I have a Quarkus based application with a REST endpoints deployed in a Docker container. An application creates Open API document and send it back to the client. There is section Info about the server urls. I can set only a internal url as host name. How to get the external/public Url of this application?

Flow looks like here: Client -> Docker -> Container -> App -> (Resolve public URL) -> Add URL to OpenApi.Info -> Send back to the client.
