- Implement multi-server Traefik + Sablier architecture - Add label-based automatic service discovery - Create separate Sablier stack deployment - Add remote server deployment workflow (Option 3) - Add 9 new functions for multi-server management - Remove deprecated config-templates folder - Replace hardcoded private data with placeholders - Update backup timestamp format to YY_MM_DD_hh_mm - Add markup.yml to .gitignore Breaking changes: - Removed Sablier from core docker-compose.yml (now separate stack) - Config templates moved from config-templates/ to docker-compose/core/ - REQUIRED_VARS now dynamic based on deployment type

# Sablier Stack
|
|
|
|
This stack deploys [Sablier](https://github.com/acouvreur/sablier), a service that provides lazy loading (on-demand startup) for Docker containers.
|
|
|
|
## Overview
|
|
|
|
Sablier monitors Docker containers and can automatically start them when they receive traffic through Traefik, then stop them after a period of inactivity. This is useful for:
|
|
- Reducing resource usage on servers with limited RAM/CPU
|
|
- Managing seasonal or infrequently-used services
|
|
- Extending the capacity of small servers (like Raspberry Pi)
|
|
|
|
## Multi-Server Architecture
|
|
|
|
Each server in your homelab should have its own Sablier instance:
|
|
- **Core Server**: Manages lazy loading for core services
|
|
- **Remote Servers**: Each runs Sablier to control local containers
|
|
|
|
Sablier only connects to the local Docker socket (`/var/run/docker.sock`) on its own server.
|
|
|
|
## Features
|
|
|
|
- **Web Dashboard**: Access at `https://sablier.yourdomain.duckdns.org`
|
|
- **Protected by Authelia**: SSO authentication required
|
|
- **Local Control**: Only manages containers on the same server
|
|
- **Traefik Integration**: Uses Traefik middlewares for automatic container startup
|
|
|
|
## Usage
|
|
|
|
### Enable Lazy Loading on a Container
|
|
|
|
Add these labels to any service in your docker-compose files:
|
|
|
|
```yaml
|
|
services:
|
|
myservice:
|
|
image: myapp:latest
|
|
labels:
|
|
- "traefik.enable=true"
|
|
- "traefik.http.routers.myservice.rule=Host(`myservice.yourdomain.duckdns.org`)"
|
|
- "traefik.http.routers.myservice.entrypoints=websecure"
|
|
- "traefik.http.routers.myservice.tls=true"
|
|
- "traefik.http.routers.myservice.middlewares=sablier-myservice@docker"
|
|
|
|
# Sablier middleware configuration
|
|
- "traefik.http.middlewares.sablier-myservice.plugin.sablier.names=myservice"
|
|
- "traefik.http.middlewares.sablier-myservice.plugin.sablier.sablierUrl=http://sablier:10000"
|
|
- "traefik.http.middlewares.sablier-myservice.plugin.sablier.sessionDuration=5m"
|
|
```
|
|
|
|
### Configuration Options
|
|
|
|
- `names`: Container name(s) to manage (comma-separated for multiple)
|
|
- `sablierUrl`: URL of the Sablier service (use `http://sablier:10000` for local)
|
|
- `sessionDuration`: How long to keep the container running after last request (e.g., `5m`, `1h`)
|
|
|
|
## Deployment
|
|
|
|
This stack is automatically deployed:
|
|
- On the **core server** after core infrastructure deployment
|
|
- On **remote servers** during remote server setup
|
|
|
|
Manual deployment:
|
|
```bash
|
|
cd /opt/stacks/sablier
|
|
docker compose up -d
|
|
```
|
|
|
|
## Resources
|
|
|
|
- CPU: ~10-20 MB RAM per instance
|
|
- Storage: Minimal (~50 MB)
|
|
- Network: Internal Docker network only
|
