kind is a tool for running local Kubernetes clusters using Docker container "nodes".
kind is primarily designed for testing Kubernetes 1.11+, initially targeting the conformance tests.

If you have go and docker installed go get sigs.k8s.io/kind && 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.
• kubetest integration 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 docs/roadmap.md.

Installation and usage

You can install kind with go get sigs.k8s.io/kind. This will put kind in $(go env GOPATH)/bin. You may need to add that directory to your $PATH as shown here if you encounter the error kind: command not found after installation.

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
