How do you install Go dependencies when deploying to Elastic Beanstalk?

I have an application that's split across a few different files and I'm having trouble deploying it. I've followed this documentation, but I'm getting the following:

application.go:7:5: cannot find package "github.com/gorilla/handlers" in any of:

I assume I need to install the libraries I'm using in the $GOPATH as part of the deployment process, but I don't know how to do that and haven't found any examples of it. Using the Procfile seems promising, but all of my searches keep leading me to Heroku resources.

This works for me as of mid-2019. The gist is to compile locally and upload your binary. Run this from your project root:

GOARCH=amd64 GOOS=linux go build -o bin/application

Then include this binary in your application zip that you upload to the EB console.

I ran into the same issue, and was able to fix it by using the eb client.

Just to cover the basics:

  1. The name of your main file should be application.go.

  2. Make sure your app is listening on port 5000.

  3. You'll need a Procfile in the main root with

    web: bin/application

  4. You'll need a Buildfile with

    make: ./build.sh

  5. 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.
# This is what actually fixes the problem so that EB can find your dependencies. 
# 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 inital eb replository), it should work. I think you can get the same results by then zipping your application.go, Procfile, Buildfield, and build.sh script and loading that into the Elastic Beanstalk console, but I haven't tried it.

I wrote a whole tutorial for deploying a Gin application on EB here. The section specifically on deploying with Elastic Beanstalk is here.

You could use a vendoring tool to store all your dependencies within a vendor folder.

I use govendor.

Steps:
 1. go get -u github.com/kardianos/govendor
 2. cd $GOPATH/yourProject
 3. govendor init
 4. govendor add +external

Now the directory 'yourProject' can be build independently on any machine provided it is in $GOPATH.

Note : Requires Go 1.6+ or 1.5 with GO15VENDOREXPERIMENT=1.

Edit : As per fl0cke's comment. If Elastic Beanstalk only supports Go 1.4, the possible options are :
