Can you run a rails console or rake command in the elastic beanstalk environment?

Question

I have set up a RoR environement on AWS\' elastic beanstalk. I am able to ssh into my EC2 instance. My home directory is /home/ec2-user, which is effective

Answer 1

None of these were working for me, including the aws-console script. I finally ended up creating a script directory in /var/app/current and then creating a rails file in that directory as outline by this answer on another SO question.

eb ssh myEnv
cd /var/app/current
sudo mkdir script
sudo vim script/rails

Add this to file and save:

echo #!/usr/bin/env ruby
# This command will automatically be run when you run "rails" with Rails 3 gems installed from the root of your application.

APP_PATH = File.expand_path('../../config/application',  __FILE__)
require File.expand_path('../../config/boot',  __FILE__)
require 'rails/commands'

Then make it executable and run it:

sudo chmod +x script/rails
sudo script/rails console

And it worked.

Answer 2

#!/bin/sh

shell_join () {
  ruby -r shellwords -e 'puts Shellwords.join(ARGV)' "$@"
}


command_str () {
  printf 'set -e; . /etc/profile.d/eb_envvars.sh; . /etc/profile.d/use-app-ruby.sh; set -x; exec %s\n' "$(shell_join "$@")"
}

exec sudo su webapp -c "$(command_str "$@")"

Put above file somewhere in your source code, deploy, eb ssh into the eb instance, cd /var/app/current, and then execute path/to/above/script bin/rails whatever argumeents you usually use.

Reason why I have written above script is:

1. When using sudo, it drops some environment variables which might actually be needed for your rails app; so manually load the profiles which the Elastic Beanstalk platform provides.
2. Current Beanstalk ruby platform assumes you run rails application on user webapp, a non-login-able user, so it would be wise to run your command in this user.

Answer 3

For rails, jump to /var/app/current then as @juanpastas said, run RAILS_ENV=production bundle exec rails c

Answer 4

None of these solutions mentioned here worked for me, so I cooked up a little script that I put in script/aws-console.

You can run it from the /var/app/current directory as root:

eb ssh
cd /var/app/current
sudo script/aws-console

My script can be found as a Gist here.

Answer 5

Don't know why, but since EBS runs everything as root, this worked for me:

sudo su
bundle exec rails c production
