The CodeDeploy agent’s log file contains the following error message:InvalidSignatureException Signature expired: |time| is now earlier than |time|What is the underlying cause of this issue?
The development team signed the CodeDeploy revision after the team created the deployment.
The development team signed the CodeDeploy revision with a key that was not valid.
The deployment did not finish within the specified time frame.
The date setting or the time setting on the EC2 instance is not correct.
Explanations:
Signing the CodeDeploy revision after creating the deployment would not result in an “InvalidSignatureException” with a time mismatch.
Signing the revision with an invalid key would cause an authentication error, not a signature expiry due to time.
While deployments can fail due to timeouts, the error message specifically mentions an issue with signature expiration due to time, not the overall deployment time.
The error message indicates that the system is comparing timestamps, suggesting that the time on the EC2 instance is incorrect or out of sync, leading to an expired signature.
I arrange that the answer is:
The date setting or the time setting on the EC2 instance is not correct.
