k8s 生成kubelet bootstrap文件

时间:2021-04-21 16:46:19

接着上面的博客继续写

  pwd

  /etc/kubernetes

  kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/ssl/ca.pem --server=https://192.168.1.71:6443 --kubeconfig=bootstrap.kubeconfig

  设置k8s bootstrap.kubeconfig token

  kubectl config set-credentials kubelet-bootstrap --token=`awk -F ',' '{print $1}' token.csv` --kubeconfig=bootstrap.kubeconfig

  如果上面的执行有错误 最好文件都删除再执行

  生成默认的上下文参数

  kubectl config set-context default --cluster=kubernetes --user=kubelet-bootstrap --kubeconfig=bootstrap.kubeconfig

  切换上下文

  kubectl config use-context default --kubeconfig=bootstrap.kubeconfig

  cat bootstrap.kubeconfig

  

apiVersion: v1
clusters:
- cluster:
    certificate-authority: ssl/ca.pem
    server: https://192.168.1.71:6443

  通过命令行设置的配置文件 证书是相对路径 也可以直接修改成绝对路径
