# ============================================
# DeepTutor Docker Compose Configuration
# ============================================
# This file provides orchestration for DeepTutor services
#
# Usage:
#   Production:  python scripts/docker_compose.py up -d
#   Development: python scripts/docker_compose.py -f docker-compose.yml -f docker-compose.dev.yml up
#   Build only:  python scripts/docker_compose.py build
#
# Prerequisites:
#   1. Runtime settings are stored in ./data/user/settings (created automatically)
#   2. Configure model providers from the web Settings page or model_catalog.json
#   3. Use scripts/docker_compose.py so port mappings are rendered from system.json
#
# Local LLM (LM Studio / Ollama / vLLM):
#   Use "host.docker.internal" instead of "localhost" in provider base_url fields.
#   Configure provider endpoints in data/user/settings/model_catalog.json or the UI.
# ============================================

  # PocketBase — optional auth + storage sidecar
  # Set integrations.pocketbase_url=http://pocketbase:8090 to activate.

  # ============================================
  # Sandbox Runner Sidecar
  # ============================================
  # Executes untrusted shell commands in an isolated, least-privileged
  # container so the main app never has to. Rationale for the sidecar shape:
  #   * the main `deeptutor` container keeps minimal privileges and does NOT
  #     mount the docker socket or run untrusted code in its own process;
  #   * a sandbox escape here lands in a stripped, unprivileged container with
  #     no app secrets, not in the main app.
  # Not exposed to the host: it is reachable only on the internal
  # deeptutor-network at http://sandbox-runner:8900.

    # Share the task workspaces at the SAME paths as the main app so the mount
    # contract holds: a request with host_path == sandbox_path under
    # /app/data/user/workspace (admin) or /app/data/users/<uid> (per-user)
    # is already visible here, no per-command mounting needed.
    # Scope note: every command in this container shares one filesystem view
    # (per-command isolation is a roadmap item), so the mounts are kept as
    # narrow as the exec feature allows — workspace subtrees only. Secrets
    # (data/system, data/user/settings) never enter this container; the
    # residual exposure is cross-user visibility *between user workspaces*,
    # acceptable for the invite-only trust posture and enforced no further.
