Description Clayton Coleman 2019-05-19 16:04:09 UTC

This looks like a skew bug between master and kubelet, so we need to treat it special

Post rebase 

 Probing container should *not* be restarted with a non-local redirect http liveness probe [Suite:openshift/conformance/parallel] [Suite:k8s] 4m24s

flakes heavily when masters are 4.2 and rhcos is 4.1 kubelet.  This is not a new test so my assumption is something is broken between 1.13 kubelet and 1.14 masters that we need to know about

fail [k8s.io/kubernetes/test/e2e/common/container_probe.go:524]: May 18 23:26:13.408: pod container-probe-1387/liveness-http-redirect - expected number of restarts: 0, found restarts: 6

This blocks upgrade to 4.2

Comment 1 Clayton Coleman 2019-05-19 16:06:57 UTC

This bug may not be deferred from 4.2 without identifying why this fails.  Disabled in https://github.com/openshift/origin/pull/22865

Comment 3 Seth Jennings 2019-07-23 17:20:23 UTC

This test was new in kubernetes 1.14 and does not tolerate skew between the e2e from 4.2 and kubelet running at 4.1
