Kubernetes Submit Queue 00938eac64 Merge pull request #42741 from kargakis/avoid-ns-skew
Automatic merge from submit-queue (batch tested with PRs 43481, 43419, 42741, 43480)

controller: work around milliseconds skew in AddAfter

AddAfter is not requeueing precisely after the provided time and may
skew for some millieseconds. This is really important because controllers
don't relist often so a missed check because of ms difference is
essentially dropping the key. For example, in [1] the test requeues a
Deployment for a progress check after 10s[2] but the Deployment is synced
9ms earlier ending up in the controller not recognizing the Deployment as
failed thus dropping it from the queue w/o any error. The drop is fixed by
forcing the controller to resync the Deployment but we are going to resync
after the full duration.

@deads2k if you don't like this I am going to handle this on a case by case basis

Kubernetes

Submit Queue Widget GoDoc Widget


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.
