Edge Security Acceleration:Use Terraform to add DNS records for an ESA site

Define the provider and Terraform version

First, create a configuration file named providers.tf and copy the following code to the file. This file is used to centrally manage all provider configurations and version constraints.

terraform {
  required_providers {
    alicloud = {
      source  = "aliyun/alicloud"
      version = "1.245.0"
    }
  }
}

Define resource variables

To improve code reusability, declare input variables and local variables. To do this, create a configuration file named variables.tf and copy the following code to the file.

# The connection type of the site. Valid values: CNAME and NS.
variable "site_type" {
  default = "NS"
}
# The billing method. The value must be Subscription. Other values are not supported.
variable "payment_type" {
  default = "Subscription"
}
# The area where the endpoint is deployed. Valid values:
# domestic (the Chinese mainland), overseas (global, excluding the Chinese mainland), and global (global).
variable "coverage_name" {
  default = "overseas"
}
# Specifies whether to enable auto-renewal.
variable "auto_pay" {
  default = "true"
}
# The valid values of the plan name are as follows:
# entranceplan_intl (Entrance Edition), basicplan_intl (Pro Edition), and vipplan_intl (Premium Edition).
variable "plan_name" {
  default = "entranceplan_intl"
}
# The site name. You must replace the value with your domain name.
variable "site_name" {
  default = "aliyundoc.com"
}
# The value of the origin server, which is your origin domain name.
variable "record_value" {
  default = "www.example.com"
}
# The port for origin fetch, which is the port number of your source port.
variable "record_port" {
  default = "80"
}
# The DNS record value, which is the accelerated domain name.
variable "record_name" {
  default = "_udp._sip.aliyundoc.com"
}
# The DNS record type.
variable "record_type" {
  default = "SRV"
}

Define resources

Finally, create a configuration file named main.tf and copy the following code to the file. This file serves as the main entry point for all resource declarations.

# Create a plan.
resource "alicloud_esa_rate_plan_instance" "my_plan" {
  type         = var.site_type
  auto_renew   = "false"
  period       = "1"
  payment_type = var.payment_type
  coverage     = var.coverage_name
  auto_pay     = var.auto_pay
  plan_name    = var.plan_name
}

# Create a site.
resource "alicloud_esa_site" "my_site" {
  site_name   = var.site_name
  instance_id = alicloud_esa_rate_plan_instance.my_plan.id
  coverage    = var.coverage_name
  access_type = var.site_type
}

# Add a DNS record.
resource "alicloud_esa_record" "my_record" {
  data {
    value    = var.record_value
    weight   = "1"
    priority = "1"
    port     = var.record_port
  }

  ttl         = "100"
  record_name = var.record_name
  comment     = "This is a remark"
  site_id     = alicloud_esa_site.my_site.id
  record_type = var.record_type
}

View the plan

1. Log on to the ESA console. In the navigation pane on the left, choose Billing Management > Plans.

2. On the Plan Management page, you can view the new plan, as shown in the following figure.

   

View the site

In the ESA console, choose Websites. You can view the new site, as shown in the following figure.

View DNS records

1. In the ESA console, choose Websites, and click the name of the target site in the Website column.
