Add an option for turning on/off compaction from apiserver in etcd3 mode …erver **What this PR does / why we need it**: This commit adds an option for controlling request of compaction to etcd3 from apiserver. There is a situation that apiserver cannot fully own its etcd cluster (e.g. sharing it with canal). In such a case, apiserver should have limited access in terms of etcd's auth functionality so it don't have a privilege to issue compaction requests. It means that the compaction requests should be issued by other component and apiserver's compaction requests are needless. For such use cases, this commit adds a new flag storagebackend.Config.DoCompaction. If the flag is true (default), apiserver issues the compaction requests like current behaviour. If it is false, apiserver doesn't issue the requests. **Related issue (etcd)** https://github.com/coreos/etcd/issues/8458 /cc @xiang90 @struz **Release note:** ```release-note Add --etcd-compaction-interval to apiserver for controlling request of compaction to etcd3 from apiserver. ``` |

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.
