Quickly Deploying a Function Template
Last updated: 2024-12-02 10:48:10
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.
Note
If your account is a Tencent Cloud sub-account, first get the authorization from the root account as instructed in Account and Permission Configuration.
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?

Click Deploy Now to quickly deploy the initialized project to the SCF console:

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 herescf 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.
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 portHTTPS_PROXY=http://127.0.0.1:12345 # Replace "12345" with your proxy port
