Last year we open sourced a Containerization framework and container CLI tooling to enable developers to create and run Linux container images directly on their Mac in a way that focuses on security and privacy. In this talk, we'll dive into the Containerization framework, describing its foundational role in creating the container CLI which enables users to build, run and deploy Linux containers on Mac. We’ll walk through the architecture, highlight key APIs and discuss why we wrote it in Swift. We’ll then discuss some of our future roadmap for feature development and integration opportunities and challenges in the existing open source ecosystem.
