Test create func

func create -l node helloworld
cd helloworld
func build
> localhost:5000/helloworld

$ func build
A registry for function images is required. For example, 'docker.io/tigerteam'.
? Registry for function images: localhost:5000/helloworld
Note: building a function the first time will take longer than subsequent builds
   🙌 Function built: localhost:5000/helloworld/helloworld:latest
$ func deploy
function up-to-date. Force rebuild with --build
   ✅ Function deployed in namespace "default" and exposed at URL:
   http://helloworld.default.127.0.0.1.sslip.io
