docker.py DOX

Purpose

• Own the docker.py helper module.
• This module manages Docker container operations used by runtime helpers.
• Keep this file-level DOX profile synchronized with docker.py because this directory is intentionally flat.

Ownership

• docker.py owns the runtime implementation.
• docker.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• DockerContainerManager (no explicit base class)
  • init_docker(self)
  • cleanup_container(self) -> None
  • get_image_containers(self)
  • start_container(self) -> None

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem deletion, subprocess/runtime control, WebSocket state.
• Imported dependency areas include: atexit, docker, helpers.errors, helpers.files, helpers.log, helpers.print_style, time, typing.

Key Concepts

• Important called helpers/classes observed in the source: self.init_docker, PrintStyle.standard, self.client.containers.run, time.sleep, docker.from_env, self.container.stop, self.container.remove, existing_container.start, self.logger.log, format_error, PrintStyle.error, PrintStyle.hint.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_browser_agent_regressions.py
  • tests/test_default_prompt_budget.py
  • tests/test_docker_release_plan.py
  • tests/test_document_query_plugin.py
  • tests/test_host_browser_connector.py
  • tests/test_model_search.py
  • tests/test_office_canvas_setup.py
