EBS Volumes not Terminating

[braden808]

I was looking at variables presented in the operator service: https://github.com/privacysandbox/coordinator-services-and-shared-libraries/blob/main/operator/terraform/aws/applications/operator-service/variables.tf and was looking for an option to Terminate EBS Volume upon shutdown of an Aggregation Service EC2 instance. I am currently running into an issue where I am hitting the EBS quoata of 50TiB in AWS. There is 6400 active volumes all using 8GiB. Delete on termination can be added to the launch template of the ASG: https://repost.aws/knowledge-center/deleteontermination-ebs.

This could be a side effect of having to kill the instances prematurely due to the enclave not spinning up properly as brought up in issue #86. Please inform me if the default behavior is the EBS volume shutting down by default.

Please let me know if I am managing my EBS volumes improperly.

Hi @braden808, if you want to delete the EBS volume when the instance terminates, you can edit the launch template and set the EBS delete_on_termination parameter to True.

Note that changes to the launch template would be overwritten after an upgrade. Let us know if this would be a major issue for you going forward.

Hello @nlrussell, if it would be ideal to have it set in the terraform environment, that way I do not need to to worry about the reset when updating the aggregation service. I am spinning up thousands of Aggregation Service jobs so I do reach the EBS volumes service quota limits quickly. Is there a way I can put an official feature request?
