easy📝 Configuration Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Check HTTP GET probe syntax
The correct syntax useshttpGetwithpathstarting with a slash andportas a number.Step 2: Validate each option
livenessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 5 periodSeconds: 10 correctly uses/healthand port 8080. livenessProbe: exec: command: ["curl", "/health"] initialDelaySeconds: 5 periodSeconds: 10 uses exec with curl incorrectly. livenessProbe: tcpSocket: port: 8080 initialDelaySeconds: 5 periodSeconds: 10 uses tcpSocket which is different. livenessProbe: httpGet: path: health port: 8080 initialDelaySeconds: 5 periodSeconds: 10 misses the leading slash in path.Final Answer:
livenessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 5 periodSeconds: 10 -> Option DQuick Check:
HTTP GET probe with correct path and port = livenessProbe: httpGet: path: /health port: 8080 initialDelaySeconds: 5 periodSeconds: 10 [OK]
Quick Trick: HTTP path must start with '/' and port is a number [OK]
Common Mistakes:
- Missing leading slash in path
- Using exec command incorrectly
- Confusing tcpSocket with httpGet
