Description gaoshang 2019-11-15 06:34:17 UTC
Description of problem:
After added a windows worker to OCP 4.2 GA cluster, openshift-marketplace was trying to create pod on windows worker and failed, this should be avoided.

Version-Release number of selected component (if applicable):
OCP 4.2 GA
# oc get clusterversion
version   4.2.0     True        False         27h     Cluster version is 4.2.0

How reproducible:

Steps to Reproduce:
1. Install OCP 4.2 GA and add windows worker
2. Delete redhat-operators pod in openshift-marketplace(maybe more than once)
# oc delete pod redhat-operators-5d878dc498-c74s4 -n openshift-marketplace
pod "redhat-operators-5d878dc498-c74s4" deleted
3. Check redhat-operators pod was trying to create in windows worker and failed
# oc get pod -n openshift-marketplace
NAME                                    READY   STATUS              RESTARTS   AGE
certified-operators-6b5c9d69b8-mftww    1/1     Running             0          27h
community-operators-8b5c5bf9-fvww6      1/1     Running             0          27h
marketplace-operator-5c846b89cb-c79qs   1/1     Running             0          27h
redhat-operators-547f57b5b8-vfddz       1/1     Running             0          27h
redhat-operators-5d878dc498-kxvjv       0/1     ContainerCreating   0          123m
4. Check redhat-operators deployment, NodeSelector is not specified
# oc edit deployment.apps/redhat-operators

Actual results:
redhat-operators pod was trying to create in windows worker and failed.

Expected results:
Avoid creating pod on windows worker for openshift-marketplace.

Additional info:
This can be accomplished by adding a NodeSelector to all builds:
kubernetes.io/os: linux
Details please see: https://jira.coreos.com/browse/DEVEXP-341

cv: 4.2.0-0.nightly-2019-12-19-211218

test result:
1. the spec of nodeSelector of opsrc deployment:     
        beta.kubernetes.io/os: linux
2. delete the pods of opsrc the new pod won't be scheduled to the windows nodes.
