You can’t create something out of nothing.
Docker Deep Dive
When I want to learn how Docker works behind the scenes, I searched a lot online, but the output is very limited. And ‘Docker Deep Dive’ is the only one I can find! This book covers many topics related to Docker. It doesn’t show the source code level details, but it serves as a good starting point for the exploration of the container technology world. The explanation of VXLAN in the Docker networking part is the most impressive chapter for me.
