# Docker Compose Stacks Reference

Complete reference for all Docker Compose stacks in the portainer-core infrastructure.

## Deployment

See the [core-api OpenAPI documentation](http://localhost:8083/docs) for infrastructure management REST endpoints.

All stacks are located in the `/stacks/` directory and version-controlled.

## Storage Convention

All stacks follow the dual-disk strategy:

**SSD (Performance):**
- Configs: `/home/jpmschweitzer/docker-data/<service>/config`
- Cache: `/home/jpmschweitzer/docker-data/<service>/cache`
- Databases: `/home/jpmschweitzer/docker-data/<service>/db`

**HDD (Capacity):**
- User content: `/mnt/media/<service>/data`
- Media files: `/mnt/media/<service>/media`
- Backups: `/mnt/media/backups/<service>`

See [Shared Infrastructure Architecture](../architecture/SHARED_INFRASTRUCTURE_ARCHITECTURE.md) for database and cache sharing details.

## GPU Services

Stacks requiring GPU access (marked with **Yes** above):
- `ollama.yml` - ML model inference
- `jellyfin.yml` - Hardware transcoding

**Prerequisites:**
- NVIDIA Container Toolkit installed
- GPU verified: `docker run --rm --gpus all nvidia/cuda:11.4.0-base-ubuntu20.04 nvidia-smi`

See [GPU Docker Configuration](../guides/gpu-docker-config.md) for setup details.

## Deployment Checklist

### Before Deploying

1. **Review environment variables** - Change default passwords!
2. **Create directories** - Ensure volume paths exist
3. **Check ports** - Verify no conflicts with existing services
4. **GPU services** - Confirm NVIDIA toolkit installed
5. **Update STATUS.md** - Plan the deployment

### After Deploying

1. **Test service** - Access web UI or API endpoint
2. **Check logs** - `docker logs <container-name>`
3. **Verify GPU** - `docker exec <container> nvidia-smi` (if applicable)
4. **Update documentation** - Add to STATUS.md and CHANGELOG.md
5. **Configure backup** - Add to Duplicati backup job
6. **Add monitoring** - Configure Uptime Kuma checks

## Maintenance

### Update a Stack

```bash
# Pull latest images
docker compose -f stacks/<stack-name>.yml pull

# Recreate containers with new images
docker compose -f stacks/<stack-name>.yml up -d

# Or let Watchtower handle it automatically
```

### Backup Stack Configuration

Stacks are version-controlled in the `/stacks/` directory. Backup container data separately using the backup procedures.

See [Backup Procedures](../guides/backup-procedures.md) for details.

### Troubleshooting

- Container won't start: `docker logs <container-name>`
- Port conflicts: `sudo netstat -tulpn | grep <port>`
- Permission issues: Check volume path ownership
- GPU not detected: Verify NVIDIA toolkit and restart Docker

## Automation

The project includes automation scripts for stack management:

- `update-stack.sh` - Pull and update specific stack
- See [Automation Reference](AUTOMATION.md) for Portainer REST API usage
