Description Nicholas Schuetz 2018-04-11 12:01:23 UTC 
The service catalog apiserver and controller are deployed as daemonsets to the first master only.

An HA mode cluster will be crippled if you shutdown the master which has these daemonsets deployed.  IMHO, we should do one of two things:

1)  make them normal pods so they can be migrated in cases of failure
or
2)  deploy the daemonset to each master (instead of only master01).


[root@master01 ~]# oc get pods --all-namespaces -owide |grep catalog
kube-service-catalog                apiserver-jcb4w                               1/1       Running     1          22h       10.129.0.16   master01.ocp.nicknach.net
kube-service-catalog                controller-manager-9pwg7                      1/1       Running     2          22h       10.129.0.18   master01.ocp.nicknach.net

one hour later, after shutting down master01:

[root@master02 ~]# oc get pods --all-namespaces -owide |grep catalog
kube-service-catalog                apiserver-jcb4w                               1/1       NodeLost    1          23h       10.129.0.16   master01.ocp.nicknach.net
kube-service-catalog                controller-manager-9pwg7                      1/1       NodeLost    2          23h       10.129.0.18   master01.ocp.nicknach.net
