From d7292dbf2731701c122656400ce5007693efe3c8 Mon Sep 17 00:00:00 2001

Subject: add --ip to podman play kube

Add a new --ip flag to podman play kube. This is used to specify a
static IP address which should be used for the pod. This option can be
specified several times because play kube can create more than one pod.

Fixes #8442
