To run docker inside docker, all you have to do it just run docker with the default Unix socket docker.sock as a volume. Just a word of caution: If your container gets access to docker.sock, it means it has more privileges over your docker daemon. So when used in real projects, understand the security risks, and use it.Why should you use Docker?
Docker is a basic tool, like git or java, that you should start incorporating into your daily development and ops practices. Use Docker as version control system for your entire app's operating system. Use Docker when you want to distribute/collaborate on your app's operating system with a team.
