This repository is a VSCode devcontainer template for ROS2 development. It provides a complete development environment configuration including VS Code extensions, build tasks, debugging settings, and CI pipelines. The core functionality is orchestrated through shell scripts (setup.sh, build.sh, test.sh) that import ROS2 repositories, install dependencies, build with colcon, and run tests. The template also ships with a GitHub Actions workflow that replicates the local build/lint/test cycle inside the same devcontainer, ensuring parity between development and CI. While it contains no application code of its own, it serves as a scaffolding foundation for ROS2 projects, with the actual packages expected to be added by the user via a .repos file or directly in the src/ directory. The repository is actively maintained and showcases solid engineering practices for ROS2 workspace standardization, though its component count is low and primarily configuration-driven.
