Kubernetes - Labels and Selectors

Given pods with labels:
pod1: app=web, env=prod
pod2: app=api, env=prod
pod3: app=web, env=dev
What pods are selected by app in (web) , env=prod?

Apod2 only

Bpod1 and pod3

Cpod2 and pod3

Dpod1 only

Step-by-Step Solution

Solution:

Step 1: Analyze label selector conditions
The selector requires app label to be 'web' and env label to be 'prod'.
Step 2: Check pods against conditions
pod1 has app=web and env=prod, so it matches. pod3 has app=web but env=dev, so no. pod2 has env=prod but app=api, so no.
Final Answer:
pod1 only -> Option D
Quick Check:
Both conditions must match = pod1 only [OK]

Quick Trick: Multiple selectors combine with AND logic [OK]

Common Mistakes:

Assuming OR logic between selectors
Ignoring one of the label conditions
Misreading label values
