Provides an Application Load Balancer resource.

-> NOTE: Available in 1.123.1+

-> NOTE: At present, to avoid some unnecessary regulation confusion, SLB can not support alicloud international account to create PayByBandwidth instance.

-> NOTE: The supported specifications vary by region. Currently, not all regions support guaranteed-performance instances. For more details about guaranteed-performance instance, see Guaranteed-performance instances.

Example Usage

# Create a intranet SLB instance
variable "slb_load_balancer_name" {
  default = "forSlbLoadBalancer"
}

data "alicloud_zones" "load_balancer" {
  available_resource_creation = "VSwitch"
}

resource "alicloud_vpc" "load_balancer" {
  vpc_name = var.slb_load_balancer_name
}

resource "alicloud_vswitch" "load_balancer" {
  vpc_id       = alicloud_vpc.load_balancer.id
  cidr_block   = "172.16.0.0/21"
  zone_id      = data.alicloud_zones.load_balancer.zones[0].id
  vswitch_name = var.slb_load_balancer_name
}

resource "alicloud_slb_load_balancer" "load_balancer" {
  load_balancer_name = var.slb_load_balancer_name
  address_type       = "intranet"
  load_balancer_spec = "slb.s2.small"
  vswitch_id         = alicloud_vswitch.load_balancer.id
  tags = {
    info = "create for internet"
  }
  instance_charge_type = "PayBySpec"
}

Deleting alicloud_slb_load_balancer or removing it from your configuration

The alicloud_slb_load_balancer resource allows you to manage payment_type = "Subscription" load balancer, but Terraform cannot destroy it. Deleting the subscription resource or removing it from your configuration will remove it from your state file and management, but will not destroy the Load Balancer. You can resume managing the subscription load balancer via the AlibabaCloud Console.

Argument Reference

The following arguments are supported:

• load_balancer_name - (Optional) The name of the SLB. This name must be unique within your AliCloud account, can have a maximum of 80 characters, must contain only alphanumeric characters or hyphens, such as "-","/",".","_", and must not begin or end with a hyphen. If not specified, Terraform will autogenerate a name beginning with tf-lb.
• address_type - (Optional, ForceNew) The network type of the SLB instance. Valid values: ["internet", "intranet"]. If load balancer launched in VPC, this value must be intranet.
  • internet: After an Internet SLB instance is created, the system allocates a public IP address so that the instance can forward requests from the Internet.
  • intranet: After an intranet SLB instance is created, the system allocates an intranet IP address so that the instance can only forward intranet requests.
• internet_charge_type - (Optional) Valid values are PayByBandwidth, PayByTraffic. If this value is PayByBandwidth, then argument address_type must be internet. Default is PayByTraffic. If load balancer launched in VPC, this value must be PayByTraffic. Before version 1.10.1, the valid values are paybybandwidth and paybytraffic.
• bandwidth - (Optional) Valid value is between 1 and 5120, If argument internet_charge_type is PayByTraffic, then this value will be ignored.
• vswitch_id - (Optional, ForceNew) The VSwitch ID to launch in. Note: Required for a VPC SLB. If address_type is internet, it will be ignored.
• load_balancer_spec - (Optional) The specification of the Server Load Balancer instance. Default to empty string indicating it is "Shared-Performance" instance. Launching "Performance-guaranteed" instance, it must be specified. Valid values: slb.s1.small, slb.s2.small, slb.s2.medium, slb.s3.small, slb.s3.medium, slb.s3.large and slb.s4.large. It will be ignored when instance_charge_type = "PayByCLCU".
• tags - (Optional, Computed) A mapping of tags to assign to the resource. The tags can have a maximum of 10 tag for every load balancer instance. This filed mark as Computed since v1.217.1.
• payment_type - (Optional) The billing method of the load balancer. Valid values are PayAsYouGo and Subscription. Default to PayAsYouGo.
• period - (Optional) The duration that you will buy the resource, in month. It is valid when PaymentType is Subscription. Default to 1. Valid values: [1-9, 12, 24, 36]. This attribute is only used to create Subscription instance or modify the PayAsYouGo instance to Subscription. Once effect, it will not be modified that means running terraform apply will not affect the resource.
• master_zone_id - (Optional, ForceNew) The primary zone ID of the SLB instance. If not specified, the system will be randomly assigned. You can query the primary and standby zones in a region by calling the DescribeZone API.
• slave_zone_id - (Optional, ForceNew) The standby zone ID of the SLB instance. If not specified, the system will be randomly assigned. You can query the primary and standby zones in a region by calling the DescribeZone API.
• delete_protection - (Optional) Whether enable the deletion protection or not. on: Enable deletion protection. off: Disable deletion protection. Default to off. Only postpaid instance support this function.
• address_ip_version - (Optional) The IP version of the SLB instance to be created, which can be set to ipv4 or ipv6 . Default to ipv4. Now, only internet instance support ipv6 address.
• address - (Optional) Specify the IP address of the private network for the SLB instance, which must be in the destination CIDR block of the corresponding switch.
• resource_group_id - (Optional, ForceNew) The id of resource group which the SLB belongs.
• modification_protection_reason - (Optional) The reason of modification protection. It's effective when modification_protection_status is ConsoleProtection.
• modification_protection_status - (Optional) The status of modification protection. Valid values: ConsoleProtection and NonProtection. Default value is NonProtection.
• status - (Optional) The status of slb load balancer. Valid values: active and inactice. The system default value is active.
• name - (Optional, Deprecated from v1.123.1) Field name has been deprecated from provider version 1.123.1 New field load_balancer_name instead.
• instance_charge_type - (Optional, V1.193.0+) Support PayBySpec (default) and PayByCLCU, This parameter takes effect when the value of payment_type (instance payment mode) is PayAsYouGo (pay-as-you-go).
• specification - (Optional, Deprecated from v1.123.1) Field specification has been deprecated from provider version 1.123.1 New field load_balancer_spec instead.
• internet - (Optional, Deprecated from v1.124.0) Field internet has been deprecated from provider version 1.124.0 New field address_type instead.

-> NOTE: A "Shared-Performance" instance can be changed to "Performance-guaranteed", but the change is irreversible.

-> NOTE: To change a "Shared-Performance" instance to a "Performance-guaranteed" instance, the SLB will have a short probability of business interruption (10 seconds-30 seconds). Advise to change it during the business downturn, or migrate business to other SLB Instances by using GSLB before changing.

-> NOTE: Currently, the alibaba cloud international account does not support creating a Subscription SLB instance.

-> NOTE: This parameter instance_charge_type is only valid for China sites and only if the payment_type value is PayAsYouGo.
