After deployment, complete the remote invocation of the function by running the following command:
sls invoke --inputs function=helloworld
slsis short for the
If you want to check the deployment status and resources of the application again, you can go to the folder where the project is successfully deployed and run the following command to view the corresponding information:
cd demo # Enter the project directory. Please change to your actual project's directory name here sls info
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
serverless.ymlconfiguration file implements the quick configuration of the basic function information. All the configuration items supported by the SCF console can be configured in the
.ymlfile (for more information, please see SCF Configuration Information).
index.jsis the entry function of the project, which is the
.envfile stores user login authentication information. You can also configure other environment variables in it.
In the local project directory, you can modify the function template and configuration file and then redeploy the project by running the following command:
If you want to view the details during the removal process, you can add the
After the deployment is completed, Serverless Framework supports running different commands to help you implement continuous development, deployment, 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.
Problem 1: the wizard does not pop up by default when
serverless is entered.
Solution: add the
SERVERLESS_PLATFORM_VENDOR=tencent configuration item to the
Problem 2: after
sls deploy is entered in a network environment outside the Chinese mainland, the deployment is very slow.
Solution: add the
GLOBAL_ACCELERATOR_NA=true configuration item to the
.env file to enable acceleration outside the Chinese mainland.
Problem 3: after
sls deploy is entered, the deployment reports a network error.
Solution: add the following proxy configuration to the
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
