livez and healthz are slightly different, but in our configuration the distinction isn't meaningful enough to backport (I don't think). huh, I can't seem to set targets. fun. Verified in 4.8.0-0.nightly-2021-04-06-162113: $ oc get po -n openshift-kube-apiserver kube-apiserver-ci-ln-qfw7ms2-002ac-p5jzx-master-0 -o yaml ... livenessProbe: failureThreshold: 3 httpGet: path: livez ... readinessProbe: failureThreshold: 3 httpGet: path: readyz ... Liveness probe now uses "livez". Run crictl stop with the kube-apiserver container on master, then: $ oc describe po -n openshift-kube-apiserver kube-apiserver-ci-ln-qfw7ms2-002ac-p5jzx-master-0 ... Warning Unhealthy 6m14s (x2 over 6m24s) kubelet Liveness probe failed: Get "https://10.0.0.6:6443/livez": dial tcp 10.0.0.6:6443: connect: connection refused Warning ProbeError 6m14s (x2 over 6m24s) kubelet Readiness probe error: Get "https://10.0.0.6:6443/readyz": dial tcp 10.0.0.6:6443: connect: connection refused ... Same, liveness probe now uses "livez". Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
