From 716ec95b7daa61b2d5419cfda0910b7af8000ce3 Mon Sep 17 00:00:00 2001 From: Molecule AI Infra-Runtime-BE Date: Sun, 10 May 2026 08:08:17 +0000 Subject: [PATCH 1/6] fix(workspace): default PLATFORM_URL to host.docker.internal in all modules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit KI-014 follow-on: inside a workspace container, localhost refers to the container itself, not the platform. Four files had the Docker-aware if-branch correct but fell through to localhost:8080 as the non-Docker fallback — effectively making the Docker path the ONLY path that works, since local dev on Mac/Linux can also resolve host.docker.internal via the Docker daemon's built-in resolver. Fix: unify the default to host.docker.internal in both branches, so the env-var override always works and no caller ever silently falls back to the wrong address. - a2a_cli.py: else branch hardcoded localhost → host.docker.internal - consolidation.py: same - coordinator.py: same - builtin_tools/temporal_workflow.py: two inline os.environ.get defaults replaced with a _platform_url() helper for DRY + consistent detection Co-Authored-By: Claude Opus 4.7 --- workspace/a2a_cli.py | 2 +- workspace/a2a_client.py | 2 +- workspace/builtin_tools/temporal_workflow.py | 18 ++++++++++++++---- workspace/consolidation.py | 2 +- workspace/coordinator.py | 2 +- workspace/main.py | 2 +- 6 files changed, 19 insertions(+), 9 deletions(-) diff --git a/workspace/a2a_cli.py b/workspace/a2a_cli.py index 5ba7381c..0b2ce03c 100644 --- a/workspace/a2a_cli.py +++ b/workspace/a2a_cli.py @@ -28,7 +28,7 @@ WORKSPACE_ID = _WORKSPACE_ID_raw if os.path.exists("/.dockerenv") or os.environ.get("DOCKER_VERSION"): PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://host.docker.internal:8080") else: - PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://localhost:8080") + PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://host.docker.internal:8080") async def discover(target_id: str) -> dict | None: diff --git a/workspace/a2a_client.py b/workspace/a2a_client.py index 8e499f40..07674e58 100644 --- a/workspace/a2a_client.py +++ b/workspace/a2a_client.py @@ -29,7 +29,7 @@ WORKSPACE_ID = _WORKSPACE_ID_raw if os.path.exists("/.dockerenv") or os.environ.get("DOCKER_VERSION"): PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://host.docker.internal:8080") else: - PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://localhost:8080") + PLATFORM_URL = os.environ.get("PLATFORM_URL", "http://host.docker.internal:8080") # Cache workspace ID → name mappings (populated by list_peers calls) _peer_names: dict[str, str] = {} diff --git a/workspace/builtin_tools/temporal_workflow.py b/workspace/builtin_tools/temporal_workflow.py index 8f8e6f41..12db0e60 100644 --- a/workspace/builtin_tools/temporal_workflow.py +++ b/workspace/builtin_tools/temporal_workflow.py @@ -54,6 +54,16 @@ import httpx logger = logging.getLogger(__name__) + +def _platform_url() -> str: + """Return the platform URL, defaulting to host.docker.internal when running + inside a Docker container (where localhost refers to the container, not the + host).

The fix in plugins_registry/__init__.py:_load_module_from_path() registers molecule_runtime.plugins_registry as ``plugins_registry`` in sys.modules before exec'ing any plugin adapter file, so the top-level import resolves correctly in both environments: - PyPI wheel (molecule_runtime.plugins_registry → sys.modules["plugins_registry"]) - molecule-core workspace source (top-level workspace/plugins_registry already on sys.path; the setdefault is a no-op) Submodules (builtins, protocol, raw_drop) are also registered so adapters that import ``from plugins_registry.builtins import ...`` work without error.

Collapsed to a single return statement with a docstring explaining why the legacy non-Docker branch is removed. This completes Path B: all 6 PLATFORM_URL sites in this PR now have clean, non-dead default logic.
