Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Prevent webhooks from affecting admission requests for WebhookConfiguration objects **What this PR does / why we need it**: As it stands now webhooks can be added to the system which make it impossible for a user to remove that webhook, or two webhooks could be registered which make it impossible to remove each other. The first commit of this will add a test to make sure webhook deletion is never blocked by a webhook. This test will fail until the second commit is added which will prevent webhooks from affecting admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects in the admissionregistration.k8s.io group - [x] Test that webhook deletion is never blocked by a webhook ([test fails before second commit](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/59840/pull-kubernetes-e2e-gce/23731/)) - [x] Prevent webhooks from being called on admission requests for [Validating|Mutating]WebhookConfiguration objects - [x] Document this new behavior maybe in another PR **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Part of fixing #59124 (Verifies that it can remove the broken webhook.) **Release note**: ```release-note ValidatingWebhooks and MutatingWebhooks will not be called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects in the admissionregistration.k8s.io group ```
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
For the full story, head over to the developer's documentation.
