Automated DNS Management Coding Challenge (Ruby On Rails, July 2020)

A simple automated dns management system to manage hosted zones on Amazon Route53 service. Can add/remove predefined servers to subdomain of hosted domain/zone on AWS Route53.It supports only ipv4 addresses at moment.

It is hosted on Heroku (Link is removed)

How To Run

Install the latest version of Ruby , Rails and yarn.

Install dependencies

bundle install
yarn install

Run the App On Development Machine

rake db:migrate RAILS_ENV=development
rake db:seed RAILS_ENV=development
rails s

Navigate to http://localhost:3000/ and you should see dns entries

Run Tests

rubocop .

Set AWS Credentials in your environment

AWS_ACCESS_KEY_ID= {YOUR_AWS_ACCESS_KEY_ID}
AWS_SECRET_ACCESS_KEY= {YOUR_AWS_SECRET_ACCESS_KEY}

After setting environment variables restart might be reequire on Windows environment. At the moment , only one Route53 domain can be managed and it is configured in config\application.rb file as below

 config.zone_id = 'Z040251137DWBG4URKYPY' #AWS Route53 Hosted Zone ID
 config.domain_name = 'domain.com' # AWS Route53 Hosted Zone domain name

Note that, while development and test environments use Sqlite db , production environment requires postgresdb. This is something enforced and automaticall handled by Heroku.

How To Deploy Production

heroku git:remote -a xv-coding-challenge-nazmi-a

heroku run rake db:migrate
heroku run rake db:seed

To configure AWS Credentials on Heroku go to Heroku dashbaord, navigate to Application Settings -> Config Vars and set credential values by using same names (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY). In addition, setting AWS_REGION might be required.
