I'm trying to mount a single file from a Docker volume in a container when using "docker run".

I've been able to mount an entire volume as a directory, e.g:

docker run -v my_volume:/root/volume my_container 

I've also mounted single files from the physical machine, e.g:

docker run -v /usr/local/bin/docker:/usr/local/bin/docker 

Is there a way?

  • Sure you can https://docs.docker.com/engine/tutorials/dockervolumes/#/mount-a-host-file-as-a-data-volume, but I've been having the same issue – mbk Sep 08 '16 at 23:46

Is there a way always destination path/file doesn't exist in the container, if you've created a named volume and a bind to its directory (similar to deprecated volumes_from)

docker run -v /var/lib/docker/volumes/my_volume/_data/MY_FILE.txt:/destination_folder/MY_FILE.txt

That's why when you create a named volume and run a service/container with docker run -v my_volume:/root/volume my_container, data is stored in /var/lib/docker/volumes/my_volume/_data
