      Overview

      This document describes how to use Serverless Cloud Framework to quickly create, configure, and deploy an Serverless Cloud Function (SCF) application on Tencent Cloud.

      Prerequisites

      You have installed Serverless Cloud Framework 1.67.2 or later. For more information, see Installing Serverless Cloud Framework.
      You have signed up for a Tencent Cloud account as instructed in Signing Up.

      Directions

      Quick deployment

      In an empty folder directory, run the following command:
      serverless-cloud-framework
      Next, initialize the project as prompted. Select the scf-starter template for the application and select the runtime you want to use (Node.js is used as an example here):
      serverless-cloud-framework: No Serverless project is detected. Do you want to create a project? Yes
      serverless-cloud-framework: Select the Serverless application you want to create: scf-starter - quickly deploys an SCF function
      
        react-starter - quickly deploys a React.js application 
        restful-api - quickly deploys a RESTful API to use Python + API Gateway 
      ❯ scf-starter - quickly deploys an SCF function 
        vue-starter - quickly deploys a basic Vue.js application 
        website-starter - quickly deploys a static website 
        eggjs-starter - quickly deploys a basic Egg.js application 
        express-starter - quickly deploys a basic Express.js application 
      
      serverless-cloud-framework: Select the runtime of the application: scf-nodejs - quickly deploys an SCF function in Node.js
      
        scf-golang - quickly deploys an SCF function in Go 
      ❯ scf-nodejs - quickly deploys an SCF function in Node.js 
        scf-php - quickly deploys an SCF function in PHP 
        scf-python - quickly deploys an SCF function in Python

      184s »scf-nodejs» Execution succeeded.
      After deployment, complete the remote invocation of the function by running the following command:
      scf invoke --inputs function=helloworld
      Note
      scf is short for serverless-cloud-framework.

      Viewing the Deployment Information

      To view the application deployment statuses and resources again, go to the directory that is successfully deployed and run the following command:
      cd demo # Enter the project directory. Please change to your actual project's directory name here
      scf info

      Viewing the directory structure

      In the directory of the initialized project, you can see the most basic structure of a serverless function project:
      .
      ├── serverless.yml  # Configuration file
      ├—— index.js    # Entry function
      └── .env # Environment variable file
      The serverless.yml configuration file implements the quick configuration of the basic function information. All the configuration items supported by the SCF console can be configured in the .yml file. For more information, see SCF Configuration Information.
      index.js is the entry function of the project, which is the helloworld template here.
      The .env file stores user login authentication information. You can also configure other environment variables in it.

      Redeployment

      In the local project directory, you can modify the function template and configuration file and then redeploy the project by running the following command:
      scf deploy
      Note
      To view the detailed information during removal, you can add the --debug parameter.

      Continuous development

      After the deployment is completed, Serverless Cloud Framework allows you to run different commands to implement capabilities such as continuous development and grayscale release for the project. You can also use this component in conjunction with other components to manage the deployment of multi-component applications.
      For more information, see Application Management and List of Supported Commands.

      FAQs

      Question 1: What should I do if the wizard does not pop up by default after I enter serverless-cloud-framework .
      Solution: Add the SERVERLESS_PLATFORM_VENDOR=tencent configuration to the .env file.
      Question 2: What should I do if the deployment is very slow in an overseas network after I enter sls deploy ?
      Solution: Add the GLOBAL_ACCELERATOR_NA=true configuration to the .env file to accelerate the overseas network.
      Question 3: What should I do if a network error occurs during deployment after I enter scf deploy ?
      Solution: Add the following proxy configurations to the .env file.
      HTTP_PROXY=http://127.0.0.1:12345 # Replace "12345" with your proxy port
      HTTPS_PROXY=http://127.0.0.1:12345 # Replace "12345" with your proxy port
