Description Cuiping HUO 2020-02-21 10:56:50 UTC
Description of problem:
Now, OCP supports the Windows worker. But, the tsb operator doesn't. 
So, we should set the `NodeSelector` in their deployment field of CSV to avoid the failure on the Windows worker.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install OCP with a Windows worker.

$ oc get nodes --show-labels |grep windows
ip-10-0-38-164.us-east-2.compute.internal    Ready                      worker   6h52m   v1.16.2   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/instance-type=m5a.large,beta.kubernetes.io/os=windows,failure-domain.beta.kubernetes.io/region=us-east-2,failure-domain.beta.kubernetes.io/zone=us-east-2c,kubernetes.io/arch=amd64,kubernetes.io/hostname=ec2amaz-ldli9dr,kubernetes.io/os=windows,node-role.kubernetes.io/worker=,node.openshift.io/os_id=Windows

2. Install a tsb operator and check its deployment. 

Actual results:
There is no "NodeSelector" specific in the Deployment field of their CSV.

$ oc get csv -n openshift-template-service-broker openshifttemplateservicebrokeroperator.4.4.0-202002111717 -o yaml| grep -i "NodeSelector"

Expected results:
In order to run failure on the Windows worker. We should set the "NodeSelector" to select the Linus worker in the Deployment field of their CSV. For example:
$ oc get deployment -n openshift-marketplace certified-operators -o yaml | grep -i "NodeSelector" -A 1
        beta.kubernetes.io/os: linux
