阿里云 函数计算

使用简介#

产品页开通服务。使用流程,如下:

新手示例,如下:

创建函数#

阿里云提供了如下几种方式创建函数:

以下为使用 VSCode 插件创建函数。

前提准备#

安装软件#

安装插件#

插件: Aliyun Serverless VSCode Extension

VSCode 插件市场搜索 "aliyun" ,安装:

左侧边栏,打开插件,绑定账户:

依次输入 Account ID, AccessKey ID, AccessKey Secret, Account Alias 。

绑定后, "REMOTE RESOURCES" 可以看到该账户的云端服务与函数列表。

本地创建#

"LOCAL RESOURCES" 面板 "+" 创建函数:

输入内容:

service name: demo
function name: test
function runtime: nodejs12
function type: NORMAL (Event Trigger)

本地运行#

函数名称上 "Local Run" 运行:

函数日志,输出在终端。

远程部署#

"LOCAL RESOURCES" 面板 "Deploy" 部署函数:

"REMOTE RESOURCES" 可查看部署的函数。

或者到阿里云函数计算控制台查看:

部署 Docusaurus#

环境准备#

安装 Funcraft#

Funcraft 是函数计算提供的一种命令行工具,通过该工具,您可以便捷地管理函数计算、API网关、日志服务等资源。通过一个资源配置文件 template.yml , Funcraft 即可协助您进行开发、构建、部署操作。

npm 安装:

npm install @alicloud/fun -g

fun 版本:

❯ fun --version
3.6.18

fun 配置:

❯ fun config
? Aliyun Account ID ***********
? Aliyun Access Key ID ***********AmpG
? Aliyun Access Key Secret ***********XZlY
? Default region name cn-shanghai
? The timeout in seconds for each SDK client invoking 60
? The maximum number of retries for each SDK client 3
? Allow to anonymously report usage statistics to improve the tool over time? Ye
s
? Use custom endpoint? No

创建应用#

npx @docusaurus/init@next init my-site classic

运行:

cd my-site
yarn start

效果:

部署应用#

❯ cd my-site

初始化:

❯ fun init
? Select a template to init http-trigger-nodejs12
? You've created /users/ikuokuo/start-serverless/my-site before. Is it okay to override it? Yes
Start rendering template...
+ /users/ikuokuo/start-serverless/my-site
+ /users/ikuokuo/start-serverless/my-site/.funignore
+ /users/ikuokuo/start-serverless/my-site/index.js
+ /users/ikuokuo/start-serverless/my-site/template.yml
finish rendering template.

删除 index.js

rm index.js

修改 template.yml

创建 bootstrap

cat <<EOF >bootstrap
#!/usr/bin/env bash
export PORT=9000
npm run serve -- --port \$PORT
# yarn serve --port \$PORT
EOF
chmod a+x bootstrap

Something is already running on port: https://github.com/facebook/docusaurus/issues/3505. Check npx docusaurus --version >= 2.0.0-alpha.66 !

编译:

yarn build

部署:

❯ fun deploy
using template: template.yml
using region: cn-shanghai
using accountId: ***********
using accessKeyId: ***********AmpG
using timeout: 60
