webdevcody af394183e6 feat: add Cursor CLI installation attempts documentation and enhance Docker setup
- Introduced a new markdown file summarizing various attempts to install the Cursor CLI in Docker, detailing approaches, results, and key learnings.
- Updated Dockerfile to ensure proper installation of Cursor CLI for the non-root user, including necessary PATH adjustments for interactive shells.
- Enhanced entrypoint script to manage OAuth tokens for both Claude and Cursor CLIs, ensuring correct permissions and directory setups.
- Added scripts for extracting OAuth tokens from macOS Keychain and Linux JSON files for seamless integration with Docker.
- Updated docker-compose files to support persistent storage for CLI configurations and authentication tokens.

These changes improve the development workflow and provide clear guidance on CLI installation and authentication processes.

Docker Isolation Guide

This guide covers running Automaker in a fully isolated Docker container. For background on why isolation matters, see the Security Disclaimer.

Quick Start

  1. Set your API key (create a .env file in the project root):

    # Linux/Mac
    echo "ANTHROPIC_API_KEY=your-api-key-here" > .env
    
    # Windows PowerShell
    Set-Content -Path .env -Value "ANTHROPIC_API_KEY=your-api-key-here" -Encoding UTF8
    
  2. Build and run:

    docker-compose up -d
    
  3. Access Automaker at http://localhost:3007

  4. Stop:

    docker-compose down
    

How Isolation Works

The default docker-compose.yml configuration:

  • Uses only Docker-managed volumes (no host filesystem access)
  • Server runs as a non-root user
  • Has no privileged access to your system

Projects created in the UI are stored inside the container at /projects and persist across restarts via Docker volumes.

Mounting a Specific Project

If you need to work on a host project, create docker-compose.project.yml:

services:
  server:
    volumes:
      - ./my-project:/projects/my-project:ro # :ro = read-only

Then run:

docker-compose -f docker-compose.yml -f docker-compose.project.yml up -d

Tip: Use :ro (read-only) when possible for extra safety.

CLI Authentication (macOS)

On macOS, OAuth tokens are stored in Keychain (Claude) and SQLite (Cursor). Use these scripts to extract and pass them to the container:

Claude CLI

# Extract and add to .env
echo "CLAUDE_OAUTH_CREDENTIALS=$(./scripts/get-claude-token.sh)" >> .env

Cursor CLI

# Extract and add to .env (extracts from macOS Keychain)
echo "CURSOR_AUTH_TOKEN=$(./scripts/get-cursor-token.sh)" >> .env

Note: The cursor-agent CLI stores its OAuth tokens separately from the Cursor IDE:

  • macOS: Tokens are stored in Keychain (service: cursor-access-token)
  • Linux: Tokens are stored in ~/.config/cursor/auth.json

Apply to container

# Restart with new credentials
docker-compose down && docker-compose up -d

Note: Tokens expire periodically. If you get authentication errors, re-run the extraction scripts.

CLI Authentication (Linux/Windows)

On Linux/Windows, cursor-agent stores credentials in files, so you can either:

Option 1: Extract tokens to environment variables (recommended)

# Linux: Extract tokens to .env
echo "CURSOR_AUTH_TOKEN=$(jq -r '.accessToken' ~/.config/cursor/auth.json)" >> .env

Option 2: Bind mount credential directories directly

# In docker-compose.override.yml
volumes:
  - ~/.claude:/home/automaker/.claude
  - ~/.config/cursor:/home/automaker/.config/cursor

Troubleshooting

Problem Solution
Container won't start Check .env has ANTHROPIC_API_KEY set. Run docker-compose logs for errors.
Can't access web UI Verify container is running with docker ps | grep automaker
Need a fresh start Run docker-compose down && docker volume rm automaker-data && docker-compose up -d --build
Cursor auth fails Re-extract token with ./scripts/get-cursor-token.sh - tokens expire periodically. Make sure you've run cursor-agent login on your host first.
