Adjust defaults of audit webhook backends This PR: - increases the default buffer size to contain at lease on the order of magnitude audit events than it's possible to have simultaneous requests (500 AFAIR) - increase the default batch size. From our load tests .95 size of the log entry is under 2.5KB, therefore 400 entry will sum up to ~1MB request, which sounds reasonable - increase the initial backoff size. AFAIU, if the initial value is zero, all retries will be used in under 15 seconds (with 0.2 jitter and 1.5 factor), while the backend or a proxy can be unavailable for some reason for 30 seconds and more. - add throttling to the batching audit webhook A PR to make these parameters configurable will follow-up @hzxuzhonghu implemented throttling part of this PR ```release-note Adjust batching audit webhook default parameters: increase queue size, batch size, and initial backoff. Add throttling to the batching audit webhook. Default rate limit is 10 QPS. ``` /cc @sttts @tallclair @CaoShuFeng @ericchiang @piosz |

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.
