Description Junqi Zhao 2018-05-08 08:48:32 UTC

Description of problem:
This defect is split from https://bugzilla.redhat.com/show_bug.cgi?id=1561196#c15

Deploy logging firstly and change fluentd nodeSelector to non-default value, logging-infra-test-fluentd=true

# oc get ds
NAME              DESIRED   CURRENT   READY     UP-TO-DATE   AVAILABLE   NODE SELECTOR                     AGE
logging-fluentd   2         2         2         2            2           logging-infra-test-fluentd=true   10m

Update logging with the same inventory, fluentd nodeSelector would always use the default nodeSelector logging-infra-fluentd=true, not get the existing nodeSelector from environment

# oc get ds
NAME              DESIRED   CURRENT   READY     UP-TO-DATE   AVAILABLE   NODE SELECTOR                AGE
logging-fluentd   2         2         2         2            2           logging-infra-fluentd=true   15m

Tested with openshift-ansible-3.10.0-0.47.0.git.0.c018c8f.el7.noarch
existing nodeselectors for fluentd could be used when update logging
