Function Compute:Manage function resources by using Serverless Devs

Initialize the project

sudo s init devsapp/start-fc-http-nodejs14

This example deploys an HTTP function in Node.js 14. Replace http with a different trigger type such as event to change the function type. Replace nodejs14 with another runtime identifier to change the runtime.

Sample output:

    Welcome to the Aliyun FC start application
     This application requires to open these services:
         FC : https://fc.console.alibabacloud.com/

     * The project is initialized. You can go to the project directory and run the s deploy command to deploy the project.

 Thanks for using Serverless-Devs
 You could [cd /test/start-fc-http-nodejs14] and enjoy your serverless journey!
 If you need help for this example, you can use [s -h] after you enter folder.

 Do you want to deploy the project immediately? No

After initialization, the project directory contains these files:

Enter the project directory

cd start-fc-http-nodejs14

Build the project (optional)

Run s build to compile and package the project locally:

sudo s build

This generates a .s directory in the project root that stores build artifacts for debugging and deployment.

Debug locally (optional)

After building, test the function on your machine before deploying.

HTTP functions:

sudo s local start

Sample output:

[2021-12-16 07:17:05] [INFO] [FC-LOCAL-INVOKE] - Using trigger for start: name: httpTrigger
type: http
config:
  authType: anonymous
  methods:
    - GET

[2021-12-16 07:17:05] [INFO] [FC-LOCAL-INVOKE] - HttpTrigger httpTrigger of hello-world-service/http-trigger-nodejs14 was registered
        url: http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/
        methods: GET
        authType: anonymous

Tips: You can also use these commands to run or debug custom domain resources:

Start with customDomain:
* s local start auto

Debug with customDomain:
* s local start -d 3000 auto


Tips for next step
======================
* Deploy Resources: s deploy
helloworld:
  status: succeed
function compute app listening on port 7013!

Trigger the HTTP function with cURL or a browser:

curl http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Or open the following URL in a browser:

http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Event functions:

sudo s local invoke

The result is returned directly after the command runs.

Deploy to Function Compute

sudo s deploy -y

Sample output:

Checking Service, Function, Triggers (0.82s)
 Creating Service, Function, Triggers (0.6s)
 Creating custom domain (0.31s)

Tips for next step
======================
* Display information of the deployed resource: s info
* Display metrics: s metrics
* Display logs: s logs
* Invoke remote function: s invoke
* Remove Service: s remove service
* Remove Function: s remove function
* Remove Trigger: s remove trigger
* Remove CustomDomain: s remove domain

helloworld:
  region:   cn-hangzhou
  service:

  triggers:
    -
      type: http
      name: httpTrigger

Invoke the function remotely (optional)

After deployment, invoke the function in the cloud to verify it works:

sudo s invoke -e '{"body": "","method":"GET","headers":{"header_1":"v1"},"queries":{"key":"value"},"path":"/"}'

Sample output:

End of method: invoke

You can also trigger an HTTP function with cURL:

curl https://188077086902****.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Remove resources (optional)

When you no longer need the deployed resources, delete them:

sudo s remove service

Sample output:

Need to delete the resource in the cn-hangzhou area, the operation service is hello-world-service:
 ......
 Delete trigger hello-world-service/http-trigger-nodejs14/httpTrigger success.
 Delete function hello-world-service/http-trigger-nodejs14 success.
 Delete service hello-world-service success.

End of method: remove

This command deletes triggers, functions, and the service in sequence, and cleans up related NAS service resources.
