Cert Manager

Cert Manager Skill

Description

This skill provides automated SSL certificate generation and management capabilities using DNS validation (Let's Encrypt). It offers flexibility through multiple usage routes, allowing you to choose the best method for your specific development or deployment scenario.

Usage Routes

Choose the most appropriate route based on your scenario:

Detailed Instructions

Route 1: Code Import

Import and use the SSLCertUpdater class directly in Python code.

Configuration:

• Configure DNS Provider AccessKey/SecretKey (via env vars or args).

Example:

import asyncio
from chattool.tools.cert.cert_updater import SSLCertUpdater
from chattool.utils import setup_logger

async def main():
    updater = SSLCertUpdater(
        domains=["example.com", "*.example.com"],
        email="admin@example.com",
        dns_type="aliyun",
        cert_dir="./certs",
        access_key_id="...",      # Optional, defaults to env var
        access_key_secret="..."   # Optional, defaults to env var
    )
    success = await updater.run_once()
    if success:
        print("Certificate generated successfully!")

if __name__ == "__main__":
    asyncio.run(main())

Route 2: CLI

Use the chattool command-line interface to request certificates directly.

Configuration:

• Set env vars ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET (for Aliyun).

Example:

# Generate certificate
chattool dns cert-update \
    -d example.com -d "*.example.com" \
    -e admin@example.com \
    --provider aliyun \
    --cert-dir ./my-certs

Route 3: Server-Client

Start an HTTP server to handle certificate requests and call it remotely via the client tool. Supports multi-tenant isolation (Token-based).

Step 1: Start Server

# Start on server, set auth token
chattool serve cert --token "my-secret-token" --provider aliyun

Step 2: Client Call

# Apply for certificate (Client side)
chattool client cert apply \
    -d example.com -d "*.example.com" \
    --token "my-secret-token" \
    --server http://<server-ip>:8000

# List certificates
chattool client cert list --token "my-secret-token" --server http://<server-ip>:8000

# Download certificate
chattool client cert download example.com --token "my-secret-token" --server http://<server-ip>:8000

Route 4: MCP Protocol

Call tools via MCP protocol if the ChatTool MCP Server is running.

Tool Name: dns_cert_update

Arguments:

• domains: List[str] (e.g., ["example.com"])
• email: str
• provider: str ("aliyun" or "tencent")

Example (JSON-RPC):

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "dns_cert_update",
    "arguments": {
      "domains": ["example.com"],
      "email": "admin@example.com",
      "provider": "aliyun"
    }
  },
  "id": 1
}
