Answer 1

Docker is written in go language. The two fundamental principles you need to understand are the cgroup and namespacing capabilities of the Linux kernel.

Have a look at the docker's github source code repository and contributing to docker guide. Also, you can check this book, it explains how to extend docker.

For the source code, you can start from docker.go file.

Hope this will help.
