@vibe-kit/dagger

Local sandbox provider for Vibekit using Dagger.

Overview

The @vibe-kit/dagger package enables Vibekit to run AI coding agents in isolated, containerized environments on your local machine. This provides an alternative to cloud-based sandboxes, offering faster iteration, offline development, and cost savings.

System Requirements

Required Dependencies

• Docker: Container runtime for isolation
• Dagger: Container orchestration engine

Supported Platforms

• macOS (recommended)
• Linux
• Windows (WSL2)

Minimum System Resources

• 8GB RAM (16GB recommended for multiple environments)
• 10GB free disk space
• Modern CPU with virtualization support

Installation

The local provider is automatically available when you install Vibekit. System dependencies are installed automatically when you first use the local provider:

# Initialize with local provider
vibekit init --provider dagger

# Or add to existing project
vibekit dagger setup

Manual Dependency Installation

If automatic installation fails, you can install dependencies manually:

# Install Docker (platform-specific)
# See: https://docs.docker.com/get-docker/

# Install Dagger
curl -fsSL https://dagger.io/install.sh | bash

# Verify installation
dagger version

Usage

Basic API Usage

import { createLocalProvider } from '@vibe-kit/dagger';

// Create a local provider
const provider = createLocalProvider();

// Create a sandbox instance
const sandbox = await provider.create(
  { NODE_ENV: 'development' }, // environment variables
  'claude',                    // agent type
  '/vibe0'                     // working directory
);

// Execute commands
const result = await sandbox.commands.run('npm install');
console.log(result.stdout);

// Clean up
await sandbox.kill();

Configuration

import { createLocalProvider, LocalDaggerConfig } from '@vibe-kit/dagger';

const config: LocalDaggerConfig = {
  // Configuration options for the local provider
};

const provider = createLocalProvider(config);

Architecture

The local provider consists of several key components:

• Dagger Integration: Low-level container orchestration
• Environment Manager: Lifecycle and state management
• Container Persistence: Workspace state across commands
• Agent Configuration: Support for multiple agent types
• Resource Management: Docker container orchestration

Agent Support

The local provider supports all Vibekit agent types:

• Claude: Uses assets/dockerfiles/Dockerfile.claude
• Codex: Uses assets/dockerfiles/Dockerfile.codex
• OpenCode: Uses assets/dockerfiles/Dockerfile.opencode
• Gemini: Uses assets/dockerfiles/Dockerfile.gemini

Each agent type can have its own optimized container image for better performance.

Security Considerations

Local sandboxes run in Docker containers with the following isolation:

• File System: Containers cannot access host files outside mounted volumes
• Network: Containers run in isolated Docker networks
• Process: Complete process isolation from host system
• Resources: Configurable CPU and memory limits

Interface Compatibility

This package implements the same SandboxProvider interface as other Vibekit providers:

interface SandboxProvider {
  create(envs?, agentType?, workingDirectory?): Promise<SandboxInstance>;
  resume(sandboxId: string): Promise<SandboxInstance>;
}

interface SandboxInstance {
  sandboxId: string;
  commands: SandboxCommands;
  kill(): Promise<void>;
  pause(): Promise<void>;
  getHost(port: number): Promise<string>;
}

This ensures you can swap between local and cloud providers seamlessly.

Troubleshooting

Common Issues

Docker not running:

# Check Docker status
docker ps

# Start Docker Desktop (macOS/Windows)
# Or start Docker daemon (Linux)

Dagger not found:

# Reinstall Dagger
curl -fsSL https://dagger.io/install.sh | bash

# Check PATH
which dagger

Permission errors:

# Add user to docker group (Linux)
sudo usermod -aG docker $USER
# Then log out and back in

Debug Mode

Enable verbose logging for troubleshooting:

export VIBEKIT_LOG_LEVEL=debug
# Your Vibekit commands here
