+HAProxy reverse proxy for high availability environments.
+
+## Summary
+
+- Dockerfile - build container image with haproxy.
+- openshift-template.yml - Template for OpenShift to haproxy.
+
+## How to use the container
+
+* Copy ```./examples/haproxy.cfg``` to ```/etc/haproxy/haproxy.cfg```
+* Run two HTTPD servers on ```IP1```:```port1``` and ```IP2```:```port2```
+* Modify ```/etc/haproxy/haproxy.cfg``` so it uses relevant addresses and ports.
+ 
+Command for running haproxy docker container:
+
+```bash
+docker run -it n
+```
+
+## How to run haproxy as standalone container
+
+Copy haproxy-container.service to ```/usr/lib/systemd/system/``` directory
+```bash
+sudo cp haproxy-container.service /usr/lib/systemd/system/
+systemctl daemon-reload
+```
+
+Command for running memcached as standalone container:
+```bash
+systemctl start haproxy-container
+```
+
+## How to stop memcached as standalone container
+Command for stopping haproxy as standalone container:
+```bash
+systemctl stop haproxy-container
+```
+## How to test the haproxy

+# NAME
+haproxy - HAProxy reverse proxy for high availability environments.
+
+# DESCRIPTION
+HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments.
+
+The container itself consists of:
+    - fedora/26 base image
+    - haproxy RPM package
+
+Files added to the container during docker build include: /files/haproxy.sh
+
+# USAGE
+To get the memcached container image on your local system, run the following:
+
+    docker pull hub.docker.io/phracek/haproxy 
+    
+# SECURITY IMPLICATIONS 
+Lists of security-related attributes that are opened to the host.
+
+-p 80:80
+    Opens container port 80 and maps it to the same port on the host.
