Dev Containers provide a portable and consistent development environment for engineering teams by defining languages, tools, services, and configurations in a Dockerfile. This eliminates the "works on my machine" problem and allows developers to spin up sandboxed environments that contain everything they need to be productive. However, creating well-configured Dev Containers requires expertise in several domains, including Docker, Linux, infrastructure automation, VS Code extensions, and more. To simplify the process of authoring robust and reusable configurations, helper libraries are needed to abstract away common implementation details such as multi-OS support, multi-architecture, idempotence guarantees, permission and path management, package installation and management, Bash scripting best practices enforcement, VS Code/IDE integration, and documentation alignment. With these helper libraries, developers could create Dev Containers by composing high-level constructs representing the needed components, handling complexity under the hood.
