    # This allows `web` to access api.dev.readup.org, leave the containers
    # to the host at localhost, then enter the proxy container via the mapped localhost:443,
    # and then get directed to the `api` container via the proxy.
    #
    # TODO: this seems inefficient, it's maybe possible to skip this indirection via the host:
    # - Somehow direct api.dev.readup.org within `web` to readup-proxy
    #   (it's not possible with extra_hosts. Maybe with a DNS server inside `web`?
    #    If that's more efficient.)
    # - Or, web's config files could not try to connect to https://api.dev.readup.org,
    #   but to http://readup-api:5001 instead, in case of the Docker dev env.
    #   However, then we lose the HTTPS at the proxy level.
