All objects with graceful deletion allow multiple DELETE calls in the pending state. Namespace is the one outlier, and the error here predates graceful deletion and finalizers. We should make this behavior consistent with other calls and merely indicate success and return the state of the object, the same as if there were pending metadata finalizers. Clients that previously checked for a conflict error during delete to know that the server is already deleting will now no longer receive an error (as if the object were rapidly deleted). There is a small chance that some clients have error checking for this state, but a much larger chance that clients that want to trigger a delete of the namespace do not handle this error case. Discovered in an e2e test that used the framework namespace and triggered deletion of that ns itself, and then the AfterEach step in e2e failed because the namespace was already pending deletion. |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts. It provides 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 your company 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.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd 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.
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.
