These three options are the ones from logs.AddFlags which are not deprecated. Therefore it makes sense to make them available also via the configuration file support in the one command which currently supports that (kubelet). Long-term, all commands should use LoggingConfiguration, either with a configuration file (as in kubelet) or via flags (kube-scheduler, kube-apiserver, kube-controller-manager). Short-term, both approaches have to be supported. As the majority of the commands only use logs.AddFlags, that function by default continues to register the flags and only leaves that to Options.AddFlags when explicitly requested. A drive-by bug fix is done for log flushing: the periodic flushing called klog.Flush and therefore missed explicit flushing of the newer logr backend. This bug was never present in any release Kubernetes and therefore the fix is not submitted in a separate PR. |

Kubernetes (K8s)
Kubernetes, also known as K8s, is an open source system for managing containerized applications across multiple hosts. It provides 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 your company 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 K8s
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To use Kubernetes code as a library in other applications, see the list of published components.
Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.
To start developing K8s
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.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make
You have a working Docker environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
For the full story, 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.
