6、创建实例

7、如果想清理创建的实例，则执行

1、使用下列命令安装terraform

bash 复制代码

yum install -y yum-utils
yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
yum -y install terraform

2、安装后，查看版本

bash 复制代码

terraform --version

3、编辑tf文件

TypeScript 复制代码

详细的配置信息可以参考terraform官网：
https://registry.terraform.io/providers/aliyun/alicloud/latest/docs

示例如下：

bash 复制代码

# Configure the AliCloud Provider

provider "alicloud" {
  access_key = var.access_key
  secret_key = var.secret_key
  # If not set, cn-beijing will be used.
  region = var.region
}

variable "name" {
  default = "terraform-example"
}

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

# Create a new ECS instance for VPC
resource "alicloud_vpc" "vpc" {
  vpc_name   = var.name
  cidr_block = "172.16.0.0/16"
}

resource "alicloud_vswitch" "vswitch" {
  vpc_id       = alicloud_vpc.vpc.id
  cidr_block   = "172.16.0.0/24"
  zone_id      = data.alicloud_zones.default.zones.0.id
  vswitch_name = var.name
}

# Create a new Security in a VPC
resource "alicloud_security_group" "group" {
  name        = var.name
  description = "foo"
  vpc_id      = alicloud_vpc.vpc.id
}
# Create a kms to encrypt the disk
resource "alicloud_kms_key" "key" {
  description            = "Hello KMS"
  pending_window_in_days = "7"
  status                 = "Enabled"
}

resource "alicloud_instance" "instance" {
  # cn-beijing
  availability_zone = data.alicloud_zones.default.zones.0.id
  security_groups   = alicloud_security_group.group.*.id

  # series III
  instance_type              = "ecs.n4.large"
  system_disk_category       = "cloud_efficiency"
  system_disk_name           = var.name
  system_disk_description    = "system_disk_description"
  image_id                   = "ubuntu_18_04_64_20G_alibase_20190624.vhd"
  instance_name              = var.name
  vswitch_id                 = alicloud_vswitch.vswitch.id
  internet_max_bandwidth_out = 10
  data_disks {
    name        = "data-disk"
    size        = 20
    category    = "cloud_efficiency"
    description = "disk-description"
    encrypted   = true
    kms_key_id  = alicloud_kms_key.key.id
  }
}

4、初始化

复制代码

terraform init

***注：上面的提示可以不用管。如果想彻底解决就更新 required_providers 中的 source 为 aliyun/alicloud 即可.

5、terraform 预览，在执行实际变更前，先展示下要做什么

复制代码

terraform plan

6、创建实例

复制代码

terraform apply

成功，如下图所示

7、如果想清理创建的实例，则执行

bash 复制代码

terraform destroy
