Motivation

You often have several docker containers and applications which work together in the locel development environment. You need the following communications:

• docker container to localhost
• localhost to docker container
• docker container to docker container

You have a way to connect localhost-to-docker using -p (port-mapping) docker option. For instance, you can start PostgreSQL container using -p 0.0.0.0:5432:5432 and then connect like to normal PostgreSQL
