Rails 7. Start Kit

Rails 7 App with Preinstalled Tools is Ready in Minutes!

Why?

Usually It is difficult and time consuming to setup a typical Rails environment from scratch.

Since now if you have Ruby and Docker then you have working Rails environment in about 5 minutes without any manual efforts.

Conventions and Agreements

For demonstration, education and maintainance purposes I use the following approach:

Data

• All services' data related folders are placed in ./db
• All folders are UPPERCASED

./db
├── ELASTIC
├── PGSQL
└── REDIS

Configuration Files

• All services' configurations are placed in ./config
• All configs are _UNDERSCORED and UPPERCASED

./config
├── _CONFIG.yml
├── _PUMA.rb
├── _SIDEKIQ.yml
└── _THINKING_SPHINX.yml

Initialazers

• All services' initializers are placed in ./config/initializers
• All files are _UNDERSCORED and UPPERCASED

./config/initializers/
├── _CHEWY.rb
├── _CONFIG.rb
├── _REDIS.rb
└── _SIDEKIQ.rb

Rails user

As a user to own files and run Rails inside a container I use

user:group => lucky:lucky => 7777:7777

If you would like to run the project on a linux environment then:

• create group lucky (7777) and user lucky (7777)
• run the project with RUN_AS=7777:7777 option

How to Run Tests

From the root of the project

  bin/open rails

Now you are in the Rails container and you can do everything as usual

  RAILS_ENV=test rake db:create
  rake test
