Automatic merge from submit-queue Skip inspecting pod network if unknown namespace **What this PR does / why we need it**: If we fail to determine the network namespace of a container we still try to inspect the state - even though there is no way for it to succeed. This leads to errors like: > NetworkPlugin cni failed on the status hook for pod "X": Unexpected command output nsenter: cannot open : No such file or directory Instead, if we cannot determine the network namespace, we should just exit with a (hopefully) more clear error message. I left the wording as assuming a terminated pod, based on: https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/dockershim/helpers.go#L208-L211 ref: https://github.com/kubernetes-incubator/bootkube/issues/475 https://github.com/coreos/coreos-kubernetes/issues/856
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.
