If the file does not exist on the host side, a dir is created and that is what is mounted in.
Also note that host mounts are relative to the docker daemon, not the docker client.

If the file does not exist on the host side

But the files are exists, I doublechecked it.

Also note that host mounts are relative to the docker daemon, not the docker client.

Could you give me a link to read about it or give an example?
Thanks.

@animir I don't know what the values of your env vars are, but the paths provided must be absolute and the paths must be there on the host where the docker daemon is running.

Yes, I checked it, all right.
Any other ideas?

[cpuguy83]

@animir That's all it would be.
If the docker daemon does not see files there, it creates dirs and mounts dirs.
For compose, if you are using relative paths, you must use ./ as a prefix, otherwise you will get a named volume instead of a bind mounted path.

@animir looking at your setup, I see you're using boot2docker (Kernel Version: 4.1.19-boot2docker), but your host is Linux? (Linux Setori 3.13.0-83-generic); are you running VirtualBox on linux to run boot2docker? If so; did you set up VirtualBox filesharing to give the VirtualBox VM (in which the daemon runs) access to the files on your Linux host?

Any reason you're running docker inside a VM, and not directly on the Linux host?

[animir]

Thanks, @cpuguy83 and @thaJeztah
You both were right.
I didn't configure VirtualBox VM as well, hence docker didn't see any files and linked them as folders.
