You can now join any number of machines by running the following on each node: kubeadm join --token 42354d.e1fb733ed0c9a932 192.168.1.107
然后在子节点上使用 join 命令加入集群即可
kubeadm join --token 42354d.e1fb733ed0c9a932 192.168.1.107
最后稍等片刻在 master 上 get nodes 即可查看，如果想让 master 也运行 pod，只需在 master 上运行 kubectl taint nodes --all dedicated- 即可
➜ ~ kubectl get nodes NAME STATUS AGE master Ready 1m node1 Ready 1m node2 Ready 1m
2.5、创建 Pod 网络创建好集群后，为了能让容器进行跨主机通讯还要部署 Pod 网络，这里使用官方推荐的 weave 方式，也可以采用 flannel，以下为 weave 示例
# 在 master 上执行 kubectl apply -f https://git.io/weave-kube
