Starting from September 19, 2023, build image CloudFormation stack ends in DELETE_FAILED status after the image is successfully built. The failures in the stack events look like:
| Timestamp | Logical ID | Status | Status reason |
|---|---|---|---|
| 2023-12-01 06:00:20 UTC-0800 | aws-parallelcluster-3-7-2-amzn2-hvm-arm64-202312011211 | DELETE_FAILED | The following resource(s) failed to delete: [DeleteStackFunctionExecutionRole]. |
| 2023-12-01 06:00:19 UTC-0800 | DeleteStackFunctionExecutionRole | DELETE_FAILED | Internal Failure |
The image is built correctly despite the stack is in DELETE_FAILED and you can use it as custom AMI for cluster creation.
ParallelCluster versions 3.0.0+ are affected.
To delete the stack in DELETE_FAILED status, users can manually delete it on AWS CloudFormation web console or using AWS CLI.
To fix stack self-deletion for future build-image process, specify a custom IAM role using CleanupLambdaRole parameter in build image configuration files. The custom IAM role should contain policies described here.
