The current openshift router images uses the Red Hat RPM package of haproxy. This package is maintained by Red Hat and uses haproxy 1.5 with some Red Hat patches.
You can see what’s in the package on centos git repo
It’s not bad but haproxy have now released the version 1.7.x, therefore there are several enhancements and bugfixes in the newer versions.
To be able to use the haproxy 1.7 you will need to build your own router as in the old days when you wanted to change something in the haproxy config template file.
UPDATE: There is now a image on docker hub as described in How to use haproxy 1.7 in openshift router (part 2)
Now we have the possibility to change the haproxy config template via a configmap, thanks to the developers which have added this feature by default into the openshift router.
First of all the processes for the Openshift Origin and Openshift Container Platform (OCP) are the same. The difference is the repository and the subscriptions.
Now let’s start.
Create a new project where this new routers are build and run.
oc new-project new-routers
Now create the images
and wait until the build and push to the registry is done.
You can follow the build logs via the following command.
oc logs -f bc/openshift-origin-router-hap17 # or oc logs -f bc/openshift-oscp-router-hap17You have now a router image with a new haproxy.
Here is the output of haproxy -vv

Why should I use a newer haproxy?
Well first of all it’s a coolness factor ;-)
