Terraform如何为资源修改arn？

Question

我使用数据获取集群的快照。

data "aws_db_cluster_snapshot" "db" {
  for_each               = toset(var.rds_sources)
  db_cluster_identifier  = each.key
  most_recent            = true
}

我用它就像:-

jsonencode(values(data.aws_db_cluster_snapshot.db)[*].db_cluster_snapshot_arn)

并以下列格式返回快照：

arn:aws:rds:us-west-2:916533587194:cluster-snapshot:rds:new-test-db-2022-09-12-08-05

如何将arn修改为下列格式：

arn:aws:rds:us-west-2:916533587194:cluster-snapshot:rds:new-test-db*

Answer 1

使用替换和regex模式：

replace(jsonencode(values(data.aws_db_cluster_snapshot.db)[*].db_cluster_snapshot_arn),"/-\d{4}-\d{2}-\d{2}-\d{2}-\d{2}$/","*")
