[![Build Status](https://travis-ci.com/fretlink/ansible-kong-app.svg?token=D3nFpUxMu7vStDHwUNy4&branch=master)](https://travis-ci.com/fretlink/ansible-kong-app)

This role aims at creating, on a remote kong, a list of services, routes and plugins needed by an app. The API calls are made from the ansible target host. If you use `hosts: localhost` as a target from within your playbook then all API calls will be done from your local machine.

Requirements
------------

A Kong server which you want to configure.

If you want to configure this role with [Dhall](https://dhall-lang.org/) instead of YAML, the role publishes dhall bindings defined in the `dhall/package.dhall` file. These bindings will need Dhall version `1.29.0` or higher.
