Dev Containers: Your Dev Environment as Code

A dev container packages your entire development environment—tools, libraries, and settings—into a single, portable container, treating your workspace as code. It's ideal for standardizing environments across a team, simplifying onboarding, and eliminating 'it works on my machine' issues by ensuring consistency between local dev and CI/CD pipelines. The biggest footgun is forgetting containers are ephemeral; without correctly configured volume mounts, your code changes will disappear when the container stops.
