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:

Access from host network
kubectl port-forward --namespace kourier-system service/kourier 8080:80 --address 0.0.0.0
