DOCKER EXPLAINED: FINALLY UNDERSTAND CONTAINERS WITHOUT LOSING YOUR MIND

Summary from the TLDR InfoSec newsletter

This guide breaks down Docker in plain terms: containers package code with dependencies to avoid the “works on my machine” problem. It covers key concepts like `Dockerfile` “recipes,” `docker build` commands for creating layered images, registries for storing images, and `docker run` for execution. Containers offer faster, more consistent, isolated, and efficient environments for running applications across systems.
