Terraform：根据本地值创建 tfvar

  • 772

我有一个如下的数据结构：

locals {
  replication_tasks = {
    track_to_s3_live = {
      replication_task_id       = "track-to-s3"
      migration_type            = "full-load-and-cdc"
      replication_task_settings = file("files/s3_tracking_cdc_settings.json")
      table_mappings            = file("files/s3_tracking_table_mappings.json")
      source_endpoint_key       = "source"
      target_endpoint_key       = "s3_tracking"
    }
  }
}

由此，我尝试编写等效的 .tfvars 文件（用于另一个模块）。类似于：

resource "local_file" "file" {
  content  = <<EOF
replication_tasks = "${local.replication_tasks}"
EOF
  filename = "${path.module}/tasks.auto.tfvars"
}

但是我收到此错误：

Cannot include the given value in a string template: string required.

关于如何实现这一点有什么建议吗？

    不确定你为什么要这样做，但是为了生成所需的文件，你只需序列化本地值：

    resource "local_file" "file" {
  content  = <<EOF
replication_tasks =  ${jsonencode(local.replication_tasks)}
EOF
  filename = "${path.module}/tasks.auto.tfvars"
}
