This might be tightly related to wrong UPI setup, compare https://github.com/openshift/openshift-docs/pull/21336#issuecomment-651635804. We don't own the load balancer setup in UPI and EOFs are very probably caused by that. The load balancer is wrongly configured. With tcp probe we get this output. Use proper HTTPS probes on /readyz and it goes away. The docs for IPI were wrong for quite some time. I believe they finally got fixed by describing how to set up probes.

Moving this to docs team so that they can include information on the kube-apiserver health checks setup for UPI. the installer doc added by apiserver team is here https://github.com/openshift/installer/blob/master/docs/dev/kube-apiserver-health-check.md looking at https://github.com/openshift/openshift-docs/blob/main/modules/installation-load-balancing-user-infra.adoc it seems to satisfy the requirements to match the contents from https://github.com/openshift/installer/blob/master/docs/dev/kube-apiserver-health-check.md into a openshift docs page. @sttts do you agree ? Yes, they look good. Closing this bug since it is not valid anymore. |
