The idea is not to pass the url, but the hostname of the other container you want to call.
See Networking in Compose

By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.

This is what replace the deprecated --link option.

And if your containers are not running on a single Docker server node, Docker Swarm Mode would enable that discoverability across multiple nodes.
