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>.. dockershim: fine-tune network-ready handling on sandbox teardown and removal If sandbox teardown results in an error, GC will periodically attempt to again remove the sandbox. Until the sandbox is removed, pod sandbox status calls will attempt to enter the pod's namespace and retrieve the pod IP, but the first teardown attempt may have already removed the network namespace, resulting in a pointless log error message that the network namespace doesn't exist, or that nsenter can't find eth0. The network-ready mechanism originally attempted to suppress those messages by ensuring that pod sandbox status skipped network checks when networking was already torn down, but unfortunately the ready value was cleared too early. Also, don't tear down the pod network multiple times if the first time we tore it down, it succeeded. **What this PR does / why we need it**: **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # **Special notes for your reviewer**: **Release note**: ```release-note ``` |

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
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.
