset liveness probe failure count across pod restart boundaries ``` Restarts are now happen at even intervals. @derekwaynecarr |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
If you are less impatient, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
