Pi Infrastructure

Checkins for a raspberry pi setup and k3s cluster I'm playing around with.

What's hosted?

recipe-maker

I got tired of having to pick what to eat for dinner each month, thus recipe-maker was born. recipe-maker selects and renders a month's worth of recipes, including related grocery list. Comes in two modes:

Server deployment:

Deployed on k3s using a Deployment + NodePort Service. This allows viewing this month + next month's meals from my phon, laptop, or tablet by hitting the same URL. Links are clickable for finding related recipes.

Email CronJob:

Deployed on k3s using a CronJob. Every Friday, finds next week's recipes and compiles a grocery list for all items, combining like items by quantity, and assigning each item to its respective aisle. This is then formatted and emailed to me and my partner.

Data:

Recipes are stored in a JSON file in a private repository shared with my partner. This repo has CI/CD setup to validate the contents, and push the JSON file's latest state to S3. This state is then pulled by the recipe-maker.

While we could just pull from the GitHub repo itself, CD in this way is far more fun!
