From f230214db120793d68d95c5b1892ca5d7d128e79 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Tue, 6 Apr 2021 23:39:09 +0200 Subject: rootless cni add /usr/sbin to PATH if not present The CNI plugins need access to iptables in $PATH. On debian /usr/sbin is not added to $PATH for rootless users. This will break rootless cni completely. To prevent breaking existing users add /usr/sbin to $PATH in podman if needed.
