k8s etcd 連接錯誤

今天在用代碼連接k8s內部的etcd的時候，遇到了下面這個錯誤，全網搜索也沒有相似的：

{"level":"warn","ts":"2020-04-19T19:59:50.119+0800","caller":"clientv3/retry_interceptor.go:62","msg":"retrying of unary invoker failed","target":"endpoint://client-73d50550-933e-4101-a717-e64553b58c77/192.168.226.128:2379","attempt":0,"error":"rpc error: code = DeadlineExceeded desc = latest balancer error: all SubConns are in TransientFailure, latest connection error: connection closed"}

在put 插入值得時候就斷開連接了，如果不用k8s集羣內部得etcd就沒得問題，於是猜測是k8s採用的是https，需要一些認證。大家如果有什麼好的解決方法，歡迎關注加羣討論。
