+# CentOS-7 with HAProxy
+
+This is a [million12/centos-haproxy](https://registry.hub.docker.com/u/million12/centos-haproxy/) docker container with HAProxy load balancer. This work is very similar to official [dockerfile/haproxy](https://registry.hub.docker.com/u/dockerfile/haproxy/), but it's based on CentOS-7 and, more importantly, offers ability to provide any arguments to haproxy process. It's also pretty lightweight, only ~230M (vs. ~420M Ubuntu-based dockerfile/haproxy).
+
+This container is built with `ENTRYPOINT` set to `haproxy`, so when you run it, it behaves as you'd run haproxy binary. Therefore **you can pass any extra options, which will be passed directly to haproxy**.
+
+The default [haproxy.cfg](haproxy/haproxy.cfg) is provided just for demonstration purposes, so of course you will want to override it.
+
+## Usage
+
+### Basic
+
+`docker run -ti -p 80:80 -p 443:443 million12/centos-haproxy -f /etc/haproxy/haproxy.cfg`
+
+### Mount custom config, override some options
+
+`docker run -d -p=80:80 -p=443:443 -v=/data/haproxy/haproxy.cfg:/etc/haproxy/haproxy.cfg million12/centos-haproxy -f /etc/haproxy/haproxy.cfg -n 10000`
+
+### Check version and build options
+
+`docker run -ti million12/centos-haproxy`
