使用 Terraform 的过程是围绕 main.tf 文件进行，通过在 main.tf 文件中追加相应的内容实现资源的管理与编排。本文以创建云数据库 MySQL 版实例为例进行说明。

操作步骤

以创建云数据库 MySQL 版实例为例，追加以下内容到 main.tf 文件，参数内容需要自行修改，其中 my-instance-0 表示资源名字。

resource "volcengine_rds_instance_v2" "my-instance-0" {
  db_engine_version = "MySQL_5_7"
  instance_type     = "HA"
  node_info {
    node_type = "Primary"
    node_spec = "rds.mysql.1c2g"
    zone_id   = "cn-beijing-a"
  }
  node_info {
    node_type = "Secondary"
    node_spec = "rds.mysql.1c2g"
    zone_id   = "cn-beijing-a"
  }
  storage_type           = "LocalSSD"
  storage_space          = 100
  vpc_id                 = "vpc-xxx"
  subnet_id              = "subnet-xxx"
  charge_info {
    charge_type = "PostPaid"
  }
}

进入 main.tf 所在目录，在终端执行以下命令，查看执行计划。 terraform plan 执行后，在终端中会显示待创建实例的相关信息，示例如下。

# volcengine_rds_instance_v2.my-instance-0 will be created
+ resource "volcengine_rds_instance_v2" "my-instance-0" {
    + connection_info   = (known after apply)
    + db_engine_version = "MySQL_5_7"
    + id                = (known after apply)
    + instance_type     = "HA"
    + storage_space     = 100
    + storage_type      = "LocalSSD"
    + subnet_id         = "subnet-rrzzs6dzof0gv0x58bh****"
    + vpc_id            = "vpc-13g2qkkzntfy83n6nu4z1****"

    + charge_info {
        + auto_renew  = (known after apply)
        + charge_type = "PostPaid"
        + period      = (known after apply)
        + period_unit = (known after apply)
      }

    + node_info {
        + node_id   = (known after apply)
        + node_spec = "rds.mysql.1c2g"
        + node_type = "Primary"
        + zone_id   = "cn-beijing-a"
      }
    + node_info {
        + node_id   = (known after apply)
        + node_spec = "rds.mysql.1c2g"
        + node_type = "Secondary"
        + zone_id   = "cn-beijing-a"
      }
  }

Plan: 1 to add, 0 to change, 1 to destroy.

执行以下命令，应用执行计划。

terraform apply

执行后，在终端中会显示确认信息。如确认执行，则输入 yes；输入其他内容可取消执行计划。

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value:

输入 yes 后，开始执行计划。执行后，终端中会有以下提示消息。

$ terraform apply

...

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes
