Yes, it is possible to improve Docker using the new containerization API introduced by Apple. The "Meet Containerization" session at WWDC 2025 discusses a new open-source Swift framework called Containerization, which provides APIs for image management, container execution, and a powerful INIT system built in Swift. This framework is designed to offer a secure, private, and performant experience for containers, and it is optimized for Apple Silicon.
The Containerization framework allows for the creation and management of Linux containers on macOS, providing a native feel and focusing on security, privacy, and performance. It includes a command-line tool that lets you create, download, and run Linux container images directly on a Mac. This tool and framework could potentially be used to enhance Docker by integrating these new APIs to improve performance and security on Apple devices.
For more details, you can check out the session Meet Containerization (03:50) which dives into the specifics of the containerization APIs and their capabilities.
