## Quick Example for a Go Function (3 minutes) This example will show you how to test and deploy Go (Golang) code to IronFunctions. ### 1. Prepare the `functions.yaml` file: At functions.yaml you will find: ```yml app: goapp route: /hello image: USERNAME/hello:0.0.1 build: - docker run --rm -v "$PWD":/go/src/ -w /go/src/ -e "GOPATH=/go/src/vendor:/go" iron/go:dev go build -o hello ``` The important step here is to ensure you replace `USERNAME` with your Docker Hub account name. Some points of note: the application name is `goapp` and the route for incoming requests is `/hello`. These informations are relevant for the moment you try to test this function. ### 2. Build: ```sh fnctl publish ``` `-v` is optional, but it allows you to see how this function is being built. ### 3. Queue jobs for your function Now you can start jobs on your function. Let's quickly queue up a job to try it out. ```sh cat hello.payload.json | fnctl run goapp /hello ``` Here's a curl example to show how easy it is to do in any language: ```sh curl -H "Content-Type: application/json" -X POST -d @hello.payload.json http://localhost:8080/r/goapp/hello ```
