Fixes#212
This PR:
- adds a `package func resolved()` on `ClientImage` that makes use of
the new `com.apple.containerization.index.indirect` annotation to
identify and resolve wrapper indices created by Containerization;
- replace the digest displayed in `container image list` with the one of
the resolved manifest;
- use the resolved manifest for `container image inspect` if the index
is a wrapper.
We're working on making a pure swift container image build system that
leverages containerization. This PR represents our initial design and
initial work towards this goal.
The native builder is still in active development and most of the
implementation has not been started or completed. We will be opening a
series of issues that represent various (but not necessarily all) pieces
of work that need to be done here.
There are docs included in this PR that describe the overall design of
each component and outline some of our goals. The easiest way to view
the docs by themselves (since this is a massive PR) is to look at the
docs commit in the `Commits` tab.
We'd love any feedback!

This matches other container commands that rely on user arguments at the
end, such as `container run`. Closes#395.

0.5.0 introduces a new way to configure the containers and execs. This
is now done all upfront at constructor time in a callback style. I'm
very happy with the config improvements, but because IO can only be
setup at constructor time this makes it so that we need to supply IO at
creation time of the VM or exec, which isn't the end of the world. All
that really changes is `boostrap()` and `createProcess()` now take in IO
instead of slightly later in `process.start()`
readabilityHandler is a bit crummy if it's a regular file. This just
writes our own loop and exits and shuts down the write end of the pipe
if we get to the end of the file.
Looks like we've been ignoring the "cause" field for
ContainerizationError when sent over xpc. Add the cause to the
`ContainerXPCError` message field instead of a new `cause` field since
`Error` is not encodable. The goal here is just to preserve information.

I want to access the different variants of an image in my app, which
information is only available in the ImageDetail. Although the function
ClientImage.details() -> ImageDetail and its return type are already
public, its properties aren’t, which prevents access to this
information.
Changed `SandboxSnapshot` initializer from `package init()` to `public
init()` to enable external package consumers to create and use
`SandboxSnapshot` instances in their custom Sandbox plugins.
The `SandboxSnapshot` is used for `container list` functionality
* Closes#148.
* Storing the default nameserver in the bundle config means that DNS
won't work if the container stops and then restarts later when the
subnet address has changed.
Define a `UnpackStrategy` function type in the `SnapshotStore` to give
more control over how an image is unpacked.
Previously, we were creating a 512 GB sparse block file for the initial
file system of a container, which is overkill.
With this change, the vminit image is unpacked to a smaller block file,
while container images are unpacked to the 512 GB block
Follows the same pattern as
https://github.com/apple/container/blob/main/Sources/Helpers/RuntimeLinux/RuntimeLinuxHelper.swift#L71

See discussion below for example. For multiple network interfaces in a
single container we'll want to integrate against a containerization that
includes apple/containerization#156.
The change bumps the containerization dependency to 0.2.0 and addresses
the breaking API changes.
```console
% container network
OVERVIEW: Manage container networks
USAGE: container network <subcommand>
OPTIONS:
--version Show the version.
-h, --help Show help information.
SUBCOMMANDS:
create Create a new network
delete, rm Delete one or more networks
list, ls List networks
inspect Display information about one or more networks
See 'container help network <subcommand>' for detailed help.
```
Closes https://github.com/apple/container/issues/80
Adds the following help message if you try to run `container` against a
host that hasn't started the container system:
```
❯ /usr/local/bin/container list
Error: internalError: "failed to list containers" (cause: "interrupted: "Connection invalid: ensure container system has been started with `container system start`"")
❯ /usr/local/bin/container run -it --rm docker.io/alpine
Error: interrupted: "Connection invalid: ensure container system has been started with `container system start`"
```
This PR resolves a race condition when removing a container immediately
after stopping it, caused by the `stop` command returning before the
container fully transitions to the stopped state (#130).
**Changes:**
- Enhanced `TestCLIRmRace.swift` with robust test logic and helper
methods (`containerExists`, `safeRemove`).
- Improved error handling to distinguish race conditions from successful
removals.
- Added exponential backoff retry logic for cleanup operations.
- Updated `CLITest.swift` with missing `doRemove` method.
- Fixed `BuilderStart.swift` to handle `.stopping` case.
- Improved error messages with container ID for better debugging.
**Testing:**
- ✅ All tests pass (`make test`, `make integration`).
- ✅ Verified on macOS 26.
- ✅ Race condition test validates success and failure scenarios.
- ✅ Code formatted (`make fmt`).
Hopefully, this will pass the integration tests on GitHub.

Implements a way for the CLI to wait until the IO streams from the
SandboxService have been drained before closing them.
Follows the same pattern as
https://github.com/apple/containerization/pull/110
This change also performs some cleanup in the
`SandboxService.startProcess` method - splitting the code paths to
handle the init process and an exec'd process into two different private
methods to make easier reading

This change consolidates the UserDefaults service name
`com.apple.container.defaults` to a single constant under the extension
file and also renamed the extension file.
