Summary

Remove local Dockerfile and build-context handling from openshell sandbox create --from.
Users now build and tag an image with the container engine used by their gateway, then pass that image reference to --from.

Related Issue

3098

Changes

  • Remove CLI-side Dockerfile detection and image building.
  • Remove the no-longer-needed bootstrap image-build implementation and dependencies.
  • Return a message with actionable guidance when --from receives an explicit local path.
  • Update custom-image E2Es to build test images explicitly through the active container engine.
  • Update documentation, examples, agent scripts, and troubleshooting guidance for the image-first workflow.
  • Make agent launcher query gateway driver, then build image in matching Docker or Podman store.
  • Reject CONTAINER_ENGINE mismatch and unsupported gateway drivers before build.
  • Update CLI and gator agent skills for explicit image builds and gateway-selected container engines.

Testing

  • mise run pre-commit passes
  • mise run e2e passes
  • Unit tests added/updated
  • E2E tests added/updated (if applicable)

Checklist

  • Follows Conventional Commits
  • Commits are signed off (DCO)
  • Architecture docs updated - not applicable

Summary by CodeRabbit

  • Changes

    • openshell sandbox create --from accepts container image references and community sandbox names; local Dockerfiles and directories are no longer accepted directly.
    • Build and tag custom images with Docker or Podman before creating a sandbox.
    • Remote gateways require custom images to be available from an accessible registry.
    • Image preparation now follows the gateway’s configured container engine.
  • Documentation

    • Updated setup, troubleshooting, and BYOC guidance with local build, tagging, engine compatibility, and registry workflows.

📝 Walkthrough

Walkthrough

The CLI no longer builds local Dockerfiles during sandbox creation. Launchers build images with the gateway-selected Docker or Podman engine, and E2E tests use shared image-build helpers. Documentation now describes pre-built image workflows.

Changes

Pre-built Image Workflow

Layer / File(s) Summary
CLI image resolution and local build removal
crates/openshell-cli/..., crates/openshell-bootstrap/Cargo.toml
--from now resolves images or community sandboxes. Local paths return external build guidance. The local image builder and related dependencies were removed.
Gateway engine selection and launcher image preparation
scripts/agents/..., .agents/skills/launch-openshell-gator/SKILL.md
Launchers query the gateway driver, validate Docker or Podman compatibility, build staged images, and pass image tags to sandbox creation.
Shared E2E image build helper and test migration
e2e/rust/src/harness/container.rs, e2e/rust/tests/...
ImageGuard builds and cleans up uniquely tagged images. E2E tests use the generated tags.
Image workflow documentation
README.md, docs/..., examples/..., skills/..., deploy/..., rfc/...
Documentation describes local Docker or Podman builds and registry requirements for remote gateways.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to ea94b

Users passing a Dockerfile path may receive a build command that fails or builds the wrong file. This is a bounded workflow issue.

1169-1170: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Implicit path detection makes --from resolution depend on the working directory.

value_looks_like_local_path returns true when a file or directory with the same name exists in the current directory. A bare image or community name is then rejected. openshell sandbox create --from python fails when the current directory contains a python/ directory, and --from python is a documented example in main.rs (SANDBOX_EXAMPLES). The error text states that --from no longer builds local Dockerfiles, which does not describe this case, and it offers no way to force image interpretation.

Consider limiting rejection to explicit path syntax (absolute, ., .., ./, ../, ~/), or keep the existence check and name the ambiguity in the error message.

♻️ Option: report the ambiguity explicitly
     if value_looks_like_local_path(value) {
+        let ambiguous = !(path.is_absolute()
+            || matches!(value, "." | "..")
+            || value.starts_with("./")
+            || value.starts_with("../")
+            || value.starts_with("~/"));
         let build_context = if path.is_dir() {

Then add a line to the error when ambiguous is true, telling the user that a local file or directory shares this name and that an explicit image reference (for example docker.io/library/python:3.12) avoids the collision.

1145-1152: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Include -f in the build guidance when the value points at a file.

The error prints the parent directory as the build context. If the user passed a Dockerfile with a non-default name, or a Dockerfile in a directory that has no Dockerfile, the suggested command builds the wrong file or fails. Add -f <path> when the value is not a directory.

Could we retain detection of bare Dockerfile names here? --from Dockerfile was previously supported, but the new path check only recognizes explicit paths such as ./Dockerfile. A bare Dockerfile will now be expanded as a community image and fail during image pull instead of returning the migration guidance.

openshell-byoc is a bare name, so --from will expand it as a community sandbox rather than use the locally built image. Could the example use openshell-byoc:latest for Docker and localhost/openshell-byoc:latest for Podman?

This assertion now accepts any provisioning-time container exit, which no longer proves the test’s working-directory authority invariant. Can we preserve an assertion tied to the workspace/WorkingDir rejection, or improve the surfaced error so the test can distinguish this failure from an unrelated container crash?

* feat(mxc): ETW->OCSF audit consumer + Windows OCSF JSONL parity (cp6 P1)

Add a Windows MXC ETW->OCSF audit trail in openshell-driver-mxc: a real-time
Sandboxing-provider ETW consumer that decodes events (TDH), attributes each to
an OpenShell sandbox_id, and maps them to OCSF (lifecycle 6002, config 5019,
process 1007, finding 2004).

cp6 Phase 1 - durable OCSF JSONL audit-file parity with Linux:
- openshell-ocsf: add emit_ocsf_event_routed (populates the event-bridge
  thread-local AND stamps sandbox_id+message in one dispatch) plus public
  set/clear_current_event; OS-aware device (Device::windows/for_current_os) so
  device.os.name reflects the host instead of a hardcoded Linux stub.
- etw_consumer: emit via the routed emit (previously fired a bare info! that
  never populated the bridge, so the structured event was dropped).
- openshell-server: install OcsfJsonlLayer over a synchronous daily-rotated
  appender (durable under force-kill), gated by OPENSHELL_OCSF_JSON, path via
  %PROGRAMDATA%\OpenShell\logs (override OPENSHELL_OCSF_LOG_DIR).
- device.hostname now resolves to the real gateway machine name.

Box-proven on 7F203-MXC-001: JSONL lines == shorthand OCSF rows, all valid
OCSF JSON, per-sandbox attribution intact, disabled state writes nothing.

Signed-off-by: Akber Raza <akberr@nvidia.com>

* feat(mxc): map remaining Sandboxing ETW events to OCSF

Close the last three ETW->OCSF gaps so the audit trail covers the full
set of events the Sandboxing provider emits (12/12):

- ProcessLaunched -> Process Activity [1007] "Launch" (confirmed start;
  carries the real processId/threadId, the twin of CreateProcessInSandbox
  which only has the request + command line).
- SandboxProxyConfigured -> Device Config State Change [5019] (the one
  network-plane setup event; surfaces proxyPort, "no proxy" when 0).
- SandboxConsoleReferencePlumbed -> Device Config State Change [5019]
  (console-handle plumbing).

map_config_state now handles the full config/hardening/setup family and
carries proxyPort/hasConsoleReference/creationFlags as unmapped fields.
Verified on 7F203-MXC-001: 11/12 event types emit OCSF without a proxy
(SandboxProxyConfigured requires proxy config to fire).

* fix(mxc): seed ETW attribution under registry lock + Device tests

Address CodeRabbit review on !31:

- Prevent stale ETW attribution on a delete/launch race: register the
  wxc-exec pid while holding the registry lock, and bail if the sandbox
  entry is already gone. Previously the attribution key could be seeded
  after `delete` had removed the sandbox, leaving a stale key that could
  misroute later Sandboxing ETW events to a dead sandbox_id. Lock order
  (registry -> attribution) matches the delete path, so no deadlock.
- Add unit tests for the new Device::windows and Device::for_current_os
  constructors to harden Windows/Linux OCSF device parity.

Signed-off-by: Akber Raza <akberr@nvidia.com>

* fix(mxc-etw): buffer+replay racing events and harden attribution keys

Addresses two ETW->OCSF attribution review items (Shailendra #1, #2).

#2 early-event loss: ETW delivers the sandbox create/config burst the instant wxc-exec starts, which can beat the driver's register_launch (now under the registry lock post-Ready). process_event previously dropped anything unresolved, losing the racing burst. Add a bounded, time-bounded pending buffer (PENDING_MAX=4096, PENDING_TTL=5s): unresolved events are held and replayed once attribution lands, aged-out ones dropped. Consumer switched to a timed recv_timeout(200ms) so the buffer is re-driven after each event and on a tick. Emit path factored into shared emit_resolved().

#1 attribution collisions: a Windows PID is recycled after exit and a command line is commonly identical across sandboxes. register_launch now rebinds by_pid on reuse and clears the stale last_pid_sid hint (warns if the PID still pointed at a different, leaked sandbox); command line is held in by_cmd only while unique and demoted to a new ambiguous_cmds set on a second owner, so a duplicate command refuses to resolve rather than misroute.

Unit tests: buffer replay (direct + cross-link), buffer bound, PID-reuse rebind, duplicate-cmd non-resolution. Box-verified on 7F203-MXC-001 (5 sandboxes, identical cmd -> 5 isolated sandbox_ids, 50/50 OCSF/JSONL, BuffersLost=0).

* docs(mxc-etw): note cmd_line is captured raw with no privacy filtering

Review item #3 (Shailendra): add a PRIVACY NOTE on map_process_launch stating cmd_line is copied verbatim into OCSF process.cmd_line with no redaction, so secrets/PII on a command line land unredacted in the durable audit trail (deliberate audit-fidelity trade-off; treat the log as sensitive). Redaction is owned by an upstream privacy layer, not this path; no general audit-output PII scrubber exists today (openshell_core::secrets [CREDENTIAL] redaction is scoped to the proxy HTTP-target logging, a separate egress path).

* fix(mxc-etw): open ETW trace on caller thread so start_session reports real status

Review item #4 (Shailendra): start_session previously returned Ok(EtwSession) as soon as the pump thread was spawned, but OpenTraceW ran later inside that thread; if it failed we still handed back a live-looking session and logged 'consumer started' (silent failure = false audit coverage).

Split the two Win32 calls instead of adding a channel handshake (avoids any lost-wakeup/hang risk): the quick, synchronous OpenTraceW now runs on the caller thread (open_trace), and only the blocking ProcessTrace runs on the pump thread (run_trace). start_session returns Err if OpenTraceW fails (reclaiming the boxed Sender so the consumer disconnects, stopping the session, joining the consumer) and returns Ok/logs 'started' only once capture is genuinely open. Opened handle + LoggerName buffer + boxed Sender are carried to the pump via a Send OpenedTrace so they outlive ProcessTrace.

Box-verified on 7F203-MXC-001: consumer started=True, failed-to-start=False, 50 OCSF rows / 50 JSONL, BuffersLost=0 (no regression to capture/emit).

* fix(mxc-etw): guard pending-event replay against PID recycling

CodeRabbit flagged that drain_resolved() re-resolved buffered events
against the live by_pid map, so if Windows recycled a wxc-exec PID within
PENDING_TTL a stale event from the dead sandbox could be emitted under the
new owner.

Stamp each by_pid registration with its Instant and add resolve_replay(),
used only on the buffered/replay path. It (a) never falls back to the
recycle-/ambiguity-prone by_cmd or last_pid_sid keys, and (b) trusts a PID
match only when the registration is not newer than the buffered event by
more than REPLAY_PID_GRACE (2s) - a recycled PID's registration lands well
outside that window, so the stale event ages out instead of misattributing.
The legitimate #2 seed race (registration lands ~immediately) still replays.

Adds unit tests for the recycle-refusal, in-grace acceptance, and
weak-fallback exclusion.

* fix(mxc-etw): surface unexpected ProcessTrace termination (review #4)

start_session already returns Err on OpenTraceW failure (runs on the
caller thread since e41a770), closing the first half of Shailendra's #4.
This closes the second half: ProcessTrace's result was discarded, so if
capture died mid-run the backend had no way to know.

Add a shared CaptureHealth (stopped/stopping/exit_code) between the pump
thread and EtwSession. run_trace now records ProcessTrace's WIN32_ERROR
and, when the pump returns without a deliberate stop, logs at ERROR that
MXC OCSF capture is no longer running. EtwSession::stop() sets `stopping`
before teardown so a normal shutdown isn't misreported, and
EtwSession::is_capture_alive() exposes the state for status/diagnostics.

Box-verified on 7F203-MXC-001: 5 sandboxes, 50 attributed OCSF rows,
JSONL parity 50/50, BuffersLost=0, clean start/stop (no false failure).

* feat(mxc-ocsf): add ETW->OCSF audit-trail example kit; fix proxy-configured message

Add a runnable OCSF audit-trail example under examples/ (run-ocsf-audit.ps1,
mxc-ocsf-audit.toml, ocsf-audit.yaml, README) that spins up sandboxes with the
in-process ETW consumer and egress proxy on, emitting a full OCSF JSONL audit
trail across all four classes (6002/5019/1007/2004).

Fix SandboxProxyConfigured mapping to log "MXC sandbox proxy configured" instead
of a misleading "(no proxy)" when the provider reports proxyPort=0; the event's
presence already indicates proxy configuration. Verified on-box: 26 events, all
mapped ETW event types present.

* feat(mxc-ocsf): clearer audit report + client-safe run-ocsf-audit.ps1

Improve the ETW to OCSF audit-trail example output and make it safe to ship.

Report:
- Add an event-type coverage count ("N of M expected event types fired");
  the denominator auto-adjusts (8 with proxy on, 7 with -NoProxy).
- Split the checklist into expected event types vs anomaly findings
  (ActivityError/FallbackError), which are reported separately and not
  counted toward coverage (a clean run may emit none).
- Verdict is now coverage-based (all expected types must fire) instead of
  the looser "at least 3 OCSF classes".
- Call out the absolute path to the durable OCSF JSONL log prominently.

Client-safety:
- Default -ShareOut to empty (no auto-copy); pass -ShareOut a UNC path to
  opt in. Removes a hardcoded internal share path from a published example.
- Drop internal-team wording ("Hand that zip back for evaluation", "BUNDLE:")
  in favor of neutral "Results bundle:".
- Update README-ocsf-audit.txt to match the opt-in -ShareOut behavior.

Verified on both MXC boxes: 7F203-MXC-001 (base-container) -> PASS, 8 of 8
event types, 26 OCSF events across 4 classes; 7F203-MXC-003 (AppContainer
fallback) -> reduced set as expected, clean output.
