kind

Please see Our Documentation 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 (1.11+) and docker installed GO111MODULE="on" go get sigs.k8s.io/kind@v0.9.0 && kind create cluster is all you need!

kind consists of:

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

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.

You can install kind with GO111MODULE="on" go get sigs.k8s.io/kind@v0.9.0.

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 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 Mac & Linux:

curl -Lo ./kind "https://kind.sigs.k8s.io/dl/v0.9.0/kind-$(uname)-amd64"
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind

On Mac via Homebrew:

brew install kind

On Windows:

curl.exe -Lo kind-windows-amd64.exe https://kind.sigs.k8s.io/dl/v0.9.0/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:

kind create cluster

To delete your cluster use:

kind delete cluster

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:
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 or run kind [command] --help
