Summary
Containerization is an open‑source Swift package from Apple that enables running Linux containers on macOS by leveraging the Virtualization.framework and lightweight VMs. It includes APIs for managing OCI images, registries, ext4 filesystems, networking, and even Rosetta 2 translation for x86_64 processes.
Highlights
- Runs each Linux container inside its own optimized lightweight virtual machine using Apple's Virtualization.framework.
- Provides high‑level Swift APIs for OCI image handling, remote registries, filesystem creation, and container lifecycle management.
- Includes the vminitd init system with a gRPC API over vsock to configure runtime environments and launch processes.
- Supports Apple Silicon Macs running macOS 15+; requires Xcode 26 Beta or later to build.
- Comes with the cctl command‑line tool for experimenting with container operations such as image manipulation, registry login, and root‑fs creation.
