I followed below link to create strimzi cluster operator in k8s

<https://medium.com/@sincysebastian/setup-kafka-with-debezium-using-strimzi-in-kubernetes-efd494642585>

Downloaded strimzi 0.17.0 version and unzip it. I ran 
Kubectl apply -f apply install/cluster-operator . 
I am getting error "Detection of version failed" and it's socket connection timed out.

For work around I have added STRIMZI\_KUBERNETES\_VERSION in cluster-operator conf file .
Now I am getting "Detection of routes.openshift.io/ API failed . API Will be disabled". 

I thought it network policy issue and added to allow all ports. Getting same errors.
...
egress:
- {}
ingress:
- {}

Can anyone please help me out what I am missing here and how to make it strimzi with debezuim in k8s .

Thanks in advance.
