AWS S3 Lifecycle Rules Not Transitioning into Glacier, not sure what the issue is?-CodePudding

I have this CFT that creates a S3 bucket with lifecycle rule to transition into Glacier immediately but it's not working they are still in standard after a couple of days. Any help would be appreciated thanks.

S3 lifecycle transitions have minimum age rules which needs to be true for each object. You can't immediately move a file directly to glacier after uploading it in S3.

Generic lifecycle policy could be S3 (standard) -> 30days -> S3 (Infrequent Access) -> 60days -> Glacier

Check the details on the minimum number of days from the documentation.

Works! It's not an exact time but it works, the change runs once a day, so updating CFTs may delaying the change taking place for a day or so.
