How do I backup data from MySQL container into a shared volume?
<p>If I'm working with a containerized MySQL database that wasn't originally run with shared volume options, what's the easiest way to sort of externalize the data? Is there still a way to modify the container so that it shares its data with the Docker host in a specified directory?</p>

<p>Note: if you're still having problems with this question, please comment so I can improve it further.</p>
