[karpenter] enable ability to import existing eventbridge rules

[k24dizzle]

Since there isn't a way to specify the name of these rules:

resource "aws_cloudwatch_event_rule" "this" {
  for_each = { for k, v in local.events : k => v if local.enable_spot_termination }

  name_prefix   = "${var.rule_name_prefix}${each.value.name}-"
  description   = each.value.description
  event_pattern = jsonencode(each.value.event_pattern)

  tags = merge(
    { "ClusterName" : var.cluster_name },
    var.tags,
  )
}

(only the name_prefix), it isn't easy to import these rules.

Is it ok having multiple duplicate eventbridge rules that route to the karpenter sqs interruption queue? Will karpenter be able to deduplicate them?

Are those for the same cluster or different clusters? Why so many copies of rules?

same cluster, I kept deleting my terraform state file so that's why it continued to make copies

[bryantbiggs]

I would just delete all of the rules manually and re-apply and that should leave just one set of the rules

closing since this isn't a module relate issue
