Today I completed the fourth and last module of the "Docker Networking" course. The last bit was kind of overwhelming since I had never dealt with docker services before, and they were foundational to most of the explanation.
Anyway, I'm gonna make up for it with the "Docker Deep Dive" course from the same author.
I watched 42m of content, for a total of 2h 1m.

Completed modules 1, 2, and 3 of Nigel Poulton's "Docker Networking" course. In total, I watched 1h 19m of content.

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!
