The first concrete LaunchBroker, proving the orchestrator -> backend seam
on the cheapest backend (the sidecar bundle is already containers):
* orchestrator/docker_broker.py — DockerBroker runs a container on a
verified launch (`docker run --detach --name <bottle> --label ...
<image_ref>`) and removes it on teardown (`docker rm --force`,
idempotent on an already-absent container). The argv is built only from
the request's static ids/flags, so nothing free-form reaches docker;
provenance/schema verification is inherited from LaunchBroker.submit.
* __main__.py gains `--broker {stub,docker}` so the harness can drive real
containers.
Slice 3 launches a single container from image_ref (the seam); the full
agent + sidecar bundle is a later slice.
Tests: unit (docker mocked) — argv from static fields, launch/teardown call
the right commands, missing-image and docker-failure raise, teardown
idempotent on missing, forged token never touches docker; integration
(gated on a reachable daemon) — launch creates a real container, teardown
removes it. Full suite green (only pre-existing /bin/sleep errors);
integration verified locally against real docker.

"""Run the orchestrator control plane as a plain process (PRD 0070 dev-harness).
|
|
|
|
python -m bot_bottle.orchestrator [--host H] [--port P] [--db PATH]
|
|
|
|
The PRD sequences the orchestrator as a plain-process dev-harness first, so
|
|
the consolidation core (registry + attribution + HTTP control plane + live
|
|
reload) can be exercised with fast iteration, decoupled from any VM /
|
|
container packaging. Wrapping this exact service in a backend-native unit
|
|
(docker container, then Firecracker VM) comes later.
