Clawtainer

Browser-accessible Linux desktop with AI coding tools pre-installed: OpenClaw, VS Code, Cursor, Antigravity, and Anthropic Python SDK.

Quick Start

git clone git@git.nixc.us:colin/clawtainer.git
cd clawtainer
docker compose up -d

Access from any device on your LAN:

• Desktop (VNC): http://YOUR_IP:6901 (no password)
• OpenClaw Gateway: http://YOUR_IP:18789

First-time setup: OpenClaw requires API keys from AI providers (Anthropic, OpenAI, Google, etc.). See OpenClaw Setup below.

Run (Docker Compose)

docker compose up -d

• Desktop: http://localhost:6901 (no password required)
• OpenClaw Control UI: http://localhost:18789 (token: clawtainer)

The nginx proxy strips TLS from the VNC connection for easy browser access.

Set OpenClaw token: OPENCLAW_GATEWAY_TOKEN=mytoken docker compose up -d

Build (standalone)

docker build -t clawtainer:local .

Kasm Workspaces Setup

1. Register a new Workspace in Kasm Admin
2. Set Docker Image to clawtainer:local (or your tagged name)
3. Add port 18789 to the workspace's port configuration
4. Save and launch a session

OpenClaw Setup

OpenClaw is an open-source AI agent orchestration platform that connects to AI provider APIs (Anthropic, OpenAI, Google, etc.). The Gateway auto-starts on port 18789, but you need to configure it with your own API keys.

Setup Options:

1. Interactive Wizard (easiest):

   openclaw onboard
   

   Walks you through model selection and API key entry.

2. Manual Configuration: Edit ~/.openclaw/openclaw.json or use environment variables:

   export ANTHROPIC_API_KEY="sk-ant-..."
   export OPENAI_API_KEY="sk-..."
   export GOOGLE_API_KEY="AIza..."
   

3. Via Gateway UI:

   • Open http://localhost:18789 in browser
   • Navigate to Settings
   • Add your API keys for desired providers

Get API Keys:

• Anthropic (Claude): https://console.anthropic.com/
• OpenAI (GPT): https://platform.openai.com/api-keys
• Google (Gemini): https://makersuite.google.com/app/apikey
• OpenRouter: https://openrouter.ai/keys

Note: OpenClaw itself is free and open-source. You only pay for API usage from your chosen AI providers.

Usage

After startup, open the desktop at port 6901. Desktop shortcuts are available:

• OpenClaw Control - Opens the gateway UI at http://localhost:18789
• VS Code - Launches Visual Studio Code
• Cursor - AI-powered code editor
• Antigravity - Google's AI IDE

Access the Control UI to configure API keys, set up messaging channels (Telegram, WhatsApp, etc.), and manage AI agents.
