Docker 本身DNS是不穩定的

再分享早上碰到docker穩定度問題，docker內到外網是靠本機的iptables做Nat出去，早上就發現運行很久的docker container，突然不送資料到ELK，一查發現DNS掛了，這之前也碰到幾次了，基本上不是中心DNS掛了，而且Docker本身架構的DNS掛了，基本上只要重啟docker service後就正常，無需對主機重啟，而重啟docker service是一件很嚴重的事情，因為上面所有的服務都會一併被下線，之後還要在把運行的服務全部重新上線… 也許我的理解是錯誤，但只能以目前的情況來判斷，也許是iptables nat轉換的問題，但本機沒有重開機，理論上就沒有這個問題才是。
