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。本文介绍通过 Terraform 创建云数据库 MySQL 版实例的操作流程。
已参考安装 Terraform，完成 Terraform 的安装。
创建一个文件夹，并在该文件夹中创建名为main.tf的配置文件。
data "volcengine_zones" "foo" { } resource "volcengine_vpc" "foo" { vpc_name = "vpc-test" cidr_block = "172.16.0.0/16" } resource "volcengine_subnet" "foo" { subnet_name = "subnet-test" cidr_block = "172.16.0.0/24" zone_id = data.volcengine_zones.foo.zones[0].id vpc_id = volcengine_vpc.foo.id } resource "volcengine_rds_mysql_instance" "foo" { db_engine_version = "MySQL_5_7" node_spec = "rds.mysql.1c2g" primary_zone_id = data.volcengine_zones.foo.zones[0].id secondary_zone_id = data.volcengine_zones.foo.zones[0].id storage_space = 80 subnet_id = volcengine_subnet.foo.id instance_name = "mysql-test" lower_case_table_names = "1" charge_info { charge_type = "PostPaid" } parameters { parameter_name = "auto_increment_increment" parameter_value = "2" } parameters { parameter_name = "auto_increment_offset" parameter_value = "5" } project_name = "default" tags { key = "k1" value = "v1" } }
初始化 Terraform 运行环境。
terraform init
预期执行结果如下所示。
Initializing the backend... Initializing provider plugins... - Finding latest version of hashicorp/volcengine... - Installing hashicorp/volcengine v0.0.1... - Installed hashicorp/volcengine v0.0.1 (unauthenticated) Terraform has created a lock file .terraform.lock.hcl to record the provider selections it made above. Include this file in your version control repository so that Terraform can guarantee to make the same selections by default when you run "terraform init" in the future. .... Terraform has been successfully initialized! You may now begin working with Terraform. Try running "terraform plan" to see any changes that are required for your infrastructure. All Terraform commands should now work. If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.
进行资源规划。
