Updating function configuration on Serverless Framework CLI

1. If you want to modify the function configuration, you can directly modify the serverless.yml configuration file under the function root directory as shown below:

   name: scfdemo # Name of the instance created by this component, which is required
   inputs:
   name: scfFunctionName
   src: ./src
   runtime: Nodejs10.15 # Runtime environment of function. Valid values: Python2.7, Python3.6, Nodejs6.10, Nodejs8.9,Nodejs12.16, PHP5, PHP7, Golang1, Java8.
   region: ap-guangzhou
   handler: index.main_handler
   events:
    - apigw:
        name: serverless_api
        parameters:
          protocols:
            - http
            - https
          serviceName:
          description: The service of Serverless Framework
          environment: release
          endpoints:
            - path: /index
              method: GET

2. After the modification is completed, run sls deploy on Serverless Framework CLI to deploy the function.

Updating Function Code

Updating function code in console

1. Log in to the SCF Console and click Function Service on the left sidebar.
2. Select the region of the function to be updated at the top of the page and click the target function in the list to enter the function details page.
3. Switch to the function code page and edit the function code in the following way:
   • For scripting languages: you can directly use the function code editor.
   • For non-scripting languages: you can submit the function code by uploading a zip package or through COS and then edit it.
