Kubernetes - Health Checks and Probes

Given this pod spec snippet, what happens if the readiness probe fails?

readinessProbe:
  httpGet:
    path: /healthz
    port: 8080
  initialDelaySeconds: 5
  periodSeconds: 10

AThe pod is restarted immediately

BThe pod stops receiving new traffic but keeps running

CThe pod is deleted from the cluster

DNothing happens; the pod continues as normal

Step-by-Step Solution

Solution:

Step 1: Understand readiness probe effect
Readiness probe controls if pod is ready to get user traffic.
Step 2: Identify behavior on failure
If readiness probe fails, pod stays running but is removed from service endpoints, so no new traffic.
Final Answer:
The pod stops receiving new traffic but keeps running -> Option B
Quick Check:
Readiness failure = no traffic, pod runs [OK]

Quick Trick: Readiness failure stops traffic, no restart [OK]
