fortune is an intentionally boring, production-ready Go service that serves random fortune cookies over HTTP.
It's built with minimal dependencies and reuses internals from pkgsite (the Go package index), adapted to work with MySQL. The service runs on a lean, GCP-native stack with full observability—logging, metrics, tracing, and profiling included. The goal is to show what a Go backend can look like when it's easy to understand, straightforward to deploy, and ready for real use.
API
The API has two endpoints. GET / returns a random fortune from the database. POST / accepts a plain text body with fortunes separated by %, as per the original format of the Unix fortune command.
Third-party code
I adapted the internal/database package to support MySQL. The other packages (memory, middleware, wraperr) are mostly unchanged apart from some cleanup. There's also a small CLI tool under devtools/cmd/db to help with database tasks, and a trimmed-down all.bash script for linting and tests.
