Description

Currently, the aws_db_snapshot data source only supports finding snapshots by their id or their associated database id.

These options will not work for the use-case I have. Multiple DB snapshots are created outside of my terraform config, all with a standard naming convention and set of tags. I would like to reference the latest of those.

To do that, I would like to filter based on tags (similar to the usage in aws_ami). Alternatively, my problem could also be solved by allowing for wildcards in the snapshot identifier.

New or Affected Resource(s)

• aws_db_snapshot

Potential Terraform Configuration

Here's an example of what this could look like in practice:

data "aws_db_snapshot" "latest_snapshot" {
  most_recent = true

  filter {
    name   = "name"
    values = ["postgres-backup-*"]
  }
}

Is anyone here? :)

Especially when hex values are automatically added to db snapshot identifiers, as done in the TF RDS modules, the actual name of a snapshot is unknown so any data resource request fails. The tag filter extension is highly needed.

Is there an update on this? I would love to have tags for the db snapshot identifier.

Hey guys, I have open two PRs for filtering DB snapshots by tags #31600 (db snapshots) and #31602 (cluster db snapshots - aurora). If you have any suggestion or possible improvements, please write them down :).
