Examples of common Terraform templates - Resource Orchestration Service

This topic provides examples of commonly used Terraform templates, including the templates that are used to separately create an Elastic Compute Service (ECS) instance, an ApsaraDB RDS instance, and a Server Load Balancer (SLB) instance.

Create an ECS instance

The following sample code provides an example of a template that is used to create a virtual private cloud (VPC), a vSwitch, a security group, and an ECS instance.

Note

You can run the sample code with a few clicks on the Code tab.

variable "region"{
  default = "cn-beijing"
}

provider "alicloud"{
  region = var.region
}

variable "instance_type" {
  type    = string
  default = "ecs.e-c1m1.large"
}

data "alicloud_zones" "default" {
  available_instance_type     = var.instance_type
  available_resource_creation = "VSwitch"
  available_disk_category     = "cloud_essd"
}

variable "vpc_cidr_block" {
  default = "172.16.0.0/16"
}

variable "vsw_cidr_block" {
  default = "172.16.0.0/24"
}

resource "random_integer" "default" {
  min = 10000
  max = 99999
}

resource "alicloud_vpc" "vpc" {
  vpc_name   = "vpc-test_${random_integer.default.result}"
  cidr_block = var.vpc_cidr_block
}

resource "alicloud_security_group" "group" {
  name   = "test_${random_integer.default.result}"
  vpc_id = alicloud_vpc.vpc.id
}

resource "alicloud_vswitch" "vswitch" {
  vpc_id       = alicloud_vpc.vpc.id
  cidr_block   = var.vsw_cidr_block
  zone_id      = data.alicloud_zones.default.zones[0].id
  vswitch_name = "vswitch-test-${random_integer.default.result}"
}

resource "alicloud_instance" "instance" {
  availability_zone          = data.alicloud_zones.default.zones[0].id
  security_groups            = alicloud_security_group.group.*.id

  system_disk_category       = "cloud_essd"
  system_disk_name           = "test_foo_system_disk_${random_integer.default.result}"
  system_disk_description    = "test_foo_system_disk_description"
  image_id                   = "aliyun_2_1903_x64_20G_alibase_20240628.vhd"

  internet_max_bandwidth_out = 10
  password                   = "Terraform@Example"
}

Create an ApsaraDB RDS Instance

The following sample code provides an example of a template that is used to create a VPC, a vSwitch, and an ApsaraDB RDS instance.

Note

You can run the sample code with a few clicks on the Code tab.

variable "region" {
  default = "cn-beijing"
}

provider "alicloud" {
  region = var.region
}

data "alicloud_zones" "default" {
  available_resource_creation = "VSwitch"
  available_disk_category     = "cloud_essd"
}

variable "vpc_cidr_block" {
  default = "172.16.0.0/16"
}

variable "vsw_cidr_block" {
  default = "172.16.0.0/24"
}

resource "random_integer" "default" {
  min = 10000
  max = 99999
}

resource "alicloud_vpc" "vpc" {
  vpc_name   = "vpc-test_${random_integer.default.result}"
  cidr_block = var.vpc_cidr_block
}

resource "alicloud_vswitch" "vswitch" {
  vpc_id       = alicloud_vpc.vpc.id
  cidr_block   = var.vsw_cidr_block
  zone_id      = data.alicloud_zones.default.zones[0].id
  vswitch_name = "vswitch-test-${random_integer.default.result}"
}

resource "alicloud_db_instance" "example" {
  engine               = "MySQL"
  engine_version       = "5.6"
  instance_type        = "rds.mysql.s2.large"
  instance_storage     = "30"
  instance_charge_type = "Postpaid"
  instance_name        = "my_db_${random_integer.default.result}"
  vswitch_id           = alicloud_vswitch.vswitch.id
  monitoring_period    = "60"
}

Create an SLB instance

The following sample code provides an example of a template that is used to create a VPC, a vSwitch, and an SLB instance.

Note

You can run the sample code with a few clicks on the Code tab.

variable "region" {
  default = "cn-beijing"

  cidr_block   = var.vsw_cidr_block
  zone_id      = data.alicloud_zones.default.zones[0].id
  vswitch_name = "vswitch-test-${random_integer.default.result}"
}

resource "alicloud_slb_load_balancer" "default" {
  load_balancer_name = "my_slb_${random_integer.default.result}"
  load_balancer_spec = "slb.s2.small"
  vswitch_id         = alicloud_vswitch.vswitch.id
}
