You enabled Secrets encryption but see this error in kube-apiserver logs: failed to load encryption config: invalid key secret. What is the likely cause?
AThe encryption config file path is incorrect.
BThe encryption provider flag is missing in the manifest.
CThe kube-apiserver lacks permission to read the config file.
DThe base64-encoded secret key is invalid or malformed.
Step-by-Step Solution
Solution:
Step 1: Analyze the error message
The error says 'invalid key secret', indicating the key format is wrong.
Step 2: Understand encryption key requirements
Encryption keys must be valid base64 strings of correct length; malformed keys cause this error.
Final Answer:
The base64-encoded secret key is invalid or malformed. -> Option D
Quick Check:
Invalid key format causes 'invalid key secret' error [OK]
Quick Trick:Check base64 key format if encryption config fails. [OK]
Common Mistakes:
Assuming file path or permissions cause this specific error
Ignoring base64 encoding correctness
Forgetting key length requirements
