README

A reverse proxy written in go that can front any number of microservices. It uses a rules file to map from requested host/path to microservice host/port/path. Example rule file:

	[
	  {
	    "host": "domain.com",
	    "path": "/login",
	    "forward": "localhost:9004",
	    "secure": false
	  },
	  {
	    "host": "domain.com",
	    "path": "/ds/",
	    "forward": "localhost:8081",
	    "secure": true,
	    "capabilities": {
	        "GET": "read-ds",
	        "POST": "write-ds",
	        "PUT": "write-ds",
	        "PATCH": "write-ds"
	    }
	  },
	  {
	    "host": "domain.com",
	    "path": "/cachegroups/",
	    "forward": "localhost:8082",
	    "secure": true,
	    "capabilities": {
	        "GET": "read-cg",
	        "POST": "write-cg",
	        "PUT": "write-cg",
	        "PATCH": "write-cg"
	    }
	  }
	]

Note: Access "capabilities" are set in the rule file as a workaround, until TO DB tables are ready.

No restart is needed to re-read the rule file and apply; within 60 seconds of a change in the file, it will pick up the new mappings.
