A couple of days of relaxing have gone by.
Today I set aside the project "hexgrid" and switched to my old pal "geogame". The game currently has no game logic at all, since I'm focusing on the infrastructure first.
As the title suggests, today I laid down the foundation of the go server, which is going to sit between the database and the game client. Most of my effort went into understanding how to structure the project. From that, I then went on and channelized it into a docker image.
Let's see if next time I manage to write some go code and make it do something more thrilling!
