Epic seven gear optimizer

README

This README would normally document whatever steps are necessary to get the application up and running.

Things you may want to cover:

Ruby version

System dependencies

Configuration

Database creation

Database initialization

How to run the test suite

Services (job queues, cache servers, search engines, etc.)

Deployment instructions

We're going to deploy to Elastic Beanstalk, so make sure you have your AWS account and Access Key ID/Secret ready

Downloading and precompiling project

1. Clone this repo

   git clone https://github.com/BenjaminBLi/e7-gear-optimizer.git

2. cd into directory and install everything

   cd e7-gear-optimizer
   yarn install
   gem install bundler
   bundle install

3. Run rail server locally, check everything is fine

   rails s

4. Create new secret key and store in config/secrets.yml (save this key for EB env var later)

   export SECRET_KEY_BASE=$(rake secret)
   echo $SECRET_KEY_BASE

5. Precompile assets, run in production environment mode to double check its fine

   rake assets:precompile
   rails s -e production

Deploy to EB

1. Download EB CLI

2. In root directory, run eb init and fill in any information.

   • If you have not provided your Access Key ID/Secret, it will ask for this information.
   • Region is self explainatory
   • Application does not matter the name, just a way to organize different versions
   • Platform must be Ruby 2.7 running on 64bit Amazon Linux 2 (If you choose a existing application, this won't appear)
   • SSH for you instances needs to be on, because we'll need it in step 6.

3. Run eb create -s to launch a single instance of the app. You can name the environment and DNS prefix anything you'd like.

   • Note: that -s just means it will launch on a single instance instead of with a load balancer. In production, we might need this later, but for right now, single instance should server us well (and save us cash)

4. Launch the instance. This will produce an Error code 1, which is fine.

5. Set the SECRET_KEY_BASE

   • use command line

   eb setenv SECRET_KEY_BASE=$SECRET_KEY_BASE RAILS_SKIP_ASSET_COMPILATION=true RAILS_SKIP_MIGRATIONS=true

   • might need export RUBYOPT='-W:no-deprecated'

6. SSH into your instance using instance ec2-user and your Elastic Beanstalk DNS, Change the file in /etc/nginx/conf.d/elasticbeanstalk/webapp.conf

   eb ssh

   cd /etc/nginx/conf.d/elasticbeanstalk/
   sudo vi webapp.conf

   webapp.conf

   server_name _ localhost; # need to listen to localhost for worker tier
   
   location / {
       proxy_pass http://my_app; # match the name of upstream directive which is defined above
       proxy_set_header Host $host;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   }
   
   location /assets {
       alias /var/app/current/public/assets;
       gzip_static on;
       gzip on;
       expires max;
       add_header Cache-Control public;
   }
   
   location /packs {
       alias /var/app/current/public/packs;
       gzip_static on;
       gzip on;
       expires max;
       add_header Cache-Control public;
   }
   
   location /public {
       alias /var/app/current/public;
       gzip_static on;
       gzip on;
       expires max;
       add_header Cache-Control public;
   }
   

7. Restart nginx proxy server

   sudo su
   service nginx restart

   • Currently not sure if I can do this step automatically cause nginx overwrite my file I put here, and you might have to be in the nginx directory if you're having issues this restart
