If you want to forward multiple services to the host, I have this module https://daggerverse.dev/mod/github.com/kpenfound/dagger-modules/proxy@33bc3eef07555d9fd4c22b02ff5c008a71a649e7 which lets you do that by exposing multiple ports on one service to any number of backend services. Here it is in action https://github.com/kpenfound/greetings-api/blob/main/ci/main.go#L47-L50
