Deploy Ruby on Rails (RoR) to AWS Elastic Beanstalk.
Configure the Create a web server environment page as follows:
- Platform
- Preconfigured platform: Ruby
- Base configuration
- Application code: Sample application
Click Create environment – AWS will begin creating a Ruby environment, including a basic credentials file.
Note the version of Ruby (e.g. 2.6).
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ruby-rails-tutorial.html
An easy way to accomplish this is to install and use the Ruby Version Manager.
$ rvm use 2.6.3
$ gem install rails
$ rails new eb-rails
This step is for documentation, as this repository is already comprised of a Rails project.
https://github.com/reactjs/react-rails
If uploading and deploying from this repository, then skip to Upload and Deploy to AWS Elastic Beanstalk.
Add webpacker and react-rails to your gemfile:
gem 'webpacker'
gem 'react-rails'
Now run the installers:
$ bundle install
$ rails webpacker:install # OR (on rails version < 5.0) rake webpacker:install
$ rails webpacker:install:react # OR (on rails version < 5.0) rake webpacker:install:react
$ rails generate react:install
Link the JavaScript pack in Rails view using javascript_pack_tag helper:
<!-- application.html.erb in Head tag below turbolinks -->
<%= javascript_pack_tag 'application' %>
Add the following .ebextensions config script to update Bundler: gem_install_bundler.config
# Updates Bundler so that Rails can be uploaded and deployed to AWS Elastic Beanstalk.
# https://github.com/shakacode/react_on_rails/blob/master/docs/additional-reading/elastic-beanstalk.md

cd $EB_APP_STAGING_DIR
echo "Installing compatible bundler"
gem install bundler -v 2.0.2
Add the following .ebextensions config script to update Node.js and install Yarn for deployment of React: react-rails.config
# Updates Node and installs Yarn so that React-Rails can be uploaded and deployed to AWS Elastic Beanstalk.
# https://github.com/shakacode/react_on_rails/blob/master/docs/additional-reading/elastic-beanstalk.md

yum -y install yarn;

Add the following .ebextensions config script to configure NGINX to serve React /packs: nginx.config
# Modifies webapp_healthd.conf to allow React-Rails requests for /packs.
files:

container_commands:
nginx_reload:
command: "sudo service nginx reload"
This repository already includes gem_install_bundler.config, react-rails.config, and nginx.config.
Include a master key via config/master.key or by configuring it in your AWS Elastic Beanstalk Ruby environment property RAILS_MASTER_KEY. If including the master key via config/master.key, don't commit the file; instead, put the master key in a password manager. By default, both Rails and this repository .gitignore config/master.key.
Create a source bundle containing the files created by Rails. The following command creates a source bundle named rails-default.zip.
$ cd eb-rails
$ zip ../rails-default.zip -r * .[^.]* -x@.exclude.lst
Upload and deploy the source bundle to the AWS Elastic Beanstalk Ruby environment.

Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/11_asset_compilation.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.
Include a master key. See Include credentials.
If a master key has never been created for this project, then create the credentials by running the following command:
$ rails credentials:edit
On successful execution, the command will create two files:
- config/credentials.yml.enc
- config/master.key
Remember, for security reasons, do not commit master.key to the repo.
