## The Hook

Docker made "works on my machine" a solvable problem.

## What's Good

Containers are the universal deployment unit. Dockerfile syntax is approachable. Docker Compose handles multi-container development. The ecosystem is massive.

## The Catch

Resource overhead compared to native. Security requires attention. Desktop licensing changes affected teams. Image size management is ongoing work.

## Verdict

Containers are table stakes; Docker is how most start.
