Automatic merge from submit-queue Supports 'ensure exist' class addon in Addon-manager Fixes #39561, fixes #37047 and fixes #36411. Depends on #40057. This PR splits cluster addons into two categories: - Reconcile: Addons that need to be reconciled (`kube-dns` for instance). - EnsureExists: Addons that need to be exist but changeable (`default-storage-class`). The behavior for the 'EnsureExists' class addon would be: - Create it if not exist. - Users could do any modification they want, addon-manager will not reconcile it. - If it is deleted, addon-manager will recreate it with the given template. - It will not be updated/clobbered during upgrade. As Brian pointed out in [#37048/comment](https://github.com/kubernetes/kubernetes/issues/37048#issuecomment-272510835), this may not be the best solution for addon-manager. Though #39561 needs to be fixed in 1.6 and we might not have enough bandwidth to do a big surgery. @mikedanese @thockin cc @kubernetes/sig-cluster-lifecycle-misc --- Tasks for this PR: - [x] Supports 'ensure exist' class addon and switch to use new labels in addon-manager. - [x] Updates READMEs regarding the new behavior of addon-manager. - [x] Updated `test/e2e/addon_update.go` to match the new behavior. - [x] Go through all current addons and apply the new labels on them regarding what they need. - [x] Bump addon-manager and update its template files.
Kubernetes
Introduction
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications. Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF).
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.

Code of Conduct
The Kubernetes community abides by the CNCF code of conduct. Here is an excerpt:
As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
Community
Do you want to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented?. If you are a company, you should consider joining the CNCF. For details about who's involved in CNCF and how Kubernetes plays a role, read the announcement. For general information about our community, see the website community page.
- Join us on social media (Twitter, Google+) and read our blog.
- Ask questions and help answer them on Slack or Stack Overflow.
- Attend our key events (kubecon, cloudnativecon, weekly community meeting).
- Join a Special Interest Group (SIG).
Contribute
If you're interested in being a contributor and want to get involved in developing Kubernetes, get started with this reading:
- The community expectations
- The contributor guidelines
- The Kubernetes Developer Guide
You will then most certainly gain a lot from joining a SIG, attending the regular hangouts as well as the community meeting.
If you have an idea for a new feature, see the Kubernetes Features repository for a list of features that are coming in new releases as well as details on how to propose one.
Building Kubernetes for the impatient
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
While there are many different channels that you can use to get hold of us (Slack, Stack Overflow, Issues, Forums/Mailing lists), you can help make sure that we are efficient in getting you the help that you need.
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. We don't bite!
