Kubernetes - Labels and Selectors

Given this pod YAML snippet, what will be the output of kubectl get pods -l app.kubernetes.io/instance=webapp if the pod has these labels?

metadata:
  labels:
    app.kubernetes.io/name: myapp
    app.kubernetes.io/instance: webapp
    app.kubernetes.io/version: v1

ANo pods will be listed because the name label does not match

BAn error will occur due to invalid label selector syntax

CThe pod will be listed because it matches the instance label

DAll pods with any app.kubernetes.io label will be listed

Step-by-Step Solution

Solution:

Step 1: Understand label selector behavior
The command filters pods by label key and value. It lists pods where app.kubernetes.io/instance equals webapp.
Step 2: Check pod labels against selector
The pod has app.kubernetes.io/instance: webapp, so it matches and will be listed.
Final Answer:
The pod will be listed because it matches the instance label -> Option C
Quick Check:
Label selector matches pod = Pod listed [OK]

Quick Trick: Label selector matches exact key-value pairs [OK]
