# External render-worker configuration.
#
# Use this compose file on remote machines (GPU nodes, NAS, cloud VMs) that
# only need Redis + MinIO access — no database, no backend, no frontend.
#
# Usage on remote machine:
#   export REDIS_URL=redis://main-server:6379/0
#   export MINIO_URL=http://main-server:9000
#   export MINIO_USER=minioadmin
#   export MINIO_PASSWORD=minioadmin
#   docker compose -f docker-compose.worker.yml up -d
#
# Requirements on remote machine:
#   - Blender >= 5.0.1 installed at /opt/blender (or set BLENDER_BIN)
#   - Docker + GPU drivers (NVIDIA recommended)

services:
  render-worker:
    image: hartomat-render-worker:latest
    # Or build locally: build: { context: ./render-worker, dockerfile: Dockerfile }
