阿里云函数计算（Function Compute）是一个事件驱动的全托管 Serverless 计算服务，您无需管理服务器等基础设施，只需编写代码并上传，函数计算会为您准备好计算资源，并以弹性、可靠的方式运行您的代码。类似于 AWS Lambda。
安装
npm install @alicloud/fun -g
# or
brew install fun
# fun --version
3.6.20
# fun --help

部署
以beego框架为例：
# fun deploy -y
current folder is not a fun project.
Fun detected your application doesn't listen on '0.0.0.0:9000' in /Users/xiexianbin/work/code/go/src/github.com/xiexianbin/x-lego/main.go
Fun will replace your addr to '0.0.0.0:9000', and also backup your origin file /Users/xiexianbin/work/code/go/src/github.com/xiexianbin/x-lego/main.go to /Users/xiexianbin/work/code/go/src/github.com/xiexianbin/x-lego/main.go.bak
? Are your sure? Yes
Tips:
You must use 'GOARCH=amd64 GOOS=linux go build -ldflags "-s -w"' to recompile your project every time before using fun deploy.
? Let Fun exec this command now for you? Yes
Executing command 'GOARCH=amd64 GOOS=linux go build -ldflags "-s -w"'...
