Sample project configuration of a Restate service using the Go SDK.

5+
You can run locally with `go run .` and register to Restate with
6+
`restate dep add http://localhost:9080`. Then you can invoke with `curl localhost:8080/Greeter/Greet --json '"hello"'`.
7+

You can build a docker image using [ko](https://github.com/ko-build/ko):

`ko build --platform=all`
