Using Hummingbird with Docker

[sanvean]

Just a little tip for anyone looking deploy something with Hummingbird using Docker.

Use "0.0.0.0" as your hostname and not "127.0.0.1" or localhost as well as adding port forwarding.

e.g.

let app = HBApplication(configuration: .init(address: .hostname("0.0.0.0", port: 8080)))

Docker Container
-p 8080:8080

Docker Compose
ports:
- '8080:8080'

Otherwise you'll get a connection refused error when trying to reach your HB routes even though Hummingbird looks like it's running nicely in your container.

p.s. Thanks for the great library @adam-fowler, exactly what we were looking for to add on some simple web based functionality to an existing Swift server component.

@sanvean Yes this is a good point.

I have also released a template repository which includes a basic template for a Hummingbird project. This includes a Dockerfile that defaults to using 0.0.0.0
