How to send a request to another microservice in a docker container?

Question

Docker

Good afternoon, there is a docker-compose file with services service1, service2, postgresdb, nginx-proxy. All http requests go to nginx-proxy, there is no web server on service1, service2, only php-fpm. Everything works great from the host machine, but now how to make an http request from service1 to service2 through nginx-proxy? There is an option to write something like service1 to the hosts file.
service2 nginx-proxy
But what if there are a lot of services or no rights for editing. Is there a way out?
