Learning Docker by Building a Container Engine from Scratch

# Learning Docker by Building a Container Engine from Scratch If you've used Docker for any length of time, you've probably internalized the vocabulary. Images. Containers. Dockerfiles. `docker run -d --name my-app nginx`. It works. You ship code. Everyone's happy. But here's a question: what actu…
