This is my submission for the Infrastructure / Site Reliability Engineering Intern Technical Challenge. My extra feature is "Ability to create warehouses/locations and assign inventory to specific locations"

This project uses Ruby 2.7.3. If you don't have Ruby already installed, follow the instructions below

• Install rbenv on your specific system and follow setup
• Install ruby with rbenv install 2.7.3
• Set local ruby version with rbenv local 2.7.3

• Install Ruby 2.7.3 using other methods

(Required)

• PostgreSQL

Follow the instructions on the Postgres website to download Postgres >= 9

Make sure PostgreSQL is started up on your computer.

Note that if your environment paths are not set up correctly, you may have to run bin/rails [COMMAND] instead of the normal rails command.

rails db:create

rails db:migrate
# Optional, if you want to seed with fake data 
rails db:seed 

Test are located in the test/ folder.

rails t

# Only needed on initialization of production database  
rails db:create -e production

rails db:migrate -e production 
rails s -e production 

The app includes

• rate limiting via Rack::Attack middleware
• healthcheck endpoint at /healthcheck
• slugs for warehouses (though still easily viewable via model ID in the backend)
• Custom logging with timestamps
• DB Timeouts

All available URLS can be seen with

bin/rails routes

You can view UML diagrams in the docs/ folder for a better understanding of the schema. To generate new diagrams, run

rake diagram:all

Models (and their respective validations) can be seen in the app/models/ folder
