- Adds a a `--log-root` option to `swift system start`, propagating the
value as `CONTAINER_LOG_ROOT` to services for logging to files instead
of the OS log facility. This is not a "production" capability as it
neither merges nor rotates logs.
- Currently we don't collect logs on CI builds, and we don't have
permission to run the `log` command there. The PR adds `--log-root` to
the CI test phase, archives the results, and uploads the archive as an
artifact.
- Use FilePath from swift-system for the log root. Foundation URL is a
bit of a footgun for filesystem paths, so unless we identify a
showstopper, we should incrementally transition to this type everywhere
except where we really need network URLs.
- Output the hostname of the CI runner at the start of the test phase so
we can identify runner-specific issues where they exist.
- Fix formatting for log messages with multiple metadata items, and fix
unstructured messages on instances that weren't found using `grep -r
'log\.' Sources`.
- Adds command reference documentation for `--log-root`.
## Type of Change
- [X] Dependency bump
## Motivation and Context
This change is needed to pick up the fix to allow
containerization to compile successfully in linux
relevant PR: https://github.com/apple/containerization/pull/544
## Testing
- [X] Tested locally
- Closes#1206.
- Closes#1185.
- Closes#507.
- Addresses existing log messages for #642.
- Nondeterministic CI errors are resulting from very slow launch times
for the first runtime helper, which causes ContainersService to be
locked for longer than our 20 sec timeout. Bumping the timeout to 60
seconds addresses this case for now.
- Since many log messages needed to be changed to troubleshoot the
issue, updated all log messages to use structured logging, and
implemented consistent entry/exit logging for all service operations.
- Added logging for ContainerService lock acquisition to help with
finding root cause for the slow service startup.
- Plumbed the `--debug` flag on both `container system start` and
`container system logs` so that the flag is actually useful.
- Updated the `install-init.sh` script so that can install in a custom
app root directory.

Closes#1202
Today it's possible to pass a memory amount that very easily will cause
the container's VM to not be able to boot. We should protect against
this to avoid weird hangs/error messages. I could be convinced that a
limit should be in Containerization as well, but I think having one in
the daemon is a decent idea regardless.

## Motivation and Context
We want to be able to support using multiple network plugins during
`container`'s lifetime. This additionally means needing to pick an
interface strategy to interpret a network attachment based on what
network plugin was used to create that attachment. This PR will
potentially replace https://github.com/apple/container/pull/1081.

creation cli

## Motivation and Context
- CI build is failing because runners don't have an /etc/resolver
directory, causing the directory monitor to fail. This occurs while the
install-kernel make target is running, so it appears that kernel
download is failing when it's just that the API server is dying. Created
#1207 for the issue.
- Fixing the initial scan for the directory just moves the problem to
the filesystem watch loop, likely because we're not testing the result
of `open()` for errors.
- Right now the priority is getting CI running and PRs merged, so just
commenting out the realhost DNS server setup.
- Also seeing that under some conditions it can take quite a while for
launchd to start the helper for the default network (8 seconds or more).
With the 10 second health check timeout after API server registration,
this means that some CI runs can exhibit this failure mode. Added a
`--timeout` option to SystemStart and set a 60 second timeout for
install-kernel and integration Makefile targets.
- Fixed a bug where `--debug` was being placed in the wrong location in
the api server startup args.
- Disabled all network CLI tests due to container bootstrap errors when
trying to run the container immediately after creating the network. The
slow network helper launch could be the reason behind the failures that
drove us to serialize these tests. Filed #1206 for this issue.

This is not intended to be used to support `--filter` or similar on the
CLIs list yet, it's solely to clean up our rather awkward use of
`ContainerClient.list()` today in the CLI. The list RPC simply returns
all of the containers we have created. Because of this, for a LOT of our
commands we filter to what we need client side, which feels like a
waste.. This change introduces a filter struct that we can provide an
array of container IDs, labels, and the status of the containers to
filter the `list()` output from.
This additionally, because it was killing (pun not intended) me and I
was already having to change this area for the `list()` additions,
changes container kill slightly to return an error if you try and kill a
container that doesn't exist.
`make test` occasionally fails with:
```
✘ Test testHostDNSReinitialize() recorded an issue at HostDNSResolverTest.swift:132:45: Expectation failed: (error →
Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory") as? (ContainerizationError → NSError)
✘ Suite HostDNSResolverTest failed after 0.119 seconds with 1 issue.
```
- Implemented the TODO at
ContainerAPIService/Client/Utility.swift:358 — warn the
user when a named volume is auto-created.
- This only triggers for named volumes (not anonymous
ones), matching Docker's behavior of informing users
about implicit resource creation.

- Closes#1150.
- The problem seems to be that the selinux label attribute enforcement
doesn't play well with overlayfs.
- Solution is to set the `lsm` boot line argument. The new value
corresponds to what one would see in a Lima VM with Colima. The Kata
kernel we use doesn't provide any of those modules, so now if you run
`dmesg | grep -i lsm` in a container you will just see: `LSM:
initializing lsm=capability`
Send the hash of entire tar file in the first BuildTransfer packet to
prevent container-builder-shim from using stale cached contents.
This PR resolves#1143.
This PR relies on apple/container-builder-shim#64.
## Type of Change
- [X] Bug fix
- [ ] New feature
- [ ] Breaking change
- [ ] Documentation update
## Motivation and Context
Current container-builder-shim uses only first few bytes of tar file as
checksum, which leads to the usage of stale cached contents if the
change of build context is not included in the first bytes of tar file.

Instead of logging errors, and then additionally throwing an error
stating what containers couldn't be stopped/killed/deleted, let's just
concatenate the errors and throw the single error.

## Motivation and Context
The PR labeler workflow has been failing for a while but it's difficult
to know how to fix it since the PR labeler workflow is run from main
(aka NOT the current PR branch) for security reasons. Example at
https://github.com/apple/container/actions/runs/21690229300/workflow
ClientContainer was honestly extremely awkward. It could only be created
by passing either a ContainerConfiguration, or a Snapshot that had to be
obtained from calling a static method on the type itself. The type also
did not store a connection, so every single method got a new xpc
connection to the APIServer. This change aims to rework this type to be
just a generic client, that is *not* a client for one specific
container, but for any.
- Rename to ContainerClient
- Have list() return [ContainerSnapshot]
- Create a connection in the constructor
- Change all the callsites to use the new API
- Small, somewhat related, change to logs API in the APIServer. Now that
we don't need to call get() to grab a client anymore which was typically
what did "does this container exist" logic and gave a nice error
message, I added a small check in the APIServer to see if the container
exists and return mostly the same error message.
- Closes#1122.
- Adds placeholder ManagedResource and unit tests. Nothing is using
these yet.
- Adds system-defined resource labels for owning plugin and resource
role. The system discriminates the builtin network using role "builtin".
- Adds builtin role when creating builtin network at startup, and
ensures that a preexisting network with ID "default" gets updated with
the role label.
- Replace all network ID checks for "default" with the builtin role
check.
- Adds "builder" role to builder VM.

## Summary
The `reload()` method in `PacketFilter.swift` references
`/sbin/reloadProcess` (the local variable name) instead of
`/sbin/pfctl`. This causes all DNS create and delete operations to fail:
```
Error: internalError: "pfctl reload exec failed: "Error Domain=NSCocoaErrorDomain Code=4 "The file "reloadProcess" doesn't exist.""
```
## Fix
One-line change: `/sbin/reloadProcess` → `/sbin/pfctl`
## Testing
Verified on macOS 26 (Tahoe) with Apple Silicon:
- `sudo container system dns create test.sdc.internal --localhost
203.0.113.1` succeeds without error
- Container can resolve and reach host services through the DNS redirect
- `DirectoryWatcher` opens file descriptors for monitoring
directories but never closes them, causing a file descriptor
leak.
- Adds `setCancelHandler` to properly close file descriptors
when the `DispatchSource` is cancelled.

- Closes#1113.
- This is the newest we can do until we address #767.
- Slight change to PacketFilter error handling so unit tests work more
reliably.
- Try making CLINetworkTests serialized to see if parallel execution is
causing flakes.
The old mtu default in containerization was 1280 to account for some
alpine/musl images that have issues with
1500. This changed in the last couple tags to be modifiable, but the new
default is the standard 1500. Ideally we eventually allow supplying the
mtu to be used when you create a network (or possibly a container
creation setting), but for now just default in here back to what CZ used
to use.

- Refer to #862
- Updated `SIZE` field to `FULL SIZE`, as it seemed more appropriate so
it does not get mixed up with the `descriptor size` field
- Closes#860
- Fixed#892.
- By contrast with `rm`, `prune` should display
