Dikhao: A new way to look at EC2 & Route53

Dikhao is a project to cache every EC2 resource, find relations between them, and provide really fast lookups. It can be installed as a python command line utility (pip install dikhao), deployable in Heroku and has a ready to use hubot plugin.


Example search:

  • CLI command: $ batao -i route53.rohit.io
  • Hubot bot in hipchat: @hubot batao route53.rohit.io
  • Heroku App: http://<app_name>.herokuapp.com/lookup/route53.rohit.io

Note: Key ‘route53.rohit.io’ can be anything from the configurable list of indexed items (given below).

Example output:
