Game On! Explore microservices with a text-based adventure

Microservices: the buzz is everywhere. Given the breadth of technologies related to the term, it can be difficult to get a full picture of what a Microservices architecture should look like, or to understand why it is said that microservices architectures both remove and introduce complexity at the same time. [Game On!](https://game-on.org) is a throwback text-based adventure built to help you explore microservices concepts.

Swagger-first API design

I’ve been working for the past few months on building Game On! a microservices-based application that is intended to show both what a microservices architecture looks like, and to make it easy for people to play with such a system without having to start from the ground up themselves.

We started with a best-guess set of services, and over time, it became pretty apparent that our first pass at a map building service (the Concierge) was both misleading in purpose and insufficient in function. It did serve its purpose, filling in for service discovery in a way, but we were growing beyond what the service could do.

Shell prompt crazy for Git Submodules

I’ve run a somewhat odd little script to generate my command prompt for years now, sets some colors, adds some indicators of what kind of shell I’m in (sudo or tmux/screen or ssh or.. ).

Given I now have to work with git and submodules, I’ve revised that to include information provided about git generated by this script: https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh

The difference is worth it, in understanding at a glance what is going on without typing git status or variant every two seconds. ;)

I’ve also been using some very useful aliases to make working with submodules sane, as documented here: Game On! Advanced Adventures / Git Submodules

Trying to tell the human story...

Writing is always hard. Writing technical stuff is hard. Writing technical stuff that doesn’t sound like it is a regurgitated text book… sigh

I’ve been leading a team working on or with Microservices at IBM (lots of people everywhere are doing things with microservices, this should come as no surprise). We’ve been specifically looking at how to modernize an existing Java EE application. There are articles about this, but they are all formal, and (to me) preachy.

We’re doing the experiment live, so to speak. Taking the crufty Plants By WebSphere application and pulling it apart bit by bit. Our aim is to make sure you have a functional application at all times, and to frankly just share our thoughts as we try it. Let us know what you think.
