Kong Path-Based Routing

Overview

This plugin will enable informing the hostname which Kong will route to based on elements in the request URI path. It allows for the concactination of both Regex' performed on the request URI path, and constants to form the routing hostname.

Example:

kong-path-based-routing-plugin 'host_fields' args:

[
  "$/api/service/(%S+)/",
  "$api/service/.*/v(%d+).",
  "$api/service/.*/v*..(%d+)",
  "-apitest.com"
]

on a request URI of https://kong-gateway/api/service/myapp/v1.0 to route with path: "/api" would route to host: myapp10-apitest.com/service/myapp/v1.0

The host given in the Service will not be used if this plugin is applied.

Supported Kong Releases

Kong >= 1.x

$ luarocks install kong-path-based-routing

Optional

$ luarocks make *.rockspec

Configuration

The plugin requires that regex's/constants be concatinated in the parameter "host_fields" to inform the upstream hostname. Strings given in the array begining with "$" will be treated as REGEX' to be applied to the URI path.
