From 9d818be7329929b05b93e432c408ee65726ec2c0 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Sun, 21 Feb 2021 16:27:25 +0100 Subject: Fix podman network IDs handling The libpod network logic knows about networks IDs but OCICNI does not. We cannot pass the network ID to OCICNI. Instead we need to make sure we only use network names internally. This is also important for libpod since we also only store the network names in the state. If we would add a ID there the same networks could accidentally be added twice.
