HI,
I have a container with port 25.
Port Name Publish the container port Protocol As a On listening port
http 25 TCP ClusterIP Same as container port
The Service is exposed via a NodePort
Port Name Publish the service port Protocol Target Port Node Port
http 25 TCP 25 30840
and the container is full of logs like this:
