→building the docker image

The second problem is that they are all based on ubuntu image, that makes it very difficult to get rsyslog to log on to stdout, which required by the Kubernetets centralized log collector system for retaining HAproxy logs. We are going to port the original grok Dockerfile to '''centos 7''' base image and will add rsyslog installation to the new image.
