# Contributing guidelines

|
|
|
Want to hack on Kubernetes? Yay!
|
|
|
|
## Developer Guide
|
|
|
|
We have a [Developer's Guide](docs/devel/README.md) that outlines everything
|
|
you need to know from setting up your dev environment to how to get faster Pull
|
|
Request reviews. If you find something undocumented or incorrect along the way,
|
|
please feel free to send a Pull Request.
|
|
|
|
## Filing issues
|
|
|
|
If you have a question about Kubernetes or have a problem using it, please
|
|
start with the [troubleshooting guide](http://kubernetes.io/docs/troubleshooting/). If that
|
|
doesn't answer your questions, or if you think you found a bug, please [file an
|
|
issue](https://github.com/kubernetes/kubernetes/issues/new).
|
|
|
|
## How to become a contributor and submit your own code
|
|
|
|
### Contributor License Agreements
|
|
|
|
We'd love to accept your patches! Before we can take them, we have to jump a
|
|
couple of legal hurdles.
|
|
|
|
The Cloud Native Computing Foundation (CNCF) CLA [must be signed](https://github.com/kubernetes/community/blob/master/CLA.md) by all contributors.
|
|
Please fill out either the individual or corporate Contributor License
|
|
Agreement (CLA).
|
|
|
|
Once you are CLA'ed, we'll be able to accept your pull requests. For any issues that you face during this process,
|
|
please add a comment [here](https://github.com/kubernetes/kubernetes/issues/27796) explaining the issue and we will help get it sorted out.
|
|
|
|
***NOTE***: Only original source code from you and other people that have
|
|
signed the CLA can be accepted into the repository. This policy does not
|
|
apply to [third_party](third_party/) and [vendor](vendor/).
|
|
|
|
### Finding Things That Need Help
|
|
|
|
If you're new to the project and want to help, but don't know where to start,
|
|
we have a semi-curated list of issues that have should not need deep knowledge
|
|
of the system. [Have a look and see if anything sounds
|
|
interesting](https://github.com/kubernetes/kubernetes/issues?q=is%3Aopen+is%3Aissue+label%3Ahelp-wanted).
|
|
|
|
Alternatively, read some of the many docs on the system, for example [the
|
|
architecture](docs/design/architecture.md), and pick a component that seems
|
|
interesting. Start with `main()` (look in the [cmd](cmd/) directory) and read
|
|
until you find something you want to fix. The best way to learn is to hack!
|
|
There's always code that can be clarified and variables or functions that can
|
|
be renamed or commented.
|
|
|
|
### Contributing A Patch
|
|
|
|
If you're working on an existing issue, such as one of the `help-wanted` ones
|
|
above, simply respond to the issue and express interest in working on it. This
|
|
helps other people know that the issue is active, and hopefully prevents
|
|
duplicated efforts.
|
|
|
|
If you want to work on a new idea of relatively small scope:
|
|
|
|
1. Submit an issue describing your proposed change to the repo in question.
|
|
1. The repo owners will respond to your issue promptly.
|
|
1. If your proposed change is accepted, and you haven't already done so, sign a
|
|
Contributor License Agreement (see details above).
|
|
1. Fork the repo, develop, and test your changes.
|
|
1. Submit a pull request.
|
|
|
|
If you want to work on a bigger idea, we STRONGLY recommend that you start with
|
|
some bugs or smaller features. We have a [feature development
|
|
process](https://github.com/kubernetes/features/blob/master/README.md), but
|
|
navigating the Kubernetes system as a newcomer can be very challenging.
|
|
|
|
### Downloading the project
|
|
|
|
There are a few ways you can download this code. You must download it into a
|
|
GOPATH - see [golang.org](https://golang.org/doc/code.html) for more info on
|
|
how Go works with code. This project expects to be found at the Go package
|
|
`k8s.io/kubernetes`.
|
|
|
|
1. You can `git clone` the repo. If you do this, you MUST make sure it is in
|
|
the GOPATH as `k8s.io/kubernetes` or it may not build. E.g.: `git clone
|
|
https://github.com/kubernetes/kubernetes $GOPATH/src/k8s.io/kubernetes`
|
|
1. You can use `go get` to fetch the repo. This will automatically put it into
|
|
your GOPATH in the right place. E.g.: `go get -d k8s.io/kubernetes`
|
|
1. You can download an archive of the source. If you do this, you MUST make
|
|
sure it is unpacked into the GOPATH as `k8s.io/kubernetes` or it may not
|
|
build. See [rel.k8s.io](http://rel.k8s.io) for a list of available releases.
|
|
|
|
### Building the project
|
|
|
|
There are a few things you need to build and test this project:
|
|
|
|
1. `make` - the human interface to the Kubernetes build is `make`, so you must
|
|
have this tool installed on your machine. We try not to use too many crazy
|
|
features of `Makefile`s and other tools, so most commonly available versions
|
|
should work.
|
|
1. `docker` - some parts of the build/test system depend on `docker`. You
|
|
need a relatively recent version of Docker installed, and available to you.
|
|
1. `go` - Kubernetes is written in Go (aka golang), so you need a relatively
|
|
recent version of the [Go toolchain](https://golang.org/dl/) installed.
|
|
While Linux is the primary platform for Kubernetes, it should compile on a
|
|
Mac, too. Windows is in progress.
|
|
|
|
To build Kubernetes, simply type `make`. This should figure out what it needs
|
|
to do and not need any input from you. If you want to just build a subset of
|
|
code, you can pass the `WHAT` variable to `make`: e.g. `make
|
|
WHAT="cmd/kubelet"`.
|
|
|
|
To run basic tests, simply type `make test`. This will run all of the unit
|
|
tests in the project. If you want to just test a subset of the project, you
|
|
can pass the `WHAT` variable to `make`: e.g. `make test WHAT=pkg/kubelet`.
|
|
|
|
### Protocols for Collaborative Development
|
|
|
|
Please read [this doc](docs/devel/collab.md) for information on how we're
|
|
running development for the project. Also take a look at the [development
|
|
guide](docs/devel/development.md) for information on how to set up your
|
|
environment, run tests, manage dependencies, etc.
|
|
|
|
### Adding dependencies
|
|
|
|
If your patch depends on new packages, add that package with
|
|
[`godep`](https://github.com/tools/godep). Follow the [instructions to add a
|
|
dependency](docs/devel/development.md#godep-and-dependency-management).
|
|
|
|
### Community Expectations
|
|
|
|
Please see our [expectations](docs/devel/community-expectations.md) for members
|
|
of the Kubernetes community.
