像 git 一样,每个 Terraform 项目需要自己单独的目录空间,所以我们创建一个 terraform-learning 目录
 +
 +
    mkdir terraform-learning
 +
    cd terraform-learning
 +
 +
该目录下的所有  *.tf 文件都会被 Terraform 加载,在初始化 Terraform 工作空间之前必须至少要有一个 *.tf 文件。我们这里建立文件 main.tf, 内容如下

Terraform has created a lock file .terraform.lock.hcl to record the provider

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.


terraform apply #

Terraform used the selected providers to generate the following execution plan.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # alicloud_vswitch.vsw will be created
  + resource "alicloud_vswitch" "vsw" {
      + availability_zone = (known after apply)
      + cidr_block        = "172.16.0.0/21"

打开 web 有了

terraform show ##查看已创建的专有网络和交换机

# alicloud_vpc.vpc:
resource "alicloud_vpc" "vpc" {
    cidr_block            = "172.16.0.0/12"
    id                    = "vpc-7xvsw3jjadaf53zjlido6"
    name                  = "tf_test_foo"
    route_table_id        = "vtb-7xvjpppz3q8kin5vi081k"
    router_id             = "vrt-7xvi5nvfqmvg0mox9rj5j"
    router_table_id       = "vtb-7xvjpppz3q8kin5vi081k"
    secondary_cidr_blocks = []
    status                = "Available"
    user_cidrs            = []
    vpc_name              = "tf_test_foo"
}

# alicloud_vswitch.vsw:
resource "alicloud_vswitch" "vsw" {
    availability_zone = "cn-guangzhou-b"
    cidr_block        = "172.16.0.0/21"
    id                = "vsw-7xvwa2oq0fsjm3xuhv9ss"
    status            = "Available"
    vpc_id            = "vpc-7xvsw3jjadaf53zjlido6"
    zone_id           = "cn-guangzhou-b"
}

2 在上一步创建的专有网络中创建一个安全组,并添加一个允许任何地址访问的安全组规则。
在terraform.tf文件中增加以下内容。
resource "alicloud_security_group" "default" {
  name = "default"
  vpc_id = alicloud_vpc.vpc.id
}

resource "alicloud_security_group_rule" "allow_all_tcp" {
  type              = "ingress"
  ip_protocol       = "tcp"
  nic_type          = "intranet"
  policy            = "accept"
  port_range        = "1/65535"
  priority          = 1
  security_group_id = alicloud_security_group.default.id
  cidr_ip           = "0.0.0.0/0"
}
运行terraform apply #开始创建。 有时time out 再来一次就好了 
运行terraform show查看已创建的安全组和安全组规则。
您也可以登录ECS控制台查看安全组和安全组规则。
https://ecs.console.aliyun.com/?spm=5176.10483814.recommend.decs.78e6124322cN4j#/securityGroup/region/cn-guangzhou

3.创建ECS实例。
在terraform.tf文件中增加以下内容。
resource "alicloud_instance" "instance" {
  # cn-beijing
  availability_zone = "cn-beijing-b"
  security_groups = alicloud_security_group.default.*.id

  # series III 能找个最小的么   ecs.s6-c1m1.small
  instance_type        = "ecs.s6-c1m1.small"
  #instance_type        = "ecs.n2.small"
  system_disk_category = "cloud_efficiency"
  image_id             = "ubuntu_18_04_64_20G_alibase_20190624.vhd"
  instance_name        = "test_foo"
  vswitch_id = alicloud_vswitch.vsw.id
  internet_max_bandwidth_out =10
  password = "$Eevan2240881"
}

说明
在上述示例中,指定了internet_max_bandwidth_out= 10,因此会自动为实例分配一个公网IP。
详细的参数解释请参见

 image_id 指定ubuntu_16_0402_32,最终会匹配ubuntu_16_0402_32_40G_alibase_20170711.vhd。

最终比较完整的配置文件

  
evan@myxps:~/.terraform.d$ cat terraform.tf
resource "alicloud_vpc" "vpc" {
  vpc_name       = "tf_test_foo"
  cidr_block = "172.16.0.0/12"
}

resource "alicloud_vswitch" "vsw" {
  vpc_id            = alicloud_vpc.vpc.id
  cidr_block        = "172.16.0.0/21"
  zone_id = "cn-guangzhou-b"
}

resource "alicloud_security_group" "default" {
  name = "default"
  vpc_id = alicloud_vpc.vpc.id
}

resource "alicloud_security_group_rule" "allow_all_tcp" {
  type              = "ingress"
  ip_protocol       = "tcp"
  nic_type          = "intranet"
  policy            = "accept"
  port_range        = "1/65535"
  priority          = 1
  security_group_id = alicloud_security_group.default.id
  cidr_ip           = "0.0.0.0/0"
}

#ec2 create 
resource "alicloud_instance" "instance" {
  # cn-beijing
  availability_zone = "cn-guangzhou-b"
  security_groups = alicloud_security_group.default.*.id

  # series III 能找个最小的么   ecs.s6-c1m1.small
  instance_type        = "ecs.s6-c1m1.small"
  #instance_type        = "ecs.n2.small"
  system_disk_category = "cloud_efficiency"
  image_id             = "centos_7_9_x64_20G_alibase_20201228.vhd"
  instance_name        = "test_foo"
  vswitch_id = alicloud_vswitch.vsw.id
  internet_max_bandwidth_out =10
  password = "$1234567890"
}

  NOTES 将秘钥直接填入到.tf文件中是十分不安全的,在多用户共同管理资源时,不建议把腾讯云API 的秘钥直接写到源代码里,以免一不小心更新到公开的版本中,造成安全风险。

腾讯云提供了另一种更为安全可靠的方式,把秘钥信息放在环境变量中配置

    // Configure the secret key in the environment path
    $ export TENCENTCLOUD_SECRET_ID="your_fancy_accessid"
    $ export TENCENTCLOUD_SECRET_KEY="your_fancy_accesskey"
    $ export TENCENTCLOUD_REGION="ap-hongkong"

这样在 provider.tf 文件中就可以省略掉相关信息

    $ vim provider.tf
    
    // provider.tf
    provider "tencentcloud" {}
