Stage 2 of the docker-free Firecracker backend (#348): stop building the fixed infra image on the launch host. The infra VM's rootfs is host- and bottle-agnostic (authorized_keys + guest IP ride the kernel cmdline, not the rootfs), so it's built once off-host and published as a versioned, ready-to- boot ext4; the launch host downloads + verifies + boots it — no Docker, no image tooling, just HTTP + gunzip. - infra_artifact.py: version = content hash of the rootfs inputs (the shipped bot_bottle package + the three Dockerfiles + the init), so a launch host pulls the artifact matching its code and a content change can't silently boot a stale rootfs. Pull + sha256-verify (fail-closed) + gunzip from a Gitea generic package; base/owner/token configurable, default this Gitea. - infra_vm.ensure_built/boot default to the pull path; BOT_BOTTLE_INFRA_BUILD= local keeps the docker build-from-source path for iterating on Dockerfiles. - publish_infra.py: the off-host half — builds the images with Docker, mke2fs the rootfs (with buildah slack), gzips, and PUTs it to the generic package. Rollout note: default=pull means a launch 404s until an artifact is published; until the Gitea packages endpoint is enabled + an artifact published, use BOT_BOTTLE_INFRA_BUILD=local. Freeze/migrate's remaining docker use is a separate PR. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UoEZHDjv84ChoZbozQERhJ
Tests
Plain-Python test suite using stdlib unittest. No external
dependencies. Unit tests run anywhere Python 3 is present; integration
tests need Docker and skip cleanly otherwise.

Classification falls out of the directory — no hand-maintained list to keep in sync.
Running
python -m unittest discover -t . -s tests/unit -v # unit only
python -m unittest discover -t . -s tests/integration -v # integration only
python -m unittest discover -t . -s tests -v # both (recursive)
python -m unittest tests.unit.test_manifest_egress # one file
Discovery is invoked with -t . (top-level dir = repo root) so the
bot_bottle package on sys.path resolves correctly.
What the integration tests cover
test_dry_run_plan.py—cli.py start --dry-run --format=jsonemits a structured plan that contains the resolved egress allowlist and the bottle's runtime, and creates zero Docker resources.test_orphan_cleanup.py—network_removeis idempotent against missing resources, so the EXIT trap can call it unconditionally.test_gateway_image.py— builds Dockerfile.gateway and probes that gitleaks / mitmdump / supervise are all reachable inside the gateway image.
Canaries
tests/canaries/ holds upstream-regression checks gated on
BOT_BOTTLE_RUN_CANARIES=1 and not part of the per-push suite.
They're invoked by the scheduled canaries workflow. Currently
no canaries are defined.
BOT_BOTTLE_RUN_CANARIES=1 python -m unittest discover -t . -s tests/canaries -v
What's NOT covered
bot_bottle/ssh.pyend-to-end (would need a fake SSH host inside the container).- A live SSH-through-git-gate tunnel against a real Tailscale-style IP.
- DLP false-positive measurements.
- TLS handling / cert pinning behavior.
Adding a test
- Pick the directory:
tests/unit/for a pure unit test,tests/integration/for one that needs Docker. - Filename:
test_<topic>.py. - Boilerplate:
import unittest from bot_bottle.<module> import <symbol> class TestThing(unittest.TestCase): def test_x(self): ... if __name__ == "__main__": unittest.main() - For Docker-dependent tests, decorate the class with
@skip_unless_docker()fromtests._docker.
