将cmd文件夹中的golang应用程序部署到AWS Beanstalk

Question

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

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.
