Chapter 5

The easiest way to play with volumes is to use the Docker Toolbox as when directly using Docker for Mac or Docker for Windows, then the volumes are stored inside a (somewhat hidden) Linux VM that Docker for Mac/Win uses transparently.

Thus, we suggest the following:

$ docker-machine create --driver virtualbox volume-test
$ docker-machine ssh volume-test

And now that you're inside a Linux VM called volume-test, you can execute the following exercises:

1. To create a named volume run the following command:

 $ docker volume create my-products

2. Execute the following command:

$ docker container run -it --rm \
    -v my-products:/data:ro \
    alpine /bin/sh

3. To get the path on the host for the volume use, for example, this command:

$ docker volume inspect my-products | grep Mountpoint

Which (if using docker-machine and VirtualBox) should result in:
