k3s in docker
k3s is the lightweight Kubernetes distribution by Rancher: k3s-io/k3s
k3d creates containerized k3s clusters. This means, that you can spin up a multi-node k3s cluster on a single machine using docker.
Note: k3d is a community-driven project but it's not an official Rancher (SUSE) product. Sponsoring: To spend any significant amount of time improving k3d, we rely on sponsorships:

- 'make install-tools' to make sure required go packages are installed
- Inside the repo run one of the following commands
make buildto build for your current systemgo installto install it to yourGOPATH(Note: this will give you unreleased/bleeding-edge changes)make build-crossto build for all systems
Usage
Check out what you can do via k3d help or check the docs @ k3d.io
Example Workflow: Create a new cluster and use it with kubectl
k3d cluster create CLUSTER_NAMEto create a new single-node cluster (= 1 container running k3s + 1 loadbalancer container)- [Optional, included in cluster create]
k3d kubeconfig merge CLUSTER_NAME --kubeconfig-switch-contextto update your default kubeconfig and switch the current-context to the new one - execute some commands like
kubectl get pods --all-namespaces k3d cluster delete CLUSTER_NAMEto delete the default cluster

History
This repository is based on @zeerorg's zeerorg/k3s-in-docker, reimplemented in Go by @iwilltry42 in iwilltry42/k3d, which got adopted by Rancher in rancher/k3d and was now moved into its own GitHub organization at k3d-io/k3d.
