Go&Docker:当我使用stdlib时,我能够运行go web服务器,当我使用自定义包时会发生错误

Question

请注意,当我在笔记本电脑上运行代码时,代码完全正常.

以下两组代码将在我的笔记本电脑上运行.但是第二组(使用我的自定义程序包)不适用于运行docker的Elastic Beanstalk.

仅限标准Lib

import (
    "net/http"
    "os"
)

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = "3000"
    }
    http.ListenAndServe(":"+port, nil)
}

使用自定义包

import (
    "os"

    "github.com/sim/handlers"
)

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = "3000"
    }
    handlers.ServeAndHandle(port) // wrapper of ListenAndServe
}

错误消息:

根据文档，您的环境需要一个Dockerfile或/和Dockerrun.aws.json

Dockerfile

FROM FROM golang:1.3-onbuild

EXPOSE 3000

CMD ["go run <your.go.file>"]

Dockerrun.aws.json

{
  "AWSEBDockerrunVersion": "1",
  "Image": {
    "Name": "golang:1.3-onbuild",   # <-- don't need this if you are using a Dockerfile
    "Update": "true"
  },
  "Ports": [
    {
      "ContainerPort": "3000"
    }
  ],
  "Logging": "/var/log/go"
}

使用eb命令行部署？
