"""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.
|
|
|
|
Per PRD 0050 the per-provider provisioning steps (prompt, skills,
|
|
the declarative provision-plan apply, supervise MCP registration)
|
|
live on the `AgentProvider` plugin under `bot_bottle/contrib/`. The
|
|
Docker backend only owns the steps that are about backend
|
|
infrastructure: CA install and git copy-in.
