HAProxy is being removed from the haproxy-router image in 5.1; use the dedicated haproxy-router-haproxy32 (HAProxy 3.2) payload component instead.

The haproxy-router-haproxy32 image differs from the old haproxy-router image in two ways that break the on-prem haproxy static pod: it does not ship the /var/lib/haproxy/run directory, and it runs as a non-root user by default. Both cause haproxy to crashloop when binding the stats socket at /var/lib/haproxy/run/haproxy.sock. Create the directory before starting haproxy and set runAsUser: 0 (allowed under the pod's privileged SCC) to restore the prior behavior.

Run HAProxy as non-root and provide a writable runtime mount.
runAsUser: 0 runs HAProxy and its startup script as root. The script creates /var/lib/haproxy/run, but run-dir is mounted at /var/run/haproxy, so the runtime path remains on the root filesystem. Mount a correctly owned writable volume at /var/lib/haproxy/run, then set runAsNonRoot: true, readOnlyRootFilesystem: true, and allowPrivilegeEscalation: false. Confirm the HAProxy 3.2 image supports the selected non-root UID.

Rather than create it here, we can just mount an empty-dir volume into the container. There's already an example of that in this manifest:
andI think that should eliminate the need for running the container as root too.
