GCP Cloud SQL 未能删除实例，因为 `deletion_protection` 设置为 true [英] GCP Cloud SQL failed to delete instance because `deletion_protection` is set to true

问题描述

我有一个用于配置 Cloud SQL 实例的 tf 脚本，还有几个数据库和一个管理员用户.我已重命名该实例，因此创建了一个新实例，但 terraform 在删除旧实例时遇到了问题.

I have a tf script for provisioning a Cloud SQL instance, along with a couple of dbs and an admin user. I have renamed the instance, hence a new instance was created but terraform is encountering issues when it comes to deleting the old one.

Error: Error, failed to delete instance because deletion_protection is set to true. Set it to false to proceed with instance deletion

我尝试将 deletion_protection 设置为 false，但我一直收到同样的错误.有没有办法检查哪些资源需要将 deletion_protection 设置为 false 才能被删除?我只是将它添加到 google_sql_database_instance 资源中.

I have tried setting the deletion_protection to false but I keep getting the same error. Is there a way to check which resources need to have the deletion_protection set to false in order to be deleted? I have only added it to the google_sql_database_instance resource.

我的 tf 脚本:

// Provision the Cloud SQL Instance
resource "google_sql_database_instance" "instance-master" {
  name             = "instance-db-${random_id.random_suffix_id.hex}"
  region           = var.region
  database_version = "POSTGRES_12"

  project = var.project_id

  settings {
    availability_type = "REGIONAL"
    tier              = "db-f1-micro"
    activation_policy = "ALWAYS"
    disk_type         = "PD_SSD"

    ip_configuration {
      ipv4_enabled    = var.is_public ? true : false
      private_network = var.network_self_link
      require_ssl     = true

      dynamic "authorized_networks" {
        for_each = toset(var.is_public ? [1] : [])

        content {
          name  = "Public Internet"
          value = "0.0.0.0/0"
        }
      }
    }

    backup_configuration {
      enabled = true
    }

    maintenance_window {
      day  = 2
      hour = 4

      update_track = "stable"
    }

    dynamic "database_flags" {
      iterator = flag
      for_each = var.database_flags

      content {
        name  = flag.key
        value = flag.value
      }
    }

    user_labels = var.default_labels
  }

  deletion_protection = false
  depends_on          = [google_service_networking_connection.cloudsql-peering-connection, google_project_service.enable-sqladmin-api]
}

// Provision the databases
resource "google_sql_database" "db" {
  name     = "orders-placement"
  instance = google_sql_database_instance.instance-master.name
  project  = var.project_id
}

// Provision a super user
resource "google_sql_user" "admin-user" {
  name     = "admin-user"
  instance = google_sql_database_instance.instance-master.name
  password = random_password.user-password.result
  project  = var.project_id
}

// Get latest CA certificate
locals {
  furthest_expiration_time = reverse(sort([for k, v in google_sql_database_instance.instance-master.server_ca_cert : v.expiration_time]))[0]
  latest_ca_cert           = [for v in google_sql_database_instance.instance-master.server_ca_cert : v.cert if v.expiration_time == local.furthest_expiration_time]
}

// Get SSL certificate
resource "google_sql_ssl_cert" "client_cert" {
  common_name = "instance-master-client"
  instance    = google_sql_database_instance.instance-master.name
}

推荐答案

好像你的代码要重新创建这个 sql 实例.但是您当前的 tfstate 文件包含 deletion_protection 参数的 true 值的实例代码.在这种情况下，您首先需要在 tfstate 文件中手动将此参数的值更改为 false 或在运行 terraform apply 的代码中添加 deletion_protection = true 之后的命令(注意:您的代码不应该重新创建实例).在这些操作之后，你可以对你的 SQL 实例做任何事情

Seems like your code going to recreate this sql-instance. But your current tfstate file contains an instance-code with true value for deletion_protection parameter. In this case, you need first of all change value of this parameter to false manually in tfstate file or by adding deletion_protection = true in the code with running terraform apply command after that (beware: your code shouldn't do a recreation of the instance). And after this manipulations, you can do anything with your SQL instance
