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 1.16+ and docker or podman installed go install sigs.k8s.io/kind@v0.21.0 && kind create cluster is all you need!
kind consists of:
- Go packages implementing cluster creation, image build, etc.
- A command line interface (
kind) built on these packages. - Docker image(s) written to run systemd, Kubernetes, etc.
kubetestintegration also built on these packages (WIP)
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 go install sigs.k8s.io/kind@v0.21.0.
NOTE: please use the latest go to do this. KIND is developed with the latest stable go, see .go-version for the exact version we're using.
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 Linux:
# For AMD64 / x86_64
[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.21.0/kind-$(uname)-amd64
# For ARM64
[ $(uname -m) = aarch64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.21.0/kind-$(uname)-arm64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind
On macOS via Homebrew:
brew install kind
On macOS via MacPorts:
sudo port selfupdate && sudo port install kind
On macOS via Bash:
# For Intel Macs
[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.21.0/kind-darwin-amd64
# For M1 / ARM Macs
[ $(uname -m) = arm64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.21.0/kind-darwin-arm64
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind
On Windows:
curl.exe -Lo kind-windows-amd64.exe https://kind.sigs.k8s.io/dl/v0.21.0/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
