🎯 What is DockAI?

DockAI is an agentic AI framework that analyzes your codebase and generates optimized, production-ready Dockerfiles. Unlike template-based tools, DockAI uses first-principles reasoning to understand your application and create Dockerfiles from scratch—handling everything from standard stacks to legacy systems.

# Using pip
pip install dockai-cli

# Or using uv (faster)
uv pip install dockai-cli

dockai build /path/to/project

That's it. DockAI handles the rest.

✨ Features

🧠 First-Principles AI No templates. Analyzes file structures, dependencies, and code patterns to deduce the optimal containerization strategy.	🔄 Self-Correcting Workflow Builds and tests Dockerfiles in a sandbox. If something fails, AI reflects, learns, and retries with a new approach.
🛡️ Security-First Built-in Trivy CVE scanning and Hadolint linting. Enforces non-root users, minimal base images, and hardened configs.	🤖 8 Specialized Agents Each agent handles a specific task: analysis, planning, generation, review, and more. All fully customizable.
⚡ Multi-Provider LLMs Supports OpenAI, Azure, Gemini, Anthropic, and Ollama. Mix and match providers per agent (e.g., OpenAI for analysis, Ollama for generation).	🔧 Fully Customizable Override prompts, instructions, and model selection per agent. Use .dockai files for repo-specific configs.
📦 Smart Registry Integration Automatically validates base images against Docker Hub, GCR, Quay, and GHCR. Prioritizes small, secure variants like alpine and slim.	📊 Full Observability Built-in OpenTelemetry tracing and LangSmith support for distributed observability and LLM debugging. Export traces to console, OTLP backends, or LangSmith.

🚀 Three Ways to Use DockAI

DockAI is designed to fit into any workflow, whether you are a developer, a DevOps engineer, or an AI user.

1. The CLI (For Developers)

Perfect for running locally on your machine.

# Install (choose one)
pip install dockai-cli    # Using pip
uv pip install dockai-cli # Using uv (faster)

# Run
dockai build .

2. GitHub Actions (For CI/CD)

Automate Dockerfile generation in your pipelines.

steps:
  - uses: actions/checkout@v3
  - uses: itzzjb/dockai@v3
    with:
      openai_api_key: ${{ secrets.OPENAI_API_KEY }}

3. MCP Server (For AI Agents)

Use DockAI directly inside Claude Desktop, Cursor, or any MCP-compliant tool.

1. Install dockai-cli.
2. Configure your MCP client:

{
  "mcpServers": {
    "dockai": {
      "command": "python",
      "args": ["-m", "dockai.core.mcp_server"]
    }
  }
}

3. Ask your AI: "Analyze this project and generate a Dockerfile for it."

Configuration

Create a .env file:

# Required: Choose your LLM provider and add the API key
OPENAI_API_KEY=sk-your-api-key

# Optional: Use a different provider (openai, azure, gemini, anthropic, ollama)
# DOCKAI_LLM_PROVIDER=openai

Usage

# Generate Dockerfile for your project
dockai build /path/to/project

# With verbose output
dockai build /path/to/project --verbose

        with:
          openai_api_key: ${{ secrets.OPENAI_API_KEY }}

💡 Tip: By default, the Dockerfile is generated at runtime and not committed. If you want to save it to your repository, see the Committing Generated Dockerfile guide.

Multi-Provider Example

- uses: itzzjb/dockai@v3
  with:
    llm_provider: gemini
    google_api_key: ${{ secrets.GOOGLE_API_KEY }}
    max_retries: 5
    strict_security: true

Mixed Provider Example

Use Ollama locally for most tasks, but OpenAI for complex analysis:

# .env
DOCKAI_LLM_PROVIDER=ollama
DOCKAI_MODEL_ANALYZER=openai/gpt-4o-mini

See GitHub Actions Guide for all options.
