ipieces is a Go package used to create Geocaching puzzles such as GCB1ZXB.
Available at https://pkg.go.dev/github.com/bitlux/caches/ipieces.
I deploy on Google Cloud Run. https://cloud.google.com/run/docs/quickstarts/build-and-deploy/deploy-go-service is a good reference on how to us Google Cloud Run.
Create a directory for your project and put your code in a file named main.go. Run
go mod init <module name> to create a module (because your main.go imports packages outside the
standard library, Google Cloud Run requires it to be in its own module).
To deploy, cd to the directory with your main.go file and run:
gcloud run deploy --source . <service> [--allow-unauthenticated]
where <service> is any name you want.
To set the IP address of the request to foo, use:
curl -H "<backdoor>: foo" localhost:8080/text
where <backdoor> is the Puzzle.Backdoor string you set.
I welcome issues and pull requests on GitHub and messages and email on geocaching.com.
