What is the first step to verify if a Kubernetes service is reachable from a pod?
ACheck the pod's logs for errors
BRestart the Kubernetes cluster
CPing the service IP from the pod
DVerify the service's endpoints exist
Step-by-Step Solution
Solution:

  1. Step 1: Check service endpoints

    Endpoints show which pods the service routes to. Without endpoints, service is unreachable.

  2. Step 2: Confirm connectivity after endpoints exist

    Once endpoints are verified, test connectivity from pod to service IP.

  3. Final Answer:

    Verify the service's endpoints exist -> Option D

  4. Quick Check:

    Service endpoints = connectivity check [OK]
Quick Trick: Always check endpoints before testing service connectivity [OK]
Common Mistakes:
  • Trying to ping service IP before confirming endpoints
  • Ignoring endpoints and checking pod logs first
  • Restarting cluster unnecessarily
