A pre-configured development container providing all tools, libraries, and runtime dependencies required to build software—works identically on Windows, macOS, and Linux.
What Is DevContainer Toolbox?#
DevContainer Toolbox establishes a single, reproducible development environment that works identically on Windows, macOS, and Linux—eliminating environment drift and the classic “it works on my machine” problem.
By using the Dev Container standard, the entire development environment is defined as code and version-controlled alongside the application source. When a developer checks out a repository, they get not only the code, but also the exact tools, runtimes, CLI utilities, and configurations required to build, run, debug, and test it—ready to use in minutes.
Fast and Predictable Onboarding#
Onboarding new developers becomes trivial. There is no need for lengthy setup guides, local tool installation, or troubleshooting OS-specific issues. Opening the project in a supported IDE automatically builds and launches the devcontainer with everything installed and configured.
This enables:
- New developers to be productive on day one
- External consultants to work in a controlled, compliant environment
- Teams to scale without increasing setup and support overhead
A Toolbox, Not a Single-Purpose Container#
DevContainer Toolbox is designed as a shared foundation for many types of development work. It includes a rich base environment and a modular architecture for extending functionality as needed.
The .devcontainer directory is structured to support this:
| Directory | Purpose |
|---|---|
manage/ | Commands and orchestration logic for setup, extension, and maintenance |
additions/ | Scripts that install and configure tools for specific languages and use cases |
This approach allows teams to enable support for multiple programming languages and technology stacks from a single, standardized container image.
Multi-Language Support#
The toolbox includes commands and templates for:
| Languages | Frameworks |
|---|---|
| C# / .NET | Next.js, React |
| Python | Express, Spring Boot |
| Node.js / TypeScript | Web APIs |
| Go, Java, PHP | Backend services |
IDE and Platform Support#
Works consistently across Windows, macOS, and Linux with:
- Visual Studio Code
- JetBrains Rider
- Visual Studio
The container abstracts away host OS differences, ensuring that builds, scripts, and tooling behave the same for every developer.
Security and Stability#
Because all tooling runs inside the container:
- The local machine remains clean and unaffected
- Developers can safely experiment without breaking their host system
- Tool versions and dependencies are pinned and auditable
- Security teams gain better control and predictability
The base image is built on Debian 12 (Bookworm) and includes essential CLI tools such as Azure CLI, Python, Node.js, and common utilities required for modern cloud-native development.
Key Benefits#
- Consistent environments across all developers and platforms
- Ultra-fast onboarding with no manual setup
- Environment-as-code checked in alongside application source
- Modular architecture for diverse development needs
- Reduced support overhead and troubleshooting
- Improved collaboration through identical tooling and workflows
