Kubernetes - Health Checks and Probes

AstartupProbe: exec: command: ["/bin/check-startup.sh"] periodSeconds: 3 failureThreshold: 10

BstartupProbe: httpGet: path: /start port: 80 periodSeconds: 10 failureThreshold: 3

CstartupProbe: tcpSocket: port: 8080 periodSeconds: 3 failureThreshold: 5

DstartupProbe: exec: command: ["/bin/check.sh"] periodSeconds: 10 failureThreshold: 3

Step-by-Step Solution

Solution:

Step 1: Match periodSeconds and failureThreshold requirements
We want periodSeconds=3 and failureThreshold=10, so probe runs every 3 seconds and allows 10 failures.
Step 2: Check probe type and command
startupProbe: exec: command: ["/bin/check-startup.sh"] periodSeconds: 3 failureThreshold: 10 uses exec with correct command and matches timing requirements exactly.
Final Answer:
Option A matches the required startupProbe configuration -> Option A
Quick Check:
periodSeconds=3 and failureThreshold=10 in exec probe = correct [OK]

Quick Trick: Match periodSeconds and failureThreshold to desired timing [OK]
