¿What is data volume used for?

I see that everything goes inside /ghost-override

What am I missing?

Thanks

Are you referring to "content/data/"? If yes, this is for the SQLite database file of your blog, to make it persisent.

config.js: your blog's config file, to override defaults.
content/images/: images you upload to your blog will be save here, again to make them persistent.
content/themes/: if you want to use a cusom theme, you just have to put it here so you can find it in your blog settings.

This make the container stateless, so even when the containet is removed, your database, images, themes, configuration will stay on the host.

@YoussefKababe is it possible to use a DB other than sqlite for scalability?
