There are multiple ways to do this and the simplest answer is to use Docker-Compose. You can use Docker-compose to allow multiple services to run a server.

If you are not using Docker-Compose and running individual container than expose both services port with host and then use those services on such on links like:

docker run -p 3306:3306 mysql

docker run -p 8088:80 nginx

Now you can communicate as:

http://hostip:3306 http://hostip:8088 etc. Now you can communicate with container using hostIP.
