From 95633146e08aa0bc81aa3d7949c3ef02f38a2308 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Fri, 29 Apr 2022 15:01:56 +0200 Subject: libpod: host netns keep same /etc/resolv.conf When a container is run in the host network namespace we have to keep the same resolv.conf content and not use the systemd-resolve detection logic. But also make sure we still allow --dns options.
