How can you handle and troubleshoot issues related to Amazon Machine Images (AMIs) such as image corruption or launch failure?
To handle and troubleshoot issues related to AMIs, follow these steps:
1. Verify the status of the instance: Check if it’s in a running state or stuck during launch.
2. Review logs: Examine CloudWatch Logs, EC2 console logs, and application logs for error messages or warnings.
3. Validate permissions: Ensure your IAM role has necessary permissions to access resources like EBS volumes or S3 buckets.
4. Test with another AMI: Launch an instance using a different, known-working AMI to isolate the issue.
5. Inspect image contents: Use AWS CLI commands (e.g., “aws ec2 describe-images”) to check for inconsistencies or corruption.
6. Re-create the AMI: If possible, create a new AMI from the source instance or snapshot to rule out corruption.
7. Contact AWS Support: If all else fails, reach out to AWS Support for further assistance.
