Architecture Overview

Trailer.dev is built with a modern, modular architecture that separates concerns and enables flexible deployment options. This document provides an overview of the system's architecture.

System Components

Core Components

1. Server

   • Handles user authentication and authorization
   • Manages workspace access control and permissions
   • Validates workspace URL access based on authorized users
   • Coordinates workspace deployments across multiple agents
   • Manages workspace lifecycle and resource allocation
   • Enforces workspace-level security policies
   • Handles agent discovery and workspace distribution

2. Agent

   • Manages container resources (Docker/Kubernetes)
   • Handles environment creation and management
   • Monitors resource usage and health
   • Executes commands in containers

3. Client

   • Web-based interface for user interaction
   • Real-time updates and monitoring
   • Resource management interface
   • Workspace configuration tools

Key Features

1. Multi-Mode Operation

   • Server mode: Centralized management
   • Agent mode: Resource management
   • Standalone mode: Combined functionality

2. Resource Management

   • Container orchestration
   • GPU allocation
   • Network configuration
   • Volume management

3. Security

   • Role-based access control
   • Secure communication
   • Resource isolation

Deployment Modes

Server Mode

The server component handles:

• User authentication
• Workspace management
• Agent coordination
• Workspace access control

Agent Mode

The agent component manages:

• Container resources
• Environment setup
• Resource monitoring
• Command execution

Standalone Mode

Combines server and agent functionality in a single deployment:

• Simplified setup
• Single process
• Local resource management
• Development features

Data Flow

1. Client requests workspace creation
2. Server validates request and selects appropriate agent
3. Server coordinates workspace deployment with agent
4. Agent creates and manages resources
5. Status updates flow back to client through server

Security Architecture

Authentication

• JWT-based authentication
• Role-based access control
• Session management
• Workspace-specific access tokens

Authorization

• Workspace-level access control

Resource Management

Container Resources

• Docker container management
• Kubernetes pod management
• Resource allocation
• Health monitoring

GPU Support

• NVIDIA GPU detection
• Memory allocation
• Multi-GPU support
• Resource monitoring

Storage Management

• Volume mounting
