# Docker Compose configuration for DEPLOYMENT with pre-built images
#
# IMPORTANT: This configuration is designed for deployment scenarios where you have
# already built and pushed your Docker images to a container registry.
#
# Since this is a template project, you'll need to:
# 1. Build your images: docker-compose build
# 2. Tag them appropriately: docker tag <image> <your-registry>/<your-project>:<tag>
# 3. Push to your registry: docker push <your-registry>/<your-project>:<tag>
# 4. Update the image references below to point to your registry
#
# Example registry paths:
# - Docker Hub: username/project-backend:latest
# - GitHub Container Registry: ghcr.io/username/project-backend:latest
# - GitLab Registry: registry.gitlab.com/username/project/backend:latest
# - Private Registry: registry.example.com/project-backend:latest
