How do I deploy a Go app with modules to AWS EB - amazon-web-services

Question

When I deploy the app, it runs fine on first install. But any following eb deploy procedures fail with an error that: go.mod was found, but not expected.
Is there a specific configuration I have to set for deploying with Go modules?
I switched to Dockerizing the app and deploying that way, which works fine. But it sounds a bit cumbersome to me as AWS Elastic Beanstalk provided specific Go environments.

Answer 1

You can work with go modules.
build.sh
#!/usr/bin/env bash
set -xe
# get all of the dependencies needed
go get
# create the application binary that EB uses
go build -o bin/application application.go
and override GOPATH to point to $HOME which defaults to /var/app/current as given in the EB configuration management dashboard.
.ebextensions/go.config
option_settings:
aws:elasticbeanstalk:application:environment:
GOPATH: /home/ec2-user

I had the same problem, I was finally able to fix it adding this line in my build.sh script file:
sudo rm /var/app/current/go.*
So it is like this, in my case:
#!/usr/bin/env bash
# Stops the process if something fails
set -xe
sudo rm /var/app/current/go.*
# get all of the dependencies needed
go get "github.com/gin-gonic/gin"
go get "github.com/jinzhu/gorm"
go get "github.com/jinzhu/gorm/dialects/postgres"
go get "github.com/appleboy/gin-jwt"
# create the application binary that eb uses
GOOS=linux GOARCH=amd64 go build -o bin/application -ldflags="-s -w"
