Automatic merge from submit-queue (batch tested with PRs 46441, 43987, 46921, 46823, 47276) kubelet/network: report but tolerate errors returned from GetNetNS() v2 Runtimes should never return "" and nil errors, since network plugin drivers need to treat netns differently in different cases. So return errors when we can't get the netns, and fix up the plugins to do the right thing. Namely, we don't need a NetNS on pod network teardown. We do need a netns for pod Status checks and for network setup. V2: don't return errors from getIP(), since they will block pod status :( Just log them. But even so, this still fixes the original problem by ensuring we don't log errors when the network isn't ready. @freehan @yujuhong Fixes: https://github.com/kubernetes/kubernetes/issues/42735 Fixes: https://github.com/kubernetes/kubernetes/issues/44307
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.
