建议使用virtualbox6.1进行安装

• 提问者 qq_慕函数1536532 #1

  kubeadm init --kubernetes-version=1.19.3 \
  --apiserver-advertise-address=192.168.2.107 \
  --image-repository registry.aliyuncs.com/google_containers \
  --service-cidr=10.1.0.0/16 \
  --pod-network-cidr=10.244.0.0/16
  
  如果是从节点的话：--apiserver-advertise-address = 从节点的IP 还是 主节点的 IP

  从节点是使用kubeadm join命令，在主节点执行kubeadm token create --print-join-command
