So you mount a volume to a container like so: -v volume:/path/to/target-directory.
I want to do: -v volume/source-directory:/path/to/target-directory. Rather than creating more volumes, I’d rather have one with directories in it that I mount to various places on the container file system.
Is this possible? Google shows no examples AFAICT.
both source and destination can be full paths.
some examples:
-v /etc/localtime:/etc/localtime #mounts a single file in the container
-v volume_example:/mnt/media #creates a new volume
-v /srv/media/tv:/tv #mounts an existing directory
Thanks, but I meant mounting a folder within a volume. So for example:
docker volume create test-volume
mkdir /path/to/test-volume/on/host/new-directory
docker run -dit --name application -v test-volume/new-directory:/path/to/mount/point

Maybe one day.
Yeah, sorry.
If you’re running btrfs, you could always create a subvol somewhere else with your desired config.
A volume is a term that docker uses to designate something like basically a writable image.
You could use symlinks within a container (that’s a bit meh and ugly, depending on what you’re running it could help).
The only quick way I would know of doing anything of that nature would be to bind-mount within the given volume.
…And here might be of assistance.
P.s.-Sackoverflow had a few usefull answers as well.
