Push-button deployments with Arduino

Love the physical buttons. Reminds me of the starting scene of War Games… https://youtu.be/rLMCjuge6oE

SmugMug Sorcery

TL;DR: Thanks to an Arduino, an Arduino ethernet shield, some Arduino code, buttons from eBay, LEDs from Fry’s, and SmugMug’s deployment web app, we’ve created a push-button deployment process that looks like this:

When I first started working at SmugMug, we deployed infrequently by manually merging branches, tagging, double-checking, then running a bunch of commands (some via sudo and some not). It was an eleven step process that not all developers had access to. Developers were usually uneasy about pushing due to the complexity involved.

Eventually the process was consolidated into a shell script, which still had to be run via sudo on a designated server. More recently, the shell script was wrapped in a web app that made things much easier.

While the web app is pretty awesome and easy to use, I thought using a real physical button to deploy code would be even better:
