Andrew Lytvynov 9269da53f3 spdy: add optional periodic Pings on the connection
When an SPDY connection goes over an intermediate box (proxy or load
balancer, e.g. AWS ELB), it can get interrupted due to idleness (default
in ELB is 60s).  For example, this happens with `kubectl exec` sessions
are left open without any activity for a while.

TCP-level keep-alives are not sufficient for all intermediate boxes,
they may pay attention to application-layer traffic only. SPDY pings
make the connection appear active, letting it survive a period of
idleness.

Note: this commit adds support for pings in
`k8s.io/apimachinery/pkg/util/httpstream/spdy`, but doesn't enable it
anywhere in the calling code. There is no behavior change for existing
callers.

Kubernetes

GoDoc Widget CII Best Practices


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 use Kubernetes code as a library in other applications, see the list of published components. Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.

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.
