Container is a Swift-based CLI tool that turns macOS 26 on Apple silicon into a lightweight Linux VM host. It handles OCI-compatible images—pull from any registry, run them locally, build your own and push back. Under the hood it uses Apple’s virtualization framework and the open-source Containerization Swift package to manage images, containers and networking without heavyweight dependencies. You install it by downloading the signed .pkg from GitHub Releases, double-clicking, then entering your admin password so files land under /usr/local. Once installed, start the background service with `container system start`. Upgrades or rollbacks happen through an included script: stop the service with `container system stop`, then run `/usr/local/bin/update-container.sh` for the latest release or specify a version for earlier builds. An uninstall script lives at `/usr/local/bin/uninstall-container.sh`; add `-k` to keep your data or `-d` to wipe it. The repo bundles docs for a guided tour—build, run and publish a simple web server image—plus a full command reference and API docs. You’ll find a BUILDING guide if you want to compile from source. The project sits at version 0.x, so expect possible breaking changes between minor releases; patch updates stay compatible. Contributions follow the main contributing guide on GitHub.
