Feature: Static IP with "podman play kube --network=<network> --ip=<IP>"

[hoonetorg]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description

It would be useful if podman play kube would support using static IP for the generated pod.
The usecase for me is a dhcphelper pod which uses the host network wants to talk to a app pod, which has dnsmasq running in it. Forwarding DHCP requests from dhcphelper pod to app pod with dnsmasq container is easy by using a static IP.

Steps to reproduce the issue:

1. podman play kube app.yaml --network=app --ip=192.168.2.253

Describe the results you received:

Error: unknown flag: --ip

Describe the results you expected:

Pod:
553d4b...
Containers:
xda643...
381d9f...
y1c49f...
