Automatic merge from submit-queue Implement kubeadm bootstrap token management Creates bootstrap tokens as secrets per the specification in #30707 _WARNING_: These are not currently hooked up to the discovery service or the token it creates. Still TODO: - [x] delete tokens - [x] merge with #35144 and adopt it's testing approach - [x] determine if we want wholesale json output & templating like kubectl (we do not have an API object with the data we want here) may require a bit of plumbing. - [x] allow specifying a token duration on the CLI - [x] allow configuring the default token duration - [x] hook up the initial token created during init Sample output: ``` (root@centos1 ~) $ kubeadm token create Running pre-flight checks <cmd/token> Token secret created: f6dc69.c43e491752c4a0fd (root@centos1 ~) $ kubeadm token create Running pre-flight checks <cmd/token> Token secret created: 8fad2f.e7b78c8a5f7c7b9a (root@centos1 ~) $ kubeadm token list Running pre-flight checks ID TOKEN EXPIRATION 44d805 44d805.a4e78b6cf6435e33 23h 4f65bb 4f65bb.d006a3c7a0e428c9 23h 6a086e 6a086e.2ff99f0823236b5b 23h 8fad2f 8fad2f.e7b78c8a5f7c7b9a 23h f6dc69 f6dc69.c43e491752c4a0fd 23h f81653 f81653.9ab82a2926c7e985 23h ``` |

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.
Are you ...
- 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!
