Hi. I setup Discourse with Docker 1.6.2 (build 7c8fca2). It tried on my localhost first, then did in production server. On my localhost, from container I can see /shared folder, while in production server, I cannot find.
```plaintext
$ ./launcher enter app
root@prodhk-app:/var/lib/docker/aufs/mnt/c97af5f16febf4ae5e0f01a47750381373f3003f0fad79eddab6b89074a7a389# ls /
bin home lib64 nonexistent run sys vmlinuz
boot initrd.img lost+found opt sbin tmp vmlinuz.old
dev initrd.img.old media proc selinux usr
etc lib mnt root srv var
```
How can I solve this? I need the shared folder to backup the database.

Different location on host and container

Excuse me. I don’t understand what you mean.
The config means that the folder `/var/discourse/shared/standalone` in host will be mounted as `/shared` in container. But as you can see in my demonstration, after enter the container, I list directory at `/` but don’t see `shared`.
I also try
`cd /shared`
but no working.

This is my container config: [http://pastie.org/10244604](http://pastie.org/10244604)
This is the command generated when I run `./launch start app`

(I excluded the detail related to SMTP config)
— Update 1 ----
I can see the `shared` folder in immediate current folder after entering the container, which has very long path, but not in “/”
```plaintext
$ ./launcher enter app
root@prodhk-app:/var/lib/docker/aufs/mnt/7c7f4a00525254ad0eb2ab5f745113a54ada0c9b05fa07761299bed4891ea19c# pwd
/var/lib/docker/aufs/mnt/7c7f4a00525254ad0eb2ab5f745113a54ada0c9b05fa07761299bed4891ea19c
root@prodhk-app:/var/lib/docker/aufs/mnt/7c7f4a00525254ad0eb2ab5f745113a54ada0c9b05fa07761299bed4891ea19c# ls
bin dev home lib64 mnt proc root sbin src sys usr
boot etc lib media opt pups run shared srv tmp var
root@prodhk-app:/var/lib/docker/aufs/mnt/7c7f4a00525254ad0eb2ab5f745113a54ada0c9b05fa07761299bed4891ea19c# ls /
bin etc initrd.img.old lost+found nonexistent root selinux tmp vmlinuz
boot home lib media opt run srv usr vmlinuz.old
dev initrd.img lib64 mnt proc sbin sys var
```
But this “shared” folder doesn’t contains any subfolder, such as `postgres_backup`, `uploads`…
- Another issue, may be related to this, is that some files of Discourse are changed the name:

The `reply-post.png` is changed to `reply-post-2x.png`. This makes images in our forum broken.
---- Update 2
I can access `/shared` folder if I use `./launcher ssh app` to enter the container.
