A prepopulated mysql container ?
================================
Yeah why not, i like my test faster :D
But how ?
---------
The mysql/mariadb container image contain an init script that will execute everything in `/docker-entrypoint-initdb.d/`
see `Initializing a fresh instance` @ https://hub.docker.com/_/mariadb/
So let's run this initialization in a multi-stage build and copy the initialized DB in the new image :D
(see comments in dockerfile for details of the hack)
Try it!
======
Clone this, then...
```
}> docker build --tag my-prepopulated-image .
...
}> docker run -d --rm --name my-container my-prepopulated-image
...
}> docker logs my-container
(there was is initialization here, therefore we win)
