"""Per-bottle sidecar bundle bringup for the smolmachines backend
|
||||
(PRD 0023).
|
||||
|
||||
Two docker resources per bottle live here:
|
||||
|
||||
- **A dedicated bridge network**, subnet derived from the slug.
|
||||
The bundle container gets a pinned IP at `<subnet>.2` so the
|
||||
smolvm guest's TSI allowlist (`<bundle-ip>/32`) has a stable
|
||||
target. Without pinning, we'd have to inspect the container's
|
||||
assigned IP after start and feed it back into the Smolfile
|
||||
— a race we can sidestep with `--ip`.
|
||||
|
||||
- **The bundle container itself**, running the PRD 0024 bundle
|
||||
image (`bot-bottle-sidecars:latest` by default). Same
|
||||
image, same daemons, same daemon-private env / bind-mounts
|
||||
as the docker backend.
|
||||
|
||||
This module ships the lifecycle primitives only — create
|
||||
network, start bundle, stop bundle, remove network — wrapped
|
||||
around `subprocess.run(["docker", ...])`. Wiring them into the
|
||||
launch flow + populating the `BundleLaunchSpec` from the inner
|
||||
Plans (PipelockProxyPlan, EgressPlan, …) lands in chunk 2d."""
