  help [COMMAND]  # show help text for any command
  completion [bash | zsh | (psh | powershell)]  # generate completion scripts for common shells
  cluster [CLUSTERNAME]  # default cluster name is 'k3s-default'
    create
      --api-port  # specify the port on which the cluster will be accessible (e.g. via kubectl)
      -i, --image  # specify which k3s image should be used for the nodes
      --k3s-agent-arg  # add additional arguments to the k3s agent (see https://rancher.com/docs/k3s/latest/en/installation/install-options/agent-config/#k3s-agent-cli-help)
      --k3s-server-arg  # add additional arguments to the k3s server (see https://rancher.com/docs/k3s/latest/en/installation/install-options/server-config/#k3s-server-cli-help)
      -s, --servers  # specify how many server nodes you want to create
      --network  # specify a network you want to connect to
      --no-hostip # disable the automatic injection of the Host IP as 'host.k3d.internal' into the containers and CoreDN
