/*
|
||
|
|
This test verifies that even if we use flannel-backend=none, kube-api starts correctly so that it can
|
||
|
|
accept the custom CNI plugin manifest. We want to catch regressions in which kube-api is unresponsive.
|
||
|
|
To do so we check for 25s that we can consistently query kube-api. We check that pods are in pending
|
||
|
|
state, which is what should happen if there is no cni plugin
