+## Coolify Deployment
+
+This application can be deployed on [Coolify](https://coolify.io) using Docker Compose. Coolify provides additional features and management capabilities for containerized applications.
+
+### Coolify Prerequisites
+
+- Coolify instance (self-hosted or cloud)
+- Git repository accessible to Coolify
+
+### Coolify-Specific Configuration
+
+#### 1. Environment Variables
+
+Coolify automatically detects environment variables in your `docker-compose.yml` and provides a UI to manage them. Use the following syntax for better integration:
+
+```yaml
+services:
+  jobs-app:
+    environment:
+      # Required variables (will show red border if empty)
+      - FLASK_SECRET=${FLASK_SECRET:?}
+
+      # Required with default (prefilled but editable)
+      - FLASK_ENV=${FLASK_ENV:?production}
+
+      # Optional with default
+      - GUNICORN_WORKERS=${GUNICORN_WORKERS:-4}
+```
+
+#### 2. Coolify Magic Environment Variables
+
+Leverage Coolify's dynamic environment variables:
+
+```yaml
+services:
+  jobs-app:
+    environment:
+      # Generate FQDN for the application
+      - SERVICE_FQDN_JOBS_APP
+
+      # Generate secure password for admin user
+      - ADMIN_PASSWORD=${SERVICE_PASSWORD_ADMIN:?M11ffpgm.}
+
+      # Generate database credentials
+      - DB_USER=${SERVICE_USER_DB:?jobs}
+      - DB_PASSWORD=${SERVICE_PASSWORD_DB:?jobdb}
+```
+
+#### 3. Storage Configuration
+
+Coolify supports advanced storage options:
+
+```yaml
+services:
+  jobs-app:
+    volumes:
+      # Create empty directories
+      - type: bind
+        source: ./cache
+        target: /app/cache
+        is_directory: true
+
+      - type: bind
+        source: ./logs
+        target: /app/logs
+        is_directory: true
+
+  mysql:
+    volumes:
+      # Persistent database storage
+      - mysql_data:/var/lib/mysql
+```
+
+#### 4. Health Checks and Service Management
+
+```yaml
+services:
+  jobs-app:
+    # Exclude from health checks if needed
+    exclude_from_hc: false
+
+    # Labels for Coolify management
+    labels:
+      - coolify.managed=true
+      - traefik.enable=true
+      - "traefik.http.routers.jobs-app.rule=Host(`${SERVICE_FQDN_JOBS_APP:-localhost}`)"
+      - traefik.http.routers.jobs-app.entryPoints=http
+```
+
+#### 5. Database Configuration for Coolify
+
+Update your `config/settings.json` to use Coolify environment variables:
+
+```json
+{
+  "database": {
+    "mysql": {
+      "host": "mysql",
+      "user": "${DB_USER:-jobs}",
+      "password": "${DB_PASSWORD:-jobdb}",
+      "database": "jobs",
+      "port": 3306
+    }
+  }
+}
+```
+
+### Complete Coolify docker-compose.yml
+
+Here's a complete `docker-compose.yml` optimized for Coolify:
+
+```yaml
+version: "3.8"
+
+services:
+  jobs-app:
+    build: .
+    ports:
+      - "8000:8000"
+    environment:
+      # Required environment variables
+      - FLASK_SECRET=${FLASK_SECRET:?}
+      - FLASK_ENV=${FLASK_ENV:?production}
+
+      # Coolify magic variables
+      - SERVICE_FQDN_JOBS_APP
+      - ADMIN_PASSWORD=${SERVICE_PASSWORD_ADMIN:?M11ffpgm.}
+      - DB_USER=${SERVICE_USER_DB:?jobs}
+      - DB_PASSWORD=${SERVICE_PASSWORD_DB:?jobdb}
+
+      # Optional configuration
+      - GUNICORN_WORKERS=${GUNICORN_WORKERS:-4}
+    volumes:
+      - type: bind
+        source: ./cache
+        target: /app/cache
+        is_directory: true
+      - type: bind
+        source: ./logs
+        target: /app/logs
+        is_directory: true
+    depends_on:
+      - mysql
+    labels:
+      - coolify.managed=true
+      - traefik.enable=true
+      - "traefik.http.routers.jobs-app.rule=Host(`${SERVICE_FQDN_JOBS_APP:-localhost}`)"
+      - traefik.http.routers.jobs-app.entryPoints=http
+    networks:
+      - jobs-network
+    restart: unless-stopped
+
+  mysql:
+    image: mysql:8.0
+    environment:
+      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD:?rootpassword}
+      - MYSQL_DATABASE=jobs
+      - MYSQL_USER=${DB_USER:-jobs}
+      - MYSQL_PASSWORD=${DB_PASSWORD:-jobdb}
+    ports:
+      - "3306:3306"
+    volumes:
+      - mysql_data:/var/lib/mysql
+      - ./mysql-init:/docker-entrypoint-initdb.d
+    networks:
+      - jobs-network
+
+volumes:
+  mysql_data:
+
+networks:
+  jobs-network:
+    driver: bridge
+```
+
+### Coolify Deployment Steps
+
+1. **Connect Repository**: Link your Git repository to Coolify
+2. **Create Service Stack**: Choose "Docker Compose" as the build pack
+3. **Configure Environment Variables**: Set required variables in Coolify's UI:
+   - `FLASK_SECRET`: Generate a secure random string
+   - `FLASK_ENV`: Set to "production"
+   - `MYSQL_ROOT_PASSWORD`: Set a secure password
+4. **Deploy**: Coolify will automatically build and deploy your application
+5. **Access**: Use the generated FQDN to access your application
+
+### Coolify Benefits
+
+- **Automatic SSL**: HTTPS certificates are automatically managed
+- **Environment Management**: Easy variable management through UI
+- **Monitoring**: Built-in logging and health monitoring
+- **Scaling**: Easy horizontal scaling
+- **Backups**: Automated backup capabilities
+- **Security**: Isolated networks and secure defaults
+
+### Troubleshooting Coolify Deployments
+
+1. **Environment Variables**: Check that all required variables are set in Coolify's UI
+2. **Build Logs**: Review build logs for any compilation errors
+3. **Network Issues**: Ensure services can communicate within the stack
+4. **Storage Permissions**: Verify volume permissions are correct
+5. **FQDN Configuration**: Check that the generated FQDN is accessible
