Docker how to get volumes used by a container

Question

I'm using Docker version 1.10. How can I get the volumes used by a container?

I know I can get the containers by:

docker ps

And I can inspect them with:

docker inspect $containerID

I also know that the volume API is available, so I can also do:

docker volume ls

and

docker volume inspect $volumeID

But I can't find any link information between them. What should I use?

You can get the detail volume information of a container by

docker inspect --format="{{.Mounts}}" $containerID

If I create a volume named "volumehello", and start a container named "hello" which use "volumehello":

docker volume create --name volumehello
docker run -it -d --name=hello -v volumehello:/tmp/data hello-world

Then we can get the volume information of "hello" container by running:

docker inspect --format="{{.Mounts}}" hello

We will get:

[{volumehello /var/lib/docker/volumes/volumehello/_data /tmp/data local z true rprivate}]

• volumehello is the volume name
• /var/lib/docker/volumes/volumehello/_data is the host location of the volume
• /tmp/data is the mapped location of the volume within the container
