-> NOTE: Deprecated since v1.123.1.

-> DEPRECATED: This resource has been renamed to alicloud_slb_load_balancer from version 1.123.1.

Provides an Application Load Balancer resource.

-> 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.

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.
• name - (Optional, Deprecated from v1.123.1) Field name has been deprecated from provider version 1.123.1 New field load_balancer_name instead.
• internet - (Removed since v1.124.0) Field internet has been removed from provider version 1.124.0. Use address_type replaces it.
• address_type - (Optional, ForceNew, Available since v1.55.3) 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, ForceNew) Valid values are PayByBandwidth, PayByTraffic. If this value is "PayByBandwidth", then argument "internet" must be "true". 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 1000, If argument "internet_charge_type" is "paybytraffic", then this value will be ignore.
• vswitch_id - (Optional, ForceNew) The vSwitch ID to launch in. If address_type is internet, it will be ignore.
• specification - (Optional, Deprecated from v1.123.1) The specification of the Server Load Balancer instance. Default to empty string indicating it is "Shared-Performance" instance. Launching "Performance-guaranteed" instance, it is must be specified and it valid values are: "slb.s1.small", "slb.s2.small", "slb.s2.medium", "slb.s3.small", "slb.s3.medium", "slb.s3.large" and "slb.s4.large".
• tags - (Optional) A mapping of tags to assign to the resource. The tags can have a maximum of 10 tag for every load balancer instance.
• instance_charge_type - (Optional, Available since v1.34.0) The billing method of the load balancer. Valid values are "PrePaid" and "PostPaid". Default to "PostPaid".
• period - (Optional, Available since v1.34.0) The duration that you will buy the resource, in month. It is valid when instance_charge_type is PrePaid. Valid values: [1-9, 12, 24, 36]. -> NOTE: The attribute period 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 effect the resource.
• master_zone_id - (Optional, ForceNew, Available since v1.36.0) 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, Available since v1.36.0) 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, Available since v1.51.0) 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, ForceNew, Available since v1.55.2) 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, ForceNew, Available since v1.55.2) Specify the IP address of the private network for the SLB instance, which must be in the destination CIDR block of the correspond ing switch.
• resource_group_id - (Optional, ForceNew, Available since v1.55.3) The Id of resource group which the SLB belongs.
• 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.
• 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: NonProtection.
• payment_type - (Optional) The billing method of the load balancer. Valid values are PayAsYouGo and Subscription. Default to PayAsYouGo.
• status - (Optional) The status of slb load balancer. Valid values: active and inactice. The system default value is active.

-> 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 PrePaid SLB instance.
