Elastic Beanstalk Procfile for go - amazon-web-services

Question

I'm trying to deploy my go restful server program to EC2 Linux using Elastic Beanstalk. The document says that I need to create a Procfile at the root. So I did. Here are the steps:
Build my go program myapp.go to using
$ go build -o myapp -i myapp.go
Create a Procfile with exact name at the root with
web: myapp
Zip up the Procfile and the myapp image to a myapp.zip file.
Upload to the server via Elastic Beanstalk console. But I keep getting Degraded health and warning with
WARN Process termination taking longer than 10 seconds.
Any suggestions. By the way, I tried to use the same procfile procedure on the simple application.go zip file came from the Elastic Beanstalk example library. It didn't work either.

I was finally able to get a Go application to deploy with Elastic Beanstalk using the eb client. There are a few things that EB requires:
The name of your main file should be application.go.
Make sure your app is listening on port 5000.
You'll need a Procfile in the main root with
web: bin/application
You'll need a Buildfile with
make: ./build.sh
And finally you'll need a build.sh file with
#!/usr/bin/env bash
# Stops the process if something fails
set -xe
# All of the dependencies needed/fetched for your project.
# FOR EXAMPLE:
go get "github.com/gin-gonic/gin"
# create the application binary that eb uses
GOOS=linux GOARCH=amd64 go build -o bin/application -ldflags="-s -w"
Then if you run eb deploy (after creating your initial eb repository), it should work. I wrote a whole tutorial for deploying a Gin application on EB here. The section specifically on deploying with Elastic Beanstalk is here.
