rabotond/haproxy-consultemplate repository overview

1. Create your consul template file: /etc/htemplate/template.ctmpl
2. Run as: docker run -d -p 80:80 -v /etc/htemplate/template.ctmpl:/etc/htemplate/template.ctmpl rabotond/haproxy-consultemplate:3.0 [consul host ip address]

It will query your consul agent at the IP you give, and then reloads haproxy config every time when there is a change in Consul. You should edit your template file to match, the service in consul and also the port on which you backend is listening.
