Automatic merge from submit-queue (batch tested with PRs 60457, 60331, 54970, 58731, 60562). 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>. tests: e2e: empty msg from channel other than stdout should be non-fatal Currently, if the exec websocket encounters a message that is not in the stdout stream, it immediately fails. However it also currently requests the stderr steam in the query params. There doesn't seem to be any guarantee that we don't get an empty message on the stderr stream. Requesting the stderr stream in the query is desirable if, for some reason, something in the container fails and writes to stderr. However, we do not need fail the test if we get an empty message on another stream. If the message is not empty, then that _does_ indicate and error and we should fail. This is the situation we are currently observing with docker 1.13 in the origin CI https://github.com/openshift/origin/issues/18726 @derekwaynecarr @smarterclayton @gabemontero @liggitt @deads2k /sig node |

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.
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.
