Expected results:

The error message above should better identify what the problem is.  This may just be expected if the pod has not yet started, or we should be shouting more clearly that there is a networking problem if something unrecoverable happened.

The problem is that the "Missing CNI default network" is expected when a node starts and pods are started before the networking is ready.  But the above message looks a bit different and may be a separate problem.  If it is, we need to make it clear what to look at.

Additional info:

Comment 1 Douglas Smith 2020-05-05 19:47:29 UTC
I believe this is actually a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1777040 -- which handles up dating the "Missing CNI default network" language.

Comment 2 Alexander Constantinescu 2020-05-07 14:53:49 UTC

This bug has no update since a couple of months, what is the impact of this? Can we close it?

1) That "Missing CNI default network might have dissapeared since"
2) If #comment 1 is true, then this should be closed.
