k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker.
k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.
Start a Cluster
- Create a cluster named mycluster with just a single server node:
> k3d cluster create mycluster
- Get the new cluster’s connection details merged into your default kubeconfig (usually specified using the KUBECONFIG environment variable or the default path $HOME/.kube/config) and directly switch to the new context:
> k3d kubeconfig merge mycluster --switch-context
- Use the new cluster with kubectl, e.g.:
> kubectl get svc
Now you have a working Kubernetes cluster running locally using K3d and have proper authentication using kubectl to connect to the cluster you can proceed to Kubernetic Installation guide.
