# Please see [Our Documentation](https://kind.sigs.k8s.io/docs/user/quick-start/) for more in-depth installation etc.

kind is a tool for running local Kubernetes clusters using Docker container "nodes".
kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI.

If you have [go] \([1.17+][go-supported]) and [docker] installed `go install sigs.k8s.io/kind@{{< stableVersion >}} && kind create cluster` is all you need!

For older versions use `GO111MODULE="on" go get sigs.k8s.io/kind@{{< stableVersion >}}`.

![](site/static/images/kind-create-cluster.png)

kind consists of:
- Go [packages][packages] implementing [cluster creation][cluster package], [image build][build package], etc.
- A command line interface ([`kind`][kind cli]) built on these packages.
- Docker [image(s)][images] written to run systemd, Kubernetes, etc.
- [`kubetest`][kubetest] integration also built on these packages (WIP)

kind bootstraps each "node" with [kubeadm][kubeadm]. For more details see [the design documentation][design doc].

**NOTE**: kind is still a work in progress, see the [1.0 roadmap].

## Installation and usage

For a complete [install guide] see [the documentation here][install guide].

You can install kind with `GO111MODULE="on" go get sigs.k8s.io/kind@v0.12.0`.

**NOTE**: please use the latest go to do this, ideally go 1.13 or greater.

**NOTE**: `go get` should not be run from a Go [modules] enabled project directory,
as go get inside a modules enabled project updates dependencies / behaves differently. Try for example `cd $HOME` first.

This will put `kind` in `$(go env GOPATH)/bin`. If you encounter the error
`kind: command not found` after installation then you may need to either add that directory to your `$PATH` as
shown [here](https://golang.org/doc/code.html#GOPATH) or do a manual installation by cloning the repo and run
`make build` from the repository.

Without installing go, kind can be built reproducibly with docker using `make build`.

Stable binaries are also available on the [releases] page. Stable releases are
generally recommended for CI usage in particular.
To install, download the binary for your platform from "Assets" and place this
into your `$PATH`:

On Linux:

```console
curl -Lo ./kind "https://kind.sigs.k8s.io/dl/v0.12.0/kind-$(uname)-amd64"
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind
```

On macOS via Homebrew:

```console
brew install kind
```

On macOS via MacPorts:

```console
sudo port selfupdate && sudo port install kind
```

On macOS via Bash:

```console
curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.12.0/kind-darwin-amd64
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind
```

On Windows:

```powershell
curl.exe -Lo kind-windows-amd64.exe https://kind.sigs.k8s.io/dl/v0.12.0/kind-windows-amd64
Move-Item .\kind-windows-amd64.exe c:\some-dir-in-your-PATH\kind.exe

# OR via Chocolatey (https://chocolatey.org/packages/kind)
choco install kind
```

To use kind, you will need to [install docker].
Once you have docker running you can create a cluster with:

```console
kind create cluster
```

To delete your cluster use:

```console
kind delete cluster
```

<!--TODO(bentheelder): improve this part of the guide-->
To create a cluster from Kubernetes source:
- ensure that Kubernetes is cloned in `$(go env GOPATH)/src/k8s.io/kubernetes`
- build a node image and create a cluster with:
```console
kind build node-image
kind create cluster --image kindest/node:latest
```

Multi-node clusters and other advanced features may be configured with a config
file, for more usage see [the docs][user guide] or run `kind [command] --help`
