roboco/docker/orchestrator.Dockerfile

# =============================================================================
# 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.
# =============================================================================

# own — otherwise the venv symlinks into /root/.local/share/uv/python/... and
# breaks when COPY --from=builder only copies /app.

# 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 '*'
