A single misplaced COPY instruction in a Dockerfile can lead to a 2GB image and a 10-minute build time. Grider’s repetition drills the layer caching system into the student's muscle memory.

But what is it about Grider’s approach to Docker that resonates so deeply with a generation of coders tired of "It works on my machine" syndrome? stephen grider docker

In the first hour of his course, Grider doesn't show a single docker run command. Instead, he manually walks the student through the nightmare of dependency hell. He installs Node.js, Redis, Postgres, and a worker process directly on a local machine, deliberately breaking the environment to demonstrate how version conflicts and operating system differences derail development. He forces the student to feel the friction. Grider’s repetition drills the layer caching system into

Instead, he invests significant time deconstructing why containerization exists. Instead, he manually walks the student through the
