Deploy to Ruby on Rails Elastic beanstalk (Environment construction)

Overview

Deploy an application created with Ruby on Rails Use Elastic Beanstalk (EB) to build an environment in the shortest possible time. It is divided into IAM authority change, environment construction, and EB deployment. We will focus on deploying quickly, so please be aware of this if you need strict control.

About the development environment

Ruby ・ ・ ・ 2.6.3 Rails ・ ・ ・ 5.0.7.2 Bundler ・ ・ ・ 2.1.4 or above OS ・ ・ ・ amazon Linux (cloud9) Rails was a little troublesome for SECRET_KEY ver management after 5.2, and 6.0 and above are still new (although I have not caught up with it), so there was no merit to raise the ver, so ver5.0.7. I'm using 2.

Since it is basically Linux, I think that the same operation can be performed on a Mac. However, in the free frame of cloud9, capacity is required due to rbenv, Ruby ver change, etc., and it has been expanded by about 10GB. It's OK to fold it as soon as you can deploy it, but is it actually around 500 even in a month?

Environment

1. rbenv install

git clone https://github.com/sstephenson/rbenv.git ~/.rbenv

2. Put build as a plugin

mkdir -p ~/.rbenv/plugins

3. Install (clone) ruby-build in ~ / .rbenv

cd ~/.rbenv/plugins
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

4. Add to PATH → Add rbenv init to .bash_profile → Enable information added to path

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
exec $SHELL -l

5. Check rbenv → Check the list that can be installed

rbenv -v
rbenv install --list

6. Select the specified ver (2.6.5 this time)

rbenv install 2.6.5

7. Set the installed version to global for the entire environment (please set it to local if there are other apps)

rbenv global 2.6.5

8. Reload the set rbenv

rbenv rehash

9. Specify the bundler ver and install

gem install bundler -v 2.1.4

10. Rails new by specifying ver of rails

rails _5.0.7.2_ new myapp

11. Addition of gem (It is safe to put what is necessary for development here and check the deployment in advance) pg, sqlite 1.3.6 or higher (pg can support heroku. sqlite specifies 1.3.6 or higher for cloud9. Dotenv-rails uses environment variables, so I will include it this time.)

gem 'sqlite3','~> 1.3.6'
gem 'pg'
gem 'dotenv-rails'

12.bundle install

myapp

bundle install --path vendor/bundle

13. Added to gem file, pg, sqlite 1.3.6 or higher (pg can support heroku. sqlite is cloud9)

Gemfile

gem 'sqlite3','~> 1.3.6'
gem 'pg'
gem "dotenv-rails"

14. Install while setting high-speed install with 4 cores (-j4 does not need to be entered in the future because it enters bundle config)

myapp

bundle install -j4

15. Checking the operation of the app

myapp

rails g scaffold message subject body:text
rails db:create
rails db:migrate
rails s

Check the connection to the localserver of rails here. Thank you for your hard work.

Next, I will create a user with EB authority in IAM. It is not good to operate EB with Root authority, and it is not recommended to create an access key for Root.
