📖 Background of Claude Code Dockerization¶

As of 2025, there is no official Claude Code Docker image from Anthropic. However, with official DevContainer support and numerous community implementations, Docker-based Claude Code environments are rapidly gaining adoption.

Why Docker Containerization is Important¶

Claude Code is a powerful AI development assistant tool, but it had the following challenges:

Permission Management Complexity: Permission confirmation required for every operation
Environment Consistency: Different development environments across teams
Security Risks: Direct access to host system
Windows Compatibility: Constraints due to WSL dependency

Docker containerization solves these challenges.

🏗️ Available Docker Implementation Options¶

1. Official DevContainer (Recommended)¶

Official DevContainer implementation from Anthropic.

# .devcontainer/devcontainer.json
{
  "name": "Claude Code DevContainer",
  "dockerFile": "Dockerfile",
  "features": {
    "ghcr.io/anthropics/devcontainer-features/claude-code:latest": {}
  },
  "customizations": {
    "vscode": {
      "extensions": [
        "ms-vscode.vscode-typescript-next"
      ]
    }
  }
}

Key Features: - Multi-layered security approach - Automated firewall configuration - VS Code integration - Team development support

2. Community Implementations (Options)¶

ClaudeBox by RchGrav¶

# Provides complete development environment
docker pull ghcr.io/rchgrav/claudebox:latest
docker run -it -v $(pwd):/workspace claudebox:latest

Zeeno-atl Version (Lightweight)¶

# Auto-installs latest Claude Code CLI
docker pull ghcr.io/zeeno-atl/claude-code:latest
docker run -it -v $(pwd):/project ghcr.io/zeeno-atl/claude-code:latest

DeepWorks Version (Windows Specialized)¶

# Windows WSL-free version
docker pull deepworks/claude-code:latest
docker run -it -v .:/home/coder/project deepworks/claude-code:latest

🔒 Security Features and Isolation¶

Network Restrictions¶

Docker containerization allows restricting Claude Code's network access:

# Firewall configuration example
FROM ubuntu:22.04

# Install necessary packages
RUN apt-get update && apt-get install -y \
    iptables \
    curl \
    npm \
    git

# Set up firewall rules
COPY init-firewall.sh /usr/local/bin/
RUN chmod +x /usr/local/bin/init-firewall.sh

# Allow access only to approved domains:
# - npm registry
# - GitHub
# - Anthropic API
# Block all others

Permission Isolation¶

# Safe permission skip mode
docker run --rm -it \
  -v $(pwd):/workspace \
  --network restricted \
  claude-code:latest \
  claude --dangerously-skip-permissions "Analyze the project"

💡 Practical Usage Methods¶

1. Basic Project Work¶

# Mount project directory and execute
docker run -it --rm \
  -v $(pwd):/workspace \
  -w /workspace \
  ghcr.io/zeeno-atl/claude-code:latest \
  claude "Create basic React app structure"

2. CI/CD Pipeline Integration¶

# GitHub Actions example
name: Claude Code Review
on: [pull_request]

jobs:
  code-review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Run Claude Code Analysis
        run: |
          docker run --rm \
            -v ${{ github.workspace }}:/workspace \
            -e ANTHROPIC_API_KEY=${{ secrets.ANTHROPIC_API_KEY }} \
            ghcr.io/zeeno-atl/claude-code:latest \
            claude -p "Perform code review and report improvements"

3. Unified Environment for Team Development¶

# docker-compose.yml
version: '3.8'
services:
  claude-dev:
    image: ghcr.io/rchgrav/claudebox:latest
    volumes:
      - .:/workspace
      - claude-config:/home/claude/.config
    environment:
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
    networks:
      - claude-network

volumes:
  claude-config:

networks:
  claude-network:
    driver: bridge

4. Windows Environment Usage¶
