I'll assume that by IP you actually mean a socket, e.g. your nginx1 container will listen to the IP address #1 (let's say 1.2.3.1) on port 8080 and your nginx2 container will listen to your IP address #2 (let's say 1.2.3.2) on port 8081.

The option --publish will fulfill your need. It is used with docker run as so:

docker run -d --publish=1.2.3.1:8080:80 -name nginx1 nginx

This command will start the image nginx as a container named nginx1 in background mode and the socket 1.2.3.1:8080 will be bound to the port 80 of the container. As for nginx2: docker run -d --publish=1.2.3.2:8081:80 -name nginx2 nginx.

To combine it with docker compose you'll just need to add these options in the .yml file and you're done!
