Environment that needs to be prepared:
6 centos7 devices:
192.168.136.167 master01
192.168.136.168 node1
192.168.136.169 node2
192.168.136.170 master02
192.168.136.171 lb1
192.168.136.172 lb2
VIP:192.168.1.100
The steps of the experiment:
1: self-signed ETCD certificate
2:ETCD deployment
3:Node install docker
4:Flannel deployment (write subnet to etcd first)
-master-
5: self-signed APIServer certificate
6: deploy APIServer components (token,csv)
7: deploy controller-manager (specify apiserver certificate) and scheduler components
-node-
8: generate kubeconfig (bootstrap,kubeconfig and kube-proxy.kubeconfig)
9: deploy kubelet components
10: deploy kube-proxy components
-join the cluster-
11:kubectl get csr & & kubectl certificate approve permit method certificate to join the cluster
12: add a node node
13: view the kubectl get node node
