Automatic merge from submit-queue (batch tested with PRs 46734, 46810, 46759, 46259, 46771) OpenAPI aggregation for kube-aggregator This PR implements OpenAPI aggregation layer for kube-aggregator. On each API registration, it tries to download swagger.spec of the user api server. On failure it will try again next time (either on another add or get /swagger.* on aggregator server) up to five times. To merge specs, it first remove all unrelated paths from the downloaded spec (anything other than group/version of the API service) and then remove all unused definitions. Adding paths are straightforward as they won't have any conflicts, but definitions will most probably have conflicts. To resolve that, we would reused any definition that is not changed (documentation changes are fine) and rename the definition otherwise. To use this PR, kube aggregator should have nonResourceURLs (for get verb) to user apiserver. ```release-note Support OpenAPI spec aggregation for kube-aggregator ``` fixes: #43717 |

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.
