Kubernetes - Health Checks and Probes

You want to configure a Kubernetes HTTP readiness probe that waits 15 seconds after container start, then checks the path /health every 3 seconds, but fails the pod if no response within 1 second. Which is the correct probe configuration snippet?

AreadinessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 15 periodSeconds: 3 timeoutSeconds: 1

BreadinessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 3 periodSeconds: 15 timeoutSeconds: 1

CreadinessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 15 periodSeconds: 1 timeoutSeconds: 3

DreadinessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 1 periodSeconds: 15 timeoutSeconds: 3

Step-by-Step Solution

Solution:

Step 1: Match initialDelaySeconds to 15 seconds
The probe must wait 15 seconds before first check, so initialDelaySeconds: 15.
Step 2: Set periodSeconds to 3 seconds and timeoutSeconds to 1 second
Checks happen every 3 seconds, and timeout is 1 second as required.
Final Answer:
Correct probe with initialDelaySeconds 15, periodSeconds 3, timeoutSeconds 1 -> Option A
Quick Check:
initialDelay=15, period=3, timeout=1 matches requirements [OK]

Quick Trick: Match timing values exactly to requirements [OK]

Common Mistakes:

Swapping initialDelaySeconds and periodSeconds
Setting timeoutSeconds longer than periodSeconds
Using wrong path or port
