move from links to networks

[icyflame]

links is deprecated in Docker: https://docs.docker.com/network/links/

This is the network diagram (the arrows represent the old links, and the annotations near the arrows represent the name of the network that allows those connections)

I tested this by running docker-compose locally, and then opening the wiki and making an edit / checking that pages were there. (I used a mysql backup of the wiki to test this stuff)

For some reason, GitHub is displaying my image rotated. The actual image has the proper orientation. Strange.

Anyway, changed the link to one on Imgur.

Why not used depends_on ? Also, we seem to not have health status for the container to check if they are up. We should add them maybe?

@sam17 Why do you want to use depends_on? 🤔 These are simply connected over the network. If the other container is down, the app won't work. But there is no need to start them in a particular sequence.

(I don't know about the health status feature, can you please open an issue describing how it might help us? 🙌 )

@icyflame @sam17 Please update.
