The deployment issues were caused by sequelize running out-of-order.
I fixed this by placing sequelize.sync() in correct locations.
I've also updated news-server with these changes.
I've also removed mariadb stuff from the game server's Dockerfile.
Resolved#1
MariaDB's root password needs to be hidden from the game server's container,
so I've changed the startup logic. MariaDB supposedly runs certain files that
are found in a specific directory, so I'm using volumes to place startup.sql
there.
This needs testing on a mock deployment server.
