1.kube-controller-manager顯示不健康，報如下錯誤
kube-controller-manager[3234]: I0723 10:26:35.027041 3234 log.go:172] http: TLS handshake error from 127.0.0.1:40108: tls: first record does not look like a TLS handshake
2.解決方案
修改/etc/systemd/system/kube-controller-manager.service，將
--port=0
--secure-port=10252
刪除
3.systemctl daemon-reload
service kube-controller-manager restart
4.參考文檔
