"""DockerBottleBackend — the Docker implementation of BottleBackend.
|
|
|
|
This module is a thin façade. The real work lives in four siblings:
|
|
|
|
- prepare.py — host-side resolution into a DockerBottlePlan
|
|
- launch.py — bring-up + teardown context manager
|
|
- cleanup.py — orphan enumeration + removal
|
|
- enumerate.py — active-agent listing
|
|
|
|
The base class's `prepare` template runs cross-backend host-side
|
|
validation before calling `_resolve_plan` here.
