K3d cluster create

k3d cluster create

Create a new cluster

Synopsis

Create a new k3s cluster with containerized nodes (k3s in docker). Every cluster will consist of one or more containers: - 1 (or more) server node container (k3s) - (optionally) 1 loadbalancer container as the entrypoint to the cluster (nginx) - (optionally) 1 (or more) agent node containers (k3s)
