Fig apparently not using volume_from on mysql service

I'm trying to setup a very simple setup of a mysql database using a data-container as repository using Fig.sh and Docker.

The code below is self-explanatory:

web:
  build: .
  command: php -S 0.0.0.0:8000 -t /code
  ports:
    - "8000:8000"
  links:
    - db
  volumes:
    - .:/code
dbdata:
  image: busybox
  command: /bin/sh
  volumes:
    - /var/lib/mysql
db:
  image: mysql
  volumes_from:
    - dbdata
  environment:
    MYSQL_DATABASE: database
    MYSQL_ROOT_PASSWORD: rootpasswd

For some reason, if I run a command fig run --rm dbdata /bin/sh and then I cd into the directory /var/lib/mysql. The folder is empty. If I run fig run --rm db /bin/sh and cd into /var/lib/mysql the database is being created there.

What am I doing wrong here? And taking advantage of the question, is this the correct setup or I should let the data inside the mysql container?

Thanks.

Docs for how to mount a data volume in Docker: https://docs.docker.com/userguide/dockervolumes/

You are missing the local path on the host
volumes:
- SOME_LOCAL_PATH_ON_HOST:/var/lib/mysql

To answer your question on if you should host the data in the docker image: I would say any data store that you lose would cause more than service degradation you should protect against. You can accomplish this through clustering (multiple containers across multiple physical hosts in MM or MS setup) and/or data volumes from the local host. I would recommend using a volume and clustering if needed.

I read on the docs (http://www.fig.sh/yml.html) on volumes section that you can do something like this.

volumes:
 - /var/lib/mysql
 - cache/:/tmp/cache
 - ~/configs:/etc/configs/:ro

@sge-babrams So, this is a typo?

[thomasleveil]

I believe your issue is about volumes_from which is ignored when using fig run while it is working as expected when using fig up. I'm not sure there is anything wrong with volumes.

[sge-babrams]

@wlepinski takeing a closer look that seems fine.

[sirwolfgang]

I just ran into this issue; Is there any reason that fig run ignores volumes_from? That seems like a major bug to me.

It's being worked on in #686, I think that is a bug

[dnephin]

I believe this was fixed by #1076
