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.
terraform apply #

alicloud_vpc.vpc: Refreshing state... [id=vpc-7xvsw3jjadaf53zjlido6]
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"
+ id = (known after apply)
+ name = (known after apply)
+ status = (known after apply)
+ vpc_id = "vpc-7xvsw3jjadaf53zjlido6"
+ vswitch_name = (known after apply)
+ zone_id = "cn-guangzhou-b"
}
Plan: 1 to add, 0 to change, 0 to destroy.
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

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
