init

kubeadm init --config kubeadm-config.yaml --v=5 安装好后 按照提示

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

安装calico

kubectl apply -f https://docs.projectcalico.org/v3.24/manifests/calico.yaml

安装好后可能需要 重启虚拟机
