本示例基于golang iris的Hello World，静态编译，基于空白镜像scratch，解决了时区问题

创建一个webserver项目

go mod init webserver

main.go

package main

import (
    "time"

    "github.com/kataras/iris/v12"
    "github.com/kataras/iris/v12/mvc"

    "github.com/kataras/iris/v12/middleware/logger"
    "github.com/kataras/iris/v12/middleware/recover"
)

func newApp() *iris.Application {
    app := iris.New()

    app.Use(recover.New())
    app.Use(logger.New())

    mvc.New(app).Handle(new(ExampleController))

    return app
}

func main() {
    app := newApp()

    app.Listen(":8080")
}

type ExampleController struct{}

func (c *ExampleController) Get() mvc.Result {
    return mvc.Response{
        ContentType: "text/html",
        Text:        "当前时间：" + time.Now().Format("2006-01-02 15:04:05"),
    }
}

func (c *ExampleController) GetPing() string {
    return "pong"
}

func (c *ExampleController) GetHello() interface{} {
    return map[string]string{"message": "Hello Iris!"}
}

func (c *ExampleController) BeforeActivation(b mvc.BeforeActivation) {
    anyMiddlewareHere := func(ctx iris.Context) {
        ctx.Application().Logger().Warnf("Inside /custom_path")
        ctx.Next()
    }
    b.Handle("GET", "/custom_path", "CustomHandlerWithoutFollowingTheNamingGuide", anyMiddlewareHere)
}

func (c *ExampleController) CustomHandlerWithoutFollowingTheNamingGuide() string {
    return "hello from the custom handler without following the naming guide"
}

构建

GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -ldflags -s -a -installsuffix cgo main.go 

Dockerfile

FROM scratch

ENV TZ=Asia/Shanghai
