export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

Optional: To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/rancher/k3s/k3s.yaml $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

export KUBECONFIG="~/.kube/config:/etc/rancher/k3s/k3s.yaml"
