# Orchestrator — multi-stage build
# =============================================================================
# Builder stage compiles the Python venv; runner stage is slim Debian with
# docker-cli (needed to spawn agent containers over the mounted docker socket)
# and the pre-built venv copied in.

# pnpm lets the orchestrator pre-install the frontend/panel cell's workspace
# deps (`pnpm install`) the same way uv handles Python cells. Without it the
# dep-install step gracefully skips (WorkspaceService._run_dep_install catches
# the missing-tool OSError) and the fe-dev re-installs per task. node/npm come
# from the NodeSource layer above; pnpm matches how agent-dev-fe installs it.

# has it at /usr/local/bin/uv; carry it into the runner so it's on PATH.

# Orchestrator clones workspaces as root, then chowns them to the agent
# user (uid 1000) so the agent container can read/write. After the chown,
# the orchestrator (still root) needs to run git commands (claim branch
# creation, status, log, fetch) inside those now-1000-owned dirs — git's
# "dubious ownership" check refuses unless safe.directory is set. `*`
# trusts every path, which is fine here since this container only mounts
# the sandboxed /data/workspaces tree.
RUN git config --global --add safe.directory '*'

# PYTHONUNBUFFERED: flush stdout/stderr immediately so structured logs reach
# `docker logs` in real time. Without it Python block-buffers stdout (it's a pipe,
# not a TTY) and lines arrive in large delayed chunks — which made live log
# diagnosis impossible during the intake smoke tests.
