- Part of #515. - Add titles to option groups for container subcommands. - Order option groups and container subcommand options alphabetically. - Use `container-id` and `container-ids` consistently as argument names. - Shorten long valueNames to avoid option column overflow in help output where possible. - Replace customShort and customLong with short, long, and shortAndLong where possible. - Always place global options and arguments after alphabetized command-specific options. - Rename RunCommand to ContainerRun and relocate it. - Rename Executable to ContainerCLI. ## Type of Change - [ ] Bug fix - [ ] New feature - [x] Breaking change (if you're depending on `RunCommand`, renamed). - [ ] Documentation update ## Motivation and Context See #385. ## Testing - [ ] Tested locally - [ ] Added/updated tests - [ ] Added/updated docs
container
container is a tool that you can use to create and run Linux containers as lightweight virtual machines on your Mac. It's written in Swift, and optimized for Apple silicon.
The tool consumes and produces OCI-compatible container images, so you can pull and run images from any standard container registry. You can push images that you build to those registries as well, and run the images in any other OCI-compatible application.
container uses the Containerization Swift package for low level container, image, and process management.
Get started
Requirements
You need a Mac with Apple silicon to run container. To build it, see the BUILDING document.
container is supported on macOS 26, since it takes advantage of new features and enhancements to virtualization and networking in this release. We do not support older versions of macOS and the container maintainers typically will not address issues that cannot be reproduced on the latest macOS 26 beta.
Install or upgrade
If you're upgrading, first stop and uninstall your existing container (the -k flag keeps your user data, while -d removes it):
container system stop
uninstall-container.sh -k
Download the latest signed installer package for container from the GitHub release page.
To install the tool, double-click the package file and follow the instructions. Enter your administrator password when prompted, to give the installer permission to place the installed files under /usr/local.
Start the system service with:
container system start
Uninstall
Use the uninstall-container.sh script to remove container from your system. To remove your user data along with the tool, run:
uninstall-container.sh -d
To retain your user data so that it is available should you reinstall later, run:
uninstall-container.sh -k

Project Status
The container project is currently under active development. Its stability, both for consuming the project as a Swift package and the container tool, is only guaranteed within patch versions, such as between 0.1.1 and 0.1.2. Minor version number releases may include breaking changes until we achieve a 1.0.0 release.
