Description Nikolaos Leandros Moraitis 2020-07-23 10:06:37 UTC 
test:
[sig-arch][Early] Managed cluster should start all core operators 

is failing frequently in CI, see search results:
https://search.svc.ci.openshift.org/?maxAge=168h&context=1&type=bug%2Bjunit&name=&maxMatches=5&maxBytes=20971520&groupBy=job&search=%5C%5Bsig-arch%5C%5D%5C%5BEarly%5C%5D+Managed+cluster+should+start+all+core+operators


FIXME: Replace this paragraph with a particular job URI from the search results to ground discussion.  A given test may fail for several reasons, and this bug should be scoped to one of those reasons.  Ideally you'd pick a job showing the most-common reason, but since that's hard to determine, you may also chose to pick a job at random.  Release-gating jobs (release-openshift-...) should be preferred over presubmits (pull-ci-...) because they are closer to the released product and less likely to have in-flight code changes that complicate analysis.

FIXME: Provide a snippet of the test failure or error from the job log
Comment 1 W. Trevor King 2020-07-24 04:52:42 UTC 
Picking an example job, here's 4.6.0-0.ci-2020-07-21-114552 [1]:

fail [github.com/openshift/origin@/test/extended/operators/operators.go:94]: Jul 23 14:54:30.357: Some cluster operators are not ready: ingress (Degraded=True IngressControllersDegraded: Some ingresscontrollers are degraded: default)

From the must-gather [2]:

Also "[sig-arch]" != Multi-Arch component (that's about s390x, etc.).  sig-arch is about OpenShift/Kube architecture, while Multi-Arch is about CPU architecture.  Moving to Routing for the ingress issue.

Note for the routing folks: "Some ingresscontrollers are degraded: default" does not make the next step:

  $ oc -n openshift-ingress-operator get -o yaml dnsrecords default-wildcard

(which presumably also has a web-console analog) very clear.  It would be nice if we either gave a more-direct pointer in the ClusterOperator condition and/or bubbled some portion of the error up into the condition message.

Comment 2 Andrew McDermott 2020-07-24 17:34:55 UTC 
I’m adding UpcomingSprint, because I was occupied by fixing bugs with
higher priority/severity, developing new features with higher
priority, or developing new features to improve stability at a macro
level. I will revisit this bug next sprint.
Comment 3 mfisher 2020-08-18 20:01:45 UTC 
Target reset from 4.6 to 4.7 while investigation is either ongoing or not yet started.  Will be considered for earlier release versions when diagnosed and resolved.
Comment 4 Russell Teague 2020-08-31 15:16:41 UTC 
I'm seeing the same test fail regularly, but with a different failure mode occasionally.  Should I open a different bug for this?

Comment 5 Russell Teague 2020-08-31 20:54:09 UTC 
Looking at the last 24 hours of failures, the test failed on the dns operator 2 times and the ingress operator 5 times.

Comment 8 Andrew McDermott 2020-10-02 17:37:40 UTC 
Tagging with UpcomingSprint while investigation is either ongoing or
pending. Will be considered for earlier release versions when
diagnosed and resolved.
