Kubernetes - Services

Given this NodePort service YAML, what port will you use to access the app externally?

apiVersion: v1
kind: Service
metadata:
  name: example-service
spec:
  type: NodePort
  selector:
    app: example
  ports:
    - port: 80
      targetPort: 8080
      nodePort: 31000

APort 31000 on the node IP

BPort 80 on the node IP

CPort 8080 on the node IP

DPort 80 on the pod IP

Step-by-Step Solution

Solution:

Step 1: Understand NodePort port usage
The nodePort field defines the port exposed on each node's IP for external access.
Step 2: Identify the correct port from YAML
The YAML sets nodePort: 31000, so external access uses port 31000 on any node IP.
Final Answer:
Port 31000 on the node IP -> Option A
Quick Check:
External access uses nodePort value = 31000 [OK]

Quick Trick: Use the nodePort value to access service externally [OK]

Common Mistakes:

Using targetPort or port instead of nodePort externally
Trying to access pod IP directly
Confusing port and nodePort fields
