Adds `./cli.py commit [<slug>]` which runs `docker commit` on the active agent container and stores the resulting image tag in per-bottle state. The next `./cli.py resume <slug>` automatically boots from the committed snapshot instead of rebuilding from the Dockerfile, preserving all in-container state across restarts and migrations. - bottle_state: add write_committed_image / read_committed_image helpers - docker/util: add commit_container wrapper around `docker commit` - docker/launch: check for a committed image before the Dockerfile build step; fall back to normal build if the image is absent from the daemon - cli/commit: new command with interactive slug picker; errors clearly on non-Docker backends - 50 new unit tests covering all paths Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

"""Launch step for the Docker bottle backend.
|
|
|
|
PRD 0018 chunk 3: each instance is one `docker compose` project.
|
|
|
|
The flow is:
|
|
|
|
1. Build the agent image from the provider Dockerfile (compose
|
|
builds the sidecar images via the `build:` directive on first up).
|
|
2. Mint the per-bottle egress CA (chunk 2 writes it under
|
|
state/<slug>/egress/).
|
|
3. Populate the inner plans with launch-time fields so the
|
|
renderer can read network names, CA paths.
|
|
6. Render the compose spec, write it to
|
|
state/<slug>/docker-compose.yml, write metadata.json.
|
|
7. `docker compose up -d` (token + OAuth values flow into the
|
|
compose subprocess env so `environment: [NAME]` bare-name
|
|
entries inherit without rendering values into the file).
|
|
8. Provision (CA install, prompt copy, skills, workspace, git,
|
|
supervise config) — unchanged, uses `docker exec` / `docker cp`.
|
|
9. Yield a DockerBottle handle. `exec_agent` runs claude via
|
|
`docker exec -it` exactly like the pre-compose world.
|
|
|
|
Teardown (ExitStack callbacks fire in reverse):
|
|
- Dump `docker compose logs --no-color --timestamps` to
|
|
state/<slug>/compose.log (best-effort).
|
|
- `docker compose down` removes the project's containers (not the
|
|
external networks).
|
|
- `network_remove` deletes the two networks we pre-created.
