Push the kubeconfig file

[root@master kubeconfig] # scp bootstrap.kubeconfig kube-proxy.kubeconfig root@192.168.142.132:/opt/kubernetes/cfg/ [root@master kubeconfig] # scp bootstrap.kubeconfig kube-proxy.kubeconfig root@192.168.142.136:/opt/kubernetes/cfg/

Write kubectl to the environment variable

[root@master kubeconfig] # echo "export PATH=\ $PATH:/opt/kubernetes/bin/" > > / etc/profile [root@master kubeconfig] # source / etc/profile create bootstrap role permission for apiserver request signature

The most important thing! There is no basic end)

[root@master kubeconfig] # kubectl create clusterrolebinding kubelet-bootstrap\-- clusterrole=system:node-bootstrapper\-- user=kubelet-bootstrapnode side (all nodes have different addresses, all remaining steps are the same) install Kubelet

Specify node nodes IP and DNS as global variables (different node node variables need to be changed)

You can also change it directly in the configuration file without setting the variable.

[root@node1 bin] # export NODE_ADDRESS= "192.168.142.136" [root@node1 bin] # export DNS_SERVER_IP= "192.168.142.2"

Create a kubelet profile

[root@node1 ~] # cat
