FunctionGraph Function Creation Skill

Overview

• Quickly create cloud functions without manual console login
• Batch creation of multiple functions
• Foundation component for workflow deployment
• CI/CD integration for function deployment

1. "Create a Python function named my_handler"
2. "Deploy this code to FunctionGraph"
3. "Batch create 10 functions from template"

Prerequisites

1. Python Environment

• Python 3.9+
• Verify:

  python --version

2. SDK Installation

pip install huaweicloudsdkfunctiongraph

3. Authentication Configuration

• Valid Huawei Cloud credentials (AK/SK mode)
• Configure via environment variables:

export HUAWEI_AK="your-access-key"
export HUAWEI_SK="your-secret-key"
export HUAWEI_REGION="cn-north-4"
export HUAWEI_PROJECT_ID="your-project-id"

• NEVER expose AK/SK values in code or logs
• NEVER let users input AK/SK directly in conversation
• ALWAYS use environment variables for credentials
• Recommend using IAM user instead of main account

4. IAM Permission Requirements

• functiongraph:function:create

  - Create function

• functiongraph:function:get

  - Query function details

• functiongraph:function:list

  - List functions

Usage

Command

cd scripts
python create_function.py   --name <function_name>   --runtime <runtime>   --han
dler <handler>   --code <code_content>   --memory <memory_size>   --timeout <timeout>

Parameter Confirmation

function_name

runtime

code_content

handler

memory_size

timeout

description

Runtime Options

def handler(event, context):

exports.handler = (event, context) => {}

Verification Method

Quick Verification

## Verify function exists using SDK

from huaweicloudsdkfunctiongraph.v2.functiongraph_client import FunctionGraphClient
from huaweicloudsdkfunctiongraph.v2.model import ListFunctionsRequest

# List functions to verify creation
client = FunctionGraphClient.new_builder().build()
request = ListFunctionsRequest()
response = client.list_functions(request)
print(f"Total functions: {len(response.functions)}")

Output Format

• function_urn

  : Unique resource identifier of the created function

• function_name

  : Name of the created function

• runtime

  : Runtime environment

• memory_size

  : Allocated memory in MB

• timeout

  : Function timeout in seconds

• handler

  : Function entry point

• description

  : Function description (if provided)

{
  "function_urn": "urn:fss:cn-north-4:project_id:function:default:my_function",
  "function_name": "my_function",
  "runtime": "Python3.9",
  "memory_size": 128,
  "timeout": 3,
  "handler": "index.handler",
  "description": "Test function created by skill"
}

Best Practices

1. Test before production: Always test in a development environment first
2. Monitor resources: Set up monitoring for function invocations and errors
3. Use environment variables: Store sensitive data in environment variables
4. Implement error handling: Add proper error handling in function code
5. Set appropriate timeouts: Configure timeout based on function logic
