This plugin enables Aliyun Function Compute support within the Serverless Framework.
npm i -g serverless.You can install the following example from GitHub:
$ serverless install --url https://github.com/aliyun/serverless-function-compute-examples/tree/master/aliyun-nodejs
The structure of the project should look something like this:
├── index.js
├── node_modules
├── package.json
└── serverless.yml
Install serverless-aliyun-function-compute plugin to your service.
$ serverless plugin install --name serverless-aliyun-function-compute
serverless.yml:
service: serverless-aliyun-hello-world
provider:
name: aliyun
runtime: nodejs8
credentials: ~/.aliyun_credentials # path must be absolute
plugins:
- serverless-aliyun-function-compute
package:
exclude:
- package-lock.json
- .gitignore
- .git/**
functions:
hello:
handler: index.hello
events:
- http:
path: /foo
method: get
package.json:
{
"name": "serverless-aliyun-hello-world",
"version": "0.1.0",
"description": "Hello World example for aliyun provider with Serverless Framework.",
"main": "index.js",
"license": "MIT"
}
index.js:
'use strict';
exports.hello = (event, context, callback) => {
const response = {
statusCode: 200,
body: JSON.stringify({ message: 'Hello!' }),
};
callback(null, response);
};
In order to deploy this function, we need the credentials with permissions to access Aliyun Function Compute. Please create a credentials file and configure the credentials in it. Here is an example credentials file:
[default] aliyun_access_key_id = xxxxxxxx aliyun_access_key_secret = xxxxxxxxxxxxxxxxxxxx aliyun_account_id = 1234567890
You can find the aliyun_access_key_secret and aliyun_access_key_id from https://ak-console.aliyun.com/?#/accesskey. You can also chose to create an Access Key or use sub-account Access Key. You can find the aliyun_account_id from https://account-intl.console.aliyun.com/?#/secure . After creating the credentials file, please make sure to change the credentials field value in serverless.yml to the absolute file path.
See test/project for a more detailed example (including how to access other Aliyun services, how to set up a HTTP POST endpoint, how to set up OSS triggers, etc.).
Make sure that you have activated Function Compute and any other dependent services such as RAM, Log Service, API Gateway and OSS before attempting to deploy your function.
Deploy your service to Aliyun:
If your service contains HTTP endpoints, you will see the URLs for invoking your functions after a successful deployment.
Note: you can use serverless deploy function --function <function name> to deploy a single function instead of the entire service.
Invoke a function directly (without going through the API gateway):
$ serverless invoke --function hello
Retrieve the LogHub logs generated by your function:
$ serverless logs --function hello
Get information on your deployed functions
When you no longer needs your service, you can remove the service, functions, along with deployed endpoints and triggers using:
Note: by default RAM roles and policies created during the deployment are not removed. You can use serverless remove --remove-roles if you do want to remove them.
Changing the region in provider of serverless.yml:
provider: name: aliyun region: cn-hongkong
Changing the region in CLI parameters:
$ serverless deploy --region cn-hongkong
Note: CLI parameter --region has higher priority than provider, But you have to add this parameter to all the invocations, not only deploy.
