## [k3s in docker](https://k3d.io)



k3s is the lightweight Kubernetes distribution by Rancher: [k3s-io/k3s](https://github.com/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:

2. [Optional, included in cluster create] `k3d kubeconfig merge CLUSTER_NAME --kubeconfig-switch-context` to update your default kubeconfig and switch the current-context to the new one

3. execute some commands like `kubectl get pods --all-namespaces`

4. `k3d cluster delete CLUSTER_NAME` to delete the default cluster
