Dev container features for modular installation of tools like Docker-in-Docker, Kubernetes, Terraform, and language runtimes. Docker Compose support for multi-container environments with databases and message queues. Attach VS Code to already running containers for debugging containerized applications. Wizard for creating new devcontainer.json from templates. Automatic port forwarding from container to host with labels and visibility configuration.
