Deploy Simple Go Webapp to Elastic Beanstalk
问题
我正在尝试通过 Elastic Beanstalk（通过 UI）部署一个 Go 应用程序。
我已经完成的工作：
- 创建了一个名为 application.go 的单个文件，它监听端口 5000。
- 使用以下命令将其编译为 Linux（设置 GOOS=linux 和 GOARCH=amd64）：https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/go-environment.html
- go build -o bin/application application.go
- 将 bin 文件夹压缩并上传到 Elastic Beanstalk（我也尝试过不带 bin 文件夹的上传文件）。
开发环境中，我使用的是 go 版本 go1.18.1 windows/amd64。
在 Elastic Beanstalk 的平台中，我看到：Go 1 运行在 64 位 Amazon Linux 2/3.5.1 上。
根据 https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platforms-supported.html#platforms-supported.go，go v. 1.18.1 是受支持的。
我的代码：
package main
import (
"fmt"
"net/http"
"time"
)
func main() {
http.HandleFunc("/", index)
fmt.Println("Now serving!!!")
http.ListenAndServe(":5000", nil)
}
func index(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "My Res !!! %s", time.Now())
}
应用程序的健康状态为 "no data"。
最近的事件是 "环境健康状态从 Pending 转换为 No Data。没有任何实例发送数据。"
当我在 Chrome 开发工具中尝试打开链接时，我只得到 (failed) net:ERR_CONNECTION_RESET。"Failed to load response data: No Resource with given identifier found"
可能的问题：
- 当我查看配置选项卡时，我发现此环境不属于 VPC。这可能是问题吗？
一些可能的下一步操作：
- 在 WSL 上进行测试运行
- 在独立的 EC2 上进行测试部署
- 尝试通过 CLI 进行部署
- 尝试将其包装在 Docker 容器中并进行部署（尽管这不会解决我的问题，但我希望能够在没有 Docker 的情况下进行部署）
英文:
I am trying to deploy a Go app to Elastic beanstalk (through the UI)
What I've done:
- Created a single application.go file which listens on Port 5000
- Compiled for Linux (set GOOS=linux and GOARCH=amd64) using the command found here: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/go-environment.html
- go build -o bin/application application.go
- zipped the bin folder and uploaded it to Elastic Beanstalk (I've also tried uploading the file without the bin folder)
For development I'm using go version go1.18.1 windows/amd64
Under Platform in Elastic Beanstalk I see: Go 1 running on 64bit Amazon Linux 2/3.5.1
According to https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platforms-supported.html#platforms-supported.go
go v. 1.18.1 is supported
My Code:
package main
import (
"fmt"
"net/http"
"time"
)
func main() {
http.HandleFunc("/", index)
fmt.Println("Now serving!!!")
http.ListenAndServe(":5000", nil)
}
func index(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "My Res !!! %s", time.Now())
}
The Application health is "no data".
With the most recent event of "Environment health has transitioned from Pending to No Data. None of the instances are sending data."
When I look in chrome dev tools and try to open the link, I just get (failed) net:ERR_CONNECTION_RESET. "Failed to load response data: No Resource with given identifier found"
Potential Issues:
- When I look at the configuration tab, I see that this environment is not part of a VPC. Could that be the issue?
Some Potential Next Steps:
- Test running on WSL
- Test deploying on a standalone EC2
- Try deploying through the CLI
- Try wrapping in a docker container and deploying docker (though this wouldn't actually solve my problem, I'd like to be able to deploy without docker)

我尝试使用你的代码复制了你的问题，但是一切正常。我的 EB 环境可以正常运行并且使用你的代码进行部署。
我唯一能想到的是我使用的是 Linux 来创建二进制文件，而你使用的是 windows/amd64。我认为这些二进制文件是不可互换的。
英文:
I tried to replicate your issue using your code, but everything is fine. My EB environment works and deploys perfectly with your code.
The only thing I can think of is that I used linux to create my binary, while you've used windows/amd64. I don't think those binaries are interchangeable.
