嗨，我已經安裝並啓動碼頭集裝箱。當我進入這個容器和做的ifconfig，這是我得到：不能ping我的碼頭集裝箱外的主機

我可以完美ping通這些地址形成主機（eth0和它的虛擬IPS）
在主機上，這是ifconfig輸出

現在我嘗試ping其他機器的容器不會忽略（10.50.0.2，10.50.1.1，...）都在同一個網絡中的主機和路由加入到他們使用主機作爲gw來訪問10.50.0.0/16網絡，但我無法ping泊塢器聯繫iner IP。我使用的是docker 17 ce和ubuntu 16.
爲什麼你需要首先ping它們？ – Grimmy
因爲我想ssh容器，不能，我使用端口10050，並通過碼頭運行啓動容器-p 10050：10050，但不能ssh用戶@主機-p 10050，所以我ping。 – user2133558
您正在容器中的端口10050上運行sshd？ – Grimmy
