Aliyun Function Compute Serverless Plugin
This plugin enables Aliyun Function Compute support within the Serverless Framework.
Getting started
Pre-requisites
- Node.js v8.x for using the plugin.
- Serverless CLI v1.26.1+. You can get it by running
npm i -g serverless
. - An Aliyun account.
Example
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-worldprovider: name: aliyun runtime: nodejs8 credentials: ~/.aliyun_credentials # path must be absoluteplugins: - serverless-aliyun-function-computepackage: 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 = xxxxxxxxaliyun_access_key_secret = xxxxxxxxxxxxxxxxxxxxaliyun_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.).
Workflow
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:
$ serverless deployIf 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
$ serverless info -
When you no longer needs your service, you can remove the service, functions, along with deployed endpoints and triggers using:
$ serverless removeNote: 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.
Change Region
-
Changing the region in provider of serverless.yml:
provider:name: aliyunregion: cn-hongkong -
Changing the region in CLI parameters:
$ serverless deploy --region cn-hongkongNote: CLI parameter
--region
has higher priority than provider, But you have to add this parameter to all the invocations, not onlydeploy
.
