Docker卷裝配顯示空目錄與Linux掛載目錄

我有一個linux卷，dev/sdh，安裝在/media/ebs_volume。當我嘗試使用-v /media/ebs_volume:/tmp/foo:ro將其安裝到碼頭集裝箱中時，掛載的目錄/tmp/foo爲空！ ls -al /tmp/foo從容器內部是空的，但主機上有ls -al /media/ebs_volume有東西在裏面。Docker卷裝配顯示空目錄與Linux掛載目錄

[email protected] ~]$ ls -al /media/ebs_volume/ 
total 28 
drwxr-xrwx 4 root  root  4096 Jan 20 21:34 . 
drwxr-xr-x 3 root  root  4096 Jan 29 23:18 .. 
drwx------ 2 root  root  16384 Jan 20 21:29 lost+found 
drwxrwxr-x 3 ec2-user ec2-user 4096 Jan 20 21:38 stuff 
[[email protected] ~]$ docker run -it --rm -v /media/ebs_volume:/tmp/foo:ro nginx ls -al /tmp/foo 
total 4 
drwxr-xr-x 2 root root 4096 Jan 29 23:18 . 
drwxrwxrwt 3 root root 16 Jan 30 17:33 ..

我試着在不同位置的主機上安裝卷，並從主機而不是整個目錄安裝一個特定的文件。如果我從主目錄安裝似乎沒有任何問題的東西。

任何人有任何想法可能發生在這裏或最好的方式來調試呢？

一些修改可能有用的輸出：

[[email protected] ~]$ mount 
proc on /proc type proc (rw,relatime) 
/dev/xvda1 on/type ext4 (rw,noatime,data=ordered) 
/dev/xvdh on /media/ebs_volume type ext4 (rw,relatime,data=ordered) 
...

你有沒有想出解決辦法？我遇到同樣的問題，它會掛載文件夾，但沒有文件！ – Joel

抱歉@Joel。從來沒有找到一個真正乾淨的答案，但我已經提交了一個解決方案解決方法。祝你好運 –

骯髒的解決方案，但我發現，通過docker service restart重新啓動搬運工服務固定這對我來說。

我使用ElasticBeanstalk這個，只是增加了一些commands重新啓動上部署該服務在我.config文件，例如：

... 

commands: 
    ... 
    02-restart-docker: 
     command: service docker restart && docker restart ecs-agent 
    ...

見http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html和https://github.com/docker/docker/issues/5489#issuecomment-73427804
