Automatic merge from submit-queue (batch tested with PRs 51677, 53690, 53025, 53717, 53664). 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>. Change --etcd-quorum-read default to true The tested configurations for HA etcd use quorum reads. Defaulting this off causes potential correctness issues in controllers that do live lookups when processing their work queue. Given that, we should default this on. Quorum reads are far more performant on etcd3 than they were on etcd2 xref https://github.com/kubernetes/kubernetes/pull/53662#discussion_r143806500 https://github.com/kubernetes/kubernetes/issues/19902 https://github.com/kubernetes/kubernetes/issues/48865 ```release-note apiserver: --etcd-quorum-read now defaults to true, to ensure correct operation with HA etcd clusters ```
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.
