Lab 2.3: Confusion regarding NodePort service and Cluster IP
Although I'm able to complete Lab 2.3 - "Create a basic Pod", I am a bit confused about how the NodePort service works. After creating a service of type "NodePort":
- How come the "EXTERNAL-IP" Column of the service "basicservice" is "none", instead of the Node IP?
- I could query the nginx app through both the master-node IP AND the worker-node IP. I thought the pod is assigned to one of the nodes, so how come it is accessible through the external IP of either node?
- When people say "External Cluster IP", do they just mean one of the Node's IPs?
