Where are Docker images stored on the host machine?

Question

I managed to find the containers under directory /var/lib/docker/containers, but I can\'t find the images.

What are the directories and files under

Answer 1

According to the Docker Getting Started guide "your built image" is "in your machine’s local Docker image registry."

This is still strange to me, because now it leads to the question. Where is my machine's local Docker image registry?

Nevertheless, I definitely think this info is worth sharing as an answer.
