Description Stefan Schimanski 2019-04-17 12:54:47 UTC 
Description of problem:

In CI we occasionally see connection refused when connecting through the NLB to the kube-apiserver. With /readyz used as NLB target health check and our timing (35 sec kube-apiserver minimum-termination-period, 3*10 sec NLN target unhealthz threshold) this should never happen.

Version-Release number of selected component (if applicable):

4.10

How reproducible:

Randomly in CI.
