英文:
Deploying golang app in cmd folder to AWS Beanstalk
问题
我有一个现有的golang项目,具有以下文件夹结构(为了可读性而缩小了文件夹)。
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
- main.go
- vano
现在,由于我的项目Web服务器位于./cmd/vano
,我需要创建一个自定义的Buildfile
和Procfile
。所以我这样做了
这是我的Buildfile
make: ./build.sh
build.sh文件:
#!/usr/bin/env bash
安装依赖项。
go get ./...
构建应用程序
go build ./cmd/vano -o bin/application
最后是我的Procfile:
web: bin/application
所以现在我的文件夹结构如下:
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
Buildfile
build.sh
Procfile
- main.go
- vano
我使用git将源代码打包:
git archive --format=zip HEAD > vano.zip
然后将其上传到AWS Beanstalk。然而,我一直收到错误消息,而AWS的错误似乎并不是最易读的。这是我的错误信息
所有实例上的命令执行已完成。摘要:[成功:0,失败:1]。
错误消息
[Instance: i-0d8f642474e3b2c68]实例上的命令执行失败。返回代码:1 输出:(已截断)...'无法执行'HOME=/tmp /opt/elasticbeanstalk/lib/ruby/bin/ruby /opt/elasticbeanstalk/lib/ruby/bin/foreman start --procfile /tmp/d20170213-1941-1baz0rh/eb-buildtask-0 --root /var/app/staging --env /var/elasticbeanstalk/staging/elasticbeanstalk.env'。钩子/opt/elasticbeanstalk/hooks/appdeploy/pre/01_configure_application.sh失败。有关详细信息,请使用控制台或EB CLI检查/var/log/eb-activity.log。
额外的错误信息:

英文:
I have a pre-existing golang project with the a following folder structure (minimized the folder for readability).
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
Now since my project web server is in ./cmd/vano
I need to create a custom Buildfile
and Procfile
. So I did that
Here is my Buildfile
make: ./build.sh
build.sh file:
#!/usr/bin/env bash
# Install dependencies.
go get ./...
# Build app
go build ./cmd/vano -o bin/application
and finally my Procfile:
web: bin/application
So now my folder structure looks like this:
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
Buildfile
build.sh
Procfile
I zip up the source using git:
git archive --format=zip HEAD > vano.zip
And upload it to AWS Beanstalk. How ever I keep getting errors and AWS errors don't seem to be the most read. Here is my error
Command execution completed on all instances. Summary: [Successful: 0, Failed: 1].
Error Message
[Instance: i-0d8f642474e3b2c68] Command failed on instance. Return code: 1 Output: (TRUNCATED)...'

这里还有另一种方法,而不是使用procfile等方式,可以通过交叉编译你的二进制文件(在Go语言中通常很简单),然后按照指南中的简单说明上传它:
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/go-environment.html
你可以在本地进行编译:
GOARCH=amd64 GOOS=linux go build -o bin/application ./cmd/vano
然后将应用程序文件打包成zip文件上传,假设你的设置只需要这一个二进制文件来运行,应该就可以工作了。
英文:
Another approach here instead of using a procfile etc would be to cross-compile your binary (usually pretty painless in go) and upload it that way, as per the simple instructions in the guide:
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/go-environment.html
You can just compile it locally with:
GOARCH=amd64 GOOS=linux go build -o bin/application ./cmd/vano
Then upload zip of the application file and it should work, assuming your setup only requires this one binary to run.

部署的最佳方式是使用命令行创建一个二进制文件。
在终端中使用以下命令创建一个二进制文件:go build -o bin/application application.go
然后将所有文件添加到一个 zip 文件中。
进入您的 eb 环境并上传该 zip 文件。
