Terraform cloud_sql_instance“connection_name”字段无法设置

Question

我正在尝试使用 Terraform 创建一个谷歌云 sql 实例。在google_sql_database_instance 资源下定义connection_name 参数时，我在运行terraform apply 时收到以下错误：

Error: google_sql_database_instance.sql_instance: "connection_name": this field cannot be set

我的 Terraform 块：

resource "google_sql_database_instance" "sql_instance" {
  name             = "${var.sql_name}"
  region           = "${var.region}"
  database_version = "POSTGRES_9_6"
  connection_name  = "${data.google_project.my_project.project_id}:${var.region}:${var.sql_name}"
  project          = "${data.google_project.my_project.project_id}"

  settings {
    tier      = "db-custom-6-23040"
    disk_size = "${var.sql_disk_size}"
    disk_type = "${var.sql_disk_type}"
  }
}

删除connection_name 参数会导致plan 成功，从值中删除所有: 以及对字符串进行硬编码也会导致失败。

google_sql_database_instance 的 connection_name 参数仅用于读取，而不是由用户设置。

因此，您不应该尝试设置它，而是仅在将输出传递给另一个资源或像这样的输出时才需要它：

resource "google_sql_database_instance" "sql_instance" {
  name             = "${var.sql_name}"
  region           = "${var.region}"
  database_version = "POSTGRES_9_6"
  project          = "${data.google_project.my_project.project_id}"

  settings {
    tier      = "db-custom-6-23040"
    disk_size = "${var.sql_disk_size}"
    disk_type = "${var.sql_disk_type}"
  }
}

output "connection_name" {
  value = "${google_sql_database_instance.sql_instance.connection_name}"
}
