Description Jan Chaloupka 2021-01-26 12:41:49 UTC
"ss" shows sockets in CLOSE-WAIT state, so it's more accurate.

Verified bug in the payload below and i see that changes present in the PR are present.

[knarra@knarra ~]$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.7.0-0.nightly-2021-01-27-022930   True        False         175m    Cluster version is 4.7.0-0.nightly-2021-01-27-022930

Before the fix:
[knarra@knarra ~]$ oc get pod openshift-kube-scheduler-wduan-0126b-xtdcv-control-plane-0 -o yaml -n openshift-kube-scheduler | grep 10251
        port: 10251
        port: 10251
      echo -n "Waiting for port :10259 and :10251 to be released."
      while [ -n "$(lsof -ni :10251)" -o -n "$(lsof -i :10259)" ]; do

After the fix:
[knarra@knarra ~]$ oc get pod openshift-kube-scheduler-ip-10-0-147-38.us-east-2.compute.internal -o yaml -n openshift-kube-scheduler | grep 10251
      echo -n "Waiting for port :10259 and :10251 to be released."
      while [ -n "$(ss -Htan '( sport = 10251 or sport = 10259 )')" ]; do

Based on the above moving bug to verified state.
