## Features

• Checks status of each service registered in Kong, re-registers services which have stopped.
• Pre-configures Kong services based on environment variables

## How-to build

• Build the binary $ make

## How-to run

### Docker

docker run -it --link kong:kong ewanvalentine/kongbeat:latest \ 
       -host=kong \
       -admin-port=8001 \
       -proxy-port=80 \
       -pulse=10 

Standalone

./KongBeat -host=kong \
           -admin-port=8001 \
