Description

EFS now allows for setting life cycle / IA configuration for saving costs on infrequently accessed data. This seems to be for new EFS filesystems only though.

Please have terraform efs resource to leverage and enable this configuration

New or Affected Resource(s)

• aws_efs_*

It appears this should be implemented via a new lifecycle_policy configuration block in aws_efs_file_system, e.g.

# Potential Terraform configuration, details may change during development
resource "aws_efs_file_system" "example" {
  # ... other configuration ...
  lifecycle_policy {
    transition_to_ia = "AFTER_30_DAYS"
  }
}

this would be an AWS specific question I guess. In the event that terraform resource is updated with the new lifecycle policy change, can I make changes to an existing EFS filesystem using this change in the resource block?

hi @bflad just checking for your suggestions on this

[tdmalone]

can I make changes to an existing EFS filesystem using this change in the resource block?

~According to the docs, only if you created your file system after 13th Feb this year.~

EDIT: As of 9th July, the above is no longer the case:

Additionally, you can now enable Lifecycle Management for all EFS file systems.

@bflad anybody working this issue to your knowledge? Was thinking of knocking it out.

Additional lifecycle policies announced.
Requires:

• https://github.com/terraform-providers/terraform-provider-aws/pull/9287

[tdmalone]

^ And the above announcement also releases IA to _existing_ file systems created before the previous 13th Feb cutoff. 🎉

[ryno75]

@ewbankkit do you think it would be best to include the SDK version bump and new lifecycles as part of my PR (#9250)?

[ewbankkit]

@ryno75 Yes it looks like you should git rebase onto the upstream master to address some of the changes that @bflad suggested.

Support for a new lifecycle_policy configuration block has been merged and will release with version 2.23.0 of the Terraform AWS Provider, in the next day or two. Thanks to @ryno75 for the implementation. 👍
