- 已经安装好的集群轮换 ca 证书是比较麻烦的，你可以参照这里的说明进行轮换：https://kubernetes.io/docs/tasks/tls/manual-rotation-of-ca-certificates/
- ca 证书有效期默认是 10 年，其实时间已经很长了
- 如果你的集群还没开始安装，手动签发有效期更长的 ca 证书放置到 master init 节点对应路径，包含
ca.crtfront-proxy-ca.crtetcd.crt以及对应的 key 文件，当执行 kubeadm init 时，它会先检查改路径是否存在有效的 ca 证书，如果存在，那么会优先使用已经存在的ca证书。
