安装

kubeadm init --kubernetes-version=1.14.2 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.100.111 To start using your cluster, you need to run the following as a regular user: ### master执行 mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config You should now deploy a pod network to the cluster. Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: https://kubernetes.io/docs/concepts/cluster-administration/addons/ Then you can join any number of worker nodes by running the following on each as root: ## node 节点执行 kubeadm join 192.168.100.111:6443 --token ws2hxe.zeq9skej2ppjx4ip \ --discovery-token-ca-cert-hash sha256:abf8f2694f738fcd199aa5bbf99491b0f9248b3750b1df7ba47450bbe9a75f81
