New Dockerfile.sidecars multi-stage build: pulls the pinned
pipelock and gitleaks binaries into a mitmproxy-base final image,
installs git + openssh-client, and ships the project's egress
addon + supervise server alongside a stdlib-Python init at
/app/sidecar_init.py.
The init supervisor (claude_bottle/sidecar_init.py) is PID 1 in
the bundle. It spawns the daemons named in
CLAUDE_BOTTLE_SIDECAR_DAEMONS (or all four by default),
propagates SIGTERM/SIGINT to children with an 8s grace before
SIGKILL, and exits with the first-unexpected-child exit code so
a daemon crash tears down the bundle (per PRD 0024 open
question 1's default).
claude_bottle/egress_entrypoint.sh extracted verbatim from
Dockerfile.egress's prior inline sh -c so the supervisor can
call it as a normal child.
Tests:
- unit: _selected_daemons env-var subset behavior (7 cases),
_Supervisor signal/exit-code semantics including SIGKILL
escalation, and end-to-end main() via subprocess.
- integration: builds the image and probes that pipelock,
gitleaks, mitmdump, and the supervise Python module are
present + executable, plus a no-daemons-selected smoke test
of the entrypoint wiring. Skipped under act_runner (200+MB
base pulls + multi-stage build).
Renderer collapse and the deletion of Dockerfile.{egress,git-gate,
supervise} land in chunk 2 + 3.
