How to make a docker container send an HTTP request to another container running in same network
I have two apps -- app1 is running on localhost:8081. app2 is running on localhost:8082. App1 is makes an HTTP GET request to app2, and app2 returns a simple json response. This all works just fine when running both apps locally on my mac, since I'm having app1 send a GET request to "http://localhost:8082".
But when containerizing both of these apps (and running them on the same network), what url should app1 be sending the GET command to? It's hard-coded as "http://localhost:8082", and the 8082 port is exposed in the app2 container, but communication isn't happening.

If you have two containers running in the same network via docker-compose, you can perform the request to their specified name in the docker-compose.yml file. If not using docker-compose, you can name the containers using the --name flag with the docker run command.
