h1. Bug report

 I deployed Debezium according to this link:
[https://debezium.io/documentation/reference/3.0/operations/kubernetes.html]

I'm having a problem. I need to be in the debezium-connect-cluster-connect pod to get the connector status. I created a service of type NodePort, but I'm failing to get the connector status.

I checked the Debezium configuration and found that the following settings might be limiting:
[rest.advertised.host.name|http://rest.advertised.host.name/] = 10.233.111.78
rest.advertised.port = 8083

 

I want to change [rest.advertised.host.name|http://rest.advertised.host.name/] to 10.168.2.187 (the IP address of the k8s node) and rest.advertised.port to 32003 (the node port). 

I tried changing the configuration in the image, but it didn't work.

Debezium connector configuration file:

rest.advertised.host.name=10.233.111.78
rest.advertised.port=8083
h2. Do you see the same behaviour using the latest released Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)

yes
