# =============================================================================
# VideoPress — docker-compose.yml
# =============================================================================
#
# Quick start:
#   1. Edit MEDIA_HOST_PATH below (or set it as a shell variable before running)
#   2. docker compose up -d
#   3. Open http://localhost:8080
#
# All configuration lives in the 'environment' section — no .env file needed
# for basic usage, though a .env file is supported (see comments below).
# =============================================================================

services:
  videopress:
    build:
      context: .
      dockerfile: Dockerfile

    # ── Alternatively, use a pre-built image: ───────────────────────────────
    # image: videopress:latest

    container_name: videopress

    # Run as UID:GID 1000:1000 (matches the 'appuser' created in the Dockerfile).
    # This ensures the container can write to bind-mounted host directories
    # that are owned by UID 1000.
    user: "1000:1000"

    restart: unless-stopped

    # ── Port mapping ─────────────────────────────────────────────────────────
    # Format: "HOST_PORT:CONTAINER_PORT"
    # The UI and REST API are served on the same port — no separate API port
    # is required.  Change the host port (left side) as needed.
    ports:
      - "8080:8080"

    # ── Volume mapping ────────────────────────────────────────────────────────
    # Map the directory on your HOST that contains the video files into the
    # container at /media (MEDIA_ROOT).
    #
    # *** Change /path/to/your/videos to the real path on your host. ***
    #
    # You can also set MEDIA_HOST_PATH as an environment variable before
    # running docker compose:
    #   export MEDIA_HOST_PATH=/mnt/nas/videos && docker compose up -d
    #
    # IMPORTANT — before first run, create the data directory on the HOST
    # and give it to UID 1000 (the container's non-root user) so SQLite can
    # write the settings database:
    #
    #   mkdir -p ./data
    #   chown 1000:1000 ./data
    #
    # If you skip this step Docker will create ./data as root and the
    # container will fail to start with "unable to open database file".
    volumes:
      - ${MEDIA_HOST_PATH:-/path/to/your/videos}:/media
      - ./data:/data

    # ── Environment variables ─────────────────────────────────────────────────
    environment:
      # Path *inside the container* where videos are accessible.
      # Must match the right-hand side of the volume mount above.
      MEDIA_ROOT: /media

      # SQLite database path inside the container.
      # Must match the right-hand side of the ./data:/data volume mount.
      DB_PATH: /data/videopress.db

      # TCP port Gunicorn listens on (must match EXPOSE in Dockerfile and
      # the right-hand side of the ports mapping above).
      PORT: 8080

      # Gunicorn log level: debug | info | warning | error | critical
      LOG_LEVEL: info

    # ── Resource limits (optional — uncomment to enable) ─────────────────────
    # Compressing large video files is CPU-intensive.  Limits prevent the
    # container from starving other workloads on the host.
    # deploy:
    #   resources:
    #     limits:
    #       cpus: '4'
    #       memory: 2G
    #     reservations:
    #       cpus: '1'
    #       memory: 512M
