# Coolify Deployment Architecture

## Deployment Philosophy

Coolify orchestrates **Docker-based deployments** across multiple servers with automated configuration generation, zero-downtime deployments, and comprehensive monitoring.

## Core Deployment Components

### Deployment Models
- **[Application.php](mdc:app/Models/Application.php)** - Main application entity with deployment configurations
- **[ApplicationDeploymentQueue.php](mdc:app/Models/ApplicationDeploymentQueue.php)** - Deployment job orchestration
- **[Service.php](mdc:app/Models/Service.php)** - Multi-container service definitions
- **[Server.php](mdc:app/Models/Server.php)** - Target deployment infrastructure

### Infrastructure Management
- **[PrivateKey.php](mdc:app/Models/PrivateKey.php)** - SSH key management for secure server access
- **[StandaloneDocker.php](mdc:app/Models/StandaloneDocker.php)** - Single container deployments
- **[SwarmDocker.php](mdc:app/Models/SwarmDocker.php)** - Docker Swarm orchestration

## Deployment Workflow

### 1. Source Code Integration
```
Git Repository → Webhook → Coolify → Build & Deploy
```

#### Source Control Models
- **[GithubApp.php](mdc:app/Models/GithubApp.php)** - GitHub integration and webhooks
- **[GitlabApp.php](mdc:app/Models/GitlabApp.php)** - GitLab CI/CD integration

#### Deployment Triggers
- **Git push** to configured branches
- **Manual deployment** via UI
- **Scheduled deployments** via cron
- **API-triggered** deployments

### 2. Build Process
```
Source Code → Docker Build → Image Registry → Deployment
```

#### Build Configurations
- **Dockerfile detection** and custom Dockerfile support
- **Buildpack integration** for framework detection
- **Multi-stage builds** for optimization
- **Cache layer** management for faster builds

### 3. Deployment Orchestration
```
Queue Job → Configuration Generation → Container Deployment → Health Checks
```

## Deployment Actions

### Location: [app/Actions/](mdc:app/Actions)

#### Application Deployment Actions

## Configuration Generation

### Dynamic Configuration
- **[ConfigurationGenerator.php](mdc:app/Services/ConfigurationGenerator.php)** - Generates deployment configurations
- **[ConfigurationRepository.php](mdc:app/Services/ConfigurationRepository.php)** - Configuration management

### Generated Configurations
#### Docker Compose Files
```yaml
# Generated docker-compose.yml structure
version: '3.8'
services:
  app:
    image: ${APP_IMAGE}
    environment:
      - ${ENV_VARIABLES}
    labels:
      - traefik.enable=true
      - traefik.http.routers.app.rule=Host(`${FQDN}`)
    volumes:
      - ${VOLUME_MAPPINGS}
    networks:
      - coolify
```

#### Nginx Configurations
- **Reverse proxy** setup
- **SSL termination** with automatic certificates
- **Load balancing** for multiple instances
- **Custom headers** and routing rules

## Container Orchestration

### Docker Integration
- **[DockerImageParser.php](mdc:app/Services/DockerImageParser.php)** - Parse and validate Docker images

- **Resource allocation** and limits
- **Network isolation** and communication

### Volume Management
- **[LocalFileVolume.php](mdc:app/Models/LocalFileVolume.php)** - Persistent file storage

- **Backup integration** for volume data

### Network Configuration
- **Custom Docker networks** for isolation
- **Service discovery** between containers
- **Port mapping** and exposure
- **SSL/TLS termination**

## Environment Management

### Environment Isolation
- **[Environment.php](mdc:app/Models/Environment.php)** - Development, staging, production environments
- **[EnvironmentVariable.php](mdc:app/Models/EnvironmentVariable.php)** - Application-specific variables
- **[SharedEnvironmentVariable.php](mdc:app/Models/SharedEnvironmentVariable.php)** - Cross-application variables

### Configuration Hierarchy
```
Instance Settings → Server Settings → Project Settings → Application Settings
```

## Preview Environments

### Git-Based Previews
- **[ApplicationPreview.php](mdc:app/Models/ApplicationPreview.php)** - Preview environment management
- **Automatic PR/MR previews** for feature branches
- **Isolated environments** for testing
- **Automatic cleanup** after merge/close

### Preview Workflow
```
Feature Branch → Auto-Deploy → Preview URL → Review → Cleanup
```

## SSL & Security

### Certificate Management
- **[SslCertificate.php](mdc:app/Models/SslCertificate.php)** - SSL certificate automation
- **Let's Encrypt** integration for free certificates
- **Custom certificate** upload support
- **Automatic renewal** and monitoring

### Security Patterns
- **Private Docker networks** for container isolation
- **SSH key-based** server authentication
- **Environment variable** encryption
