We must summon the strength, the will, and the faith to move forward - to be bold - to invest in our future. This tutorial aims to be the one-stop shop for getting your hands dirty with Docker.

In terms of Docker, a bridge network uses a software bridge which allows containers connected to the same bridge network to communicate, while providing isolation from containers which are not connected to that bridge network. And it's a way to hide your provision code. We say images are immutable, but when being run as a container it stores any changes to the mutable top layer as you said.
