From c1cd512cb824c4c470efe7660c91ffeda62327bc Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Wed, 20 Jan 2021 22:24:20 +0100 Subject: Use random network names in the e2e tests Unlike the container storage all e2e test are using the same cni config directory. This causes problems if the network name already exists. Using random names will make the second run pass even if the first failed. This is only done to prevent full CI failures.
