部署

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"'...

Generate Fun project successfully!
