From f441190d10ca3d41e01a076e4b9b3a63746888b6 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Thu, 19 Nov 2020 12:34:00 +0100 Subject: Allow multiple --network flags for podman run/create We allow a container to be connected to several cni networks but only if they are listed comma sperated. This is not intuitive for users especially since the flag parsing allows multiple string flags but only would take the last value. see: spf13/pflag#72 Also get rid of the extra parsing logic for pods. The invalid options are already handled by `pkg/specgen`. A test is added to prevent a future regression.
