Welcome to your new Rust function project! The boilerplate axum web server is in src/main.rs. It's configured to invoke the index function in src/handler.rs in response to both GET and POST requests. You should put your desired behavior inside that index function.

The app will expose three endpoints:

• / Triggers the index function, for either GET or POST methods
• /health/readiness The endpoint for a readiness health check
• /health/liveness The endpoint for a liveness health check

You may use any of the available axum features to fulfill the requests at those endpoints.

This is a fully self-contained application, so you can develop it as you would any other Rust application, e.g.

cargo build
cargo test
cargo run

Once running, the function is available at http://localhost:8080 and the health checks are at http://localhost:8080/health/readiness and http://localhost:8080/health/liveness. To POST data to the function, a utility such as curl may be used:

curl -d '{"hello": "world"}' \
  -H'content-type: application/json' \
  http://localhost:8080

Use func to containerize your application, publish it to a registry and deploy it as a Knative Service in your Kubernetes cluster:

func deploy --registry=docker.io/<YOUR_ACCOUNT>

You can omit the --registry option by setting the FUNC_REGISTRY environment variable. And if you forget, you'll be prompted.

The output from a successful deploy should show the URL for the service, which you can also get via func info, e.g.

curl $(func info -o url)

Have fun!
