Feign Ranger Travis build status

This is a [feign] (https://github.com/Netflix/feign) extension that supports using ranger discovered nodes as target. Also, this extension supports other modules like feign-hystrix which allows the http calls are wrapped inside a Hystrix command which allows granular control of execution environment. This library compiles only on Java 8.

Dependencies

  • ranger 0.6.3
  • feign 10.7.4

Usage

Feign Ranger extension provides a easy way to enable providing service node discovery environments. Using service discovery with feign brings the ease of use of feign in a dynamic environment where providing target host port is counter productive or not possible (when applications are running in mesos/dcos).
