Changes ssh socket path in container to
`/var/host-services/ssh-auth.sock` as the path `/run` (where the ssh
socket is mounted initially) is often mounted again by init systems, and
the ssh socket is hidden.

This PR fixes#357, passing `SSH_AUTH_SOCK` env variable from current
terminal to the `SandboxService` so that the container can mount the
correct ssh auth socket. For that, it introduces `env` parameters to
`bootstrap` RPC of both `ContainersService` and `SandboxService`. This
parameter is used only for passing `SSH_AUTH_SOCK` now, but can be
extended to pass more runtime env variables.
This PR is a follow up PR of #1214.

Closes#1352
Containerization has had support for a bit, it was just never brought
over here. It's exposed on the CLI via the classic `--cap-add` and
`--cap-drop` UX.
- Closes#1359.
- Create a ResourceLabels type and extract the label validation from
NetworkConfiguration into the new type.
- Create a base AppError type that is compatible with structured logging
and delegates message presentation to the error receiver.
- Define LabelError over AppError for label validation.
- Slightly reworks NetworkConfiguration entity migration code in
NetworksService.
## Motivation and Context
This PR consolidates duplicated list-output formatting across the CLI
into shared rendering infrastructure.
Currently, each list command has its own copy of the same
json/quiet/table branching. This PR pulls that into shared rendering
infrastructure in `ContainerCommands`:
- `ListDisplayable` protocol for table + quiet output
- `renderJSON`, `renderTable`, `renderList` as pure functions that
return strings
- `emit()` as the single stdout boundary (no-ops on empty strings to
avoid blank-line regressions)
- `JSONOptions` so all JSON encoding goes through one path, including
volume inspect's pretty + ISO 8601 case
JSON encoding remains separate from display formatting: each command
still chooses its own JSON model, while `ListDisplayable` is used only
for table and quiet output. `ImageList` remains the intentional
exception for quiet mode so it can avoid unnecessary async work.
This change also replaces inline `JSONEncoder` usage with `renderJSON`,
removes the old `Codable+JSON.swift` helper, and moves `TableOutput` and
`ListFormat` into `ContainerCommands`. It also adds unit tests for the
shared rendering helpers and expands integration coverage for image,
network, and registry list formatting.

This PR fixes `container build` to use docker specific ignore (#1169).
This PR relies on apple/container-builder-shim#68.
When docker specific ignore file is detected, it creates a hidden docker
directory (i.e., `.hidden-docker-dir`) under the build context, and
places Dockerfile and ignore file under there. This hidden directory is
passed to the builder shim and used by buildkit daemon to correctly
figure out the docker specific ignore file.
Docker specific ignore file is detected regardless of whether i) they
are under nested directory, ii) outside build context, iii) using custom
names. If docker specific ignore is not provided, hidden directory is
also not created, and buildkit daemon will use the docker ignore file at
build context root as usual.
## Type of Change

- Previously we weren't tolerating a throw from
the check.
- We have #1250 open for root cause analysis of
this particular throw that trips the test up.
This PR fixes#1277.
`SandboxService.waiters` had a consistency issue (not exactly race).
`SandboxService.wait` XPC can be executed on arbitrary `id`, and it will
hang forever if no other handler resumes it. Without knowing this
internal, the high level entity can run into this issue, and deadlock.
This PR simplifies the mental model: **`SandboxService.waiters[id]:
ExitWaiter(continuations, exitCode)` can only be in three states: i)
non-existing, ii) existing with nil `exitCode`, and iii) existing with
concrete `exitCode`.**
**If it is non-existing, no handler has been registered to resume it
later. If existing with nil `exitCode`, It is guaranteed the registered
`continuations` will be resumed later with a concrete `exitCode`.
Finally, if already a concrete `exitCode`, a handler has been
registered, and already resumed (with that `exitCode`).**
Thus, `SandboxService.wait` should return immediately if `waiters[id]`
is non-existing or existing with a concrete `exitCode` (as no handler
will resume it later). It should only block when `waiters[id]` is
existing with nil `exitCode` as it is guaranteed to be resumed later. By
doing so, we can guarantee there is no deadlock at all.
For that this PR does followings:
1. Introduce `ExitMonitor` class to updates `continuations` and
`exitCode` all together atomically. Initially, `state` variable saved
the `exitCode`, but it cannot be tied with `continuations` as they are
protected by different primitives (i.e., lock and actor).
2. Gather `waiters` related operations into a single actor method,
guaranteeing those are performed atomically under actor
protection---i.e., we actually don't need Mutex here.
3. Ensure initialized `waiters` are released (i.e., resumed) later
(under any possible circumstances).
4. Move `process.wait` after `process.start` in `io.handleProcess` to
run `SandboxService.wait` only after the `waiters[id]` is initialized.
By doing fourth step, we can guarantee `SandboxService.wait` can meet
only one of two following `ExitMonitor` state: i) existing with nil
`exitCode`, or ii) existing with concrete `exitCode` (in case the
process exited too early). In both cases, `exitCode` is preserved and
returned.

Fix container hang when starting an invalid executable (#1277).
Ensure the `SandboxService.waiters` updated atomically, preventing a slow `wait` from registering continuation after the `SandboxService` has been stopped.
Current `ProcessIO.handleProcess` has races between `process.wait()` and
`process.start()`. In `process.wait`, `SandboxService.wait` registers
and block on a continuation so that later exit of that `LinuxContainer`
can resume it.
Even if `SandboxService.wait` checks the container state, there can be a
race so that `SandboxService.startInitProcess` fails earlier with no
continuation to resume, then `SandboxService.wait` registers the
continuation, which forever hang the thread.
- Closes#1270.
- The current test is a bit baroque. It tries to run `nc`, either to
`8.8.8.8:53` or a proxy server port if `HTTP_PROXY` is in the
environment. It seems that for an alpine image, a proxy-aware
`Dockerfile` and a `RUN apk install curl` directive is a more natural
test of "network access".
Closes#1225
Add a flag to signify that we'd like to run a minimal init process that
can reap zombie processes. The actual support for this is in the
Containerization library so the plumbing here is very simple.
- 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`.
- 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.
## Type of Change
- [x] Bug fix

## 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.

## Type of Change

## 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.

- Closes#977.
- Closes#1058.
- Prevents unexpected removal of containers on
bootstrapping and starting failures, by reorganizing
error handling for container `run`, `start`, and
`exec` so that error handling only unwinds that
which was done in the current scope.
- Relies on apple/containerization#495.
- Closes#1037.
- Adds a `--mode` flag that has `nat` and `hostOnly` options.
The host-only option selects the vmnet host-only mode,
where containers attached to the network can reach each
other and the host, but not external systems.
- Runner fleet is on 26.3 now.
- Integration tests started flaking and it appears that we've been misconfiguring/not configuring proxy variables where we needed to be and it finally caught up with us. Workflow now adds appropriate exclusions for host-to-container and container-to-container network requests so they aren't all rammed through the proxy.
- Update image load and build to handle rejected paths during tar
extraction. For the image load command there is now a `--force` function
that fails extractions with rejected paths when false, and just warns
about the rejected paths when true.
- Update `container stats` for statistics API properties now all being
optional.
