Automatic merge from submit-queue Add namespaced role to inspect particular configmap for delegated authentication Builds on https://github.com/kubernetes/kubernetes/pull/41814 and https://github.com/kubernetes/kubernetes/pull/41922 (those are already lgtm'ed) with the ultimate goal of making an extension API server zero-config for "normal" authentication cases. This part creates a namespace role in `kube-system` that can *only* look the configmap which gives the delegated authentication check. When a cluster-admin grants the SA running the extension API server the power to run delegated authentication checks, he should also bind this role in this namespace. @sttts Should we add a flag to aggregated API servers to indicate they want to look this up so they can crashloop on startup? The alternative is sometimes having it and sometimes not. I guess we could try to key on explicit "disable front-proxy" which may make more sense. @kubernetes/sig-api-machinery-misc @ncdc I spoke to @liggitt about this before he left and he was ok in concept. Can you take a look at the details?
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.

- Interested in learning more about using Kubernetes?
- See our documentation on kubernetes.io.
- Try our interactive tutorial.
- Take a free course on Scalable Microservices with Kubernetes.
- Interested in developing the core Kubernetes code base, developing tools using the Kubernetes API or helping in anyway possible? Keep reading!
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!
