Argument Reference

The following arguments are supported:

address_ip_version - (Optional, ForceNew) The protocol version. Valid values:
- ipv4: IPv4. This is the default value.
- DualStack: dual stack.
address_type - (Required) The type of IPv4 address used by the NLB instance. Valid values:
- Internet: The NLB instance uses a public IP address. The domain name of the NLB instance is resolved to the public IP address. Therefore, the NLB instance can be accessed over the Internet.
- Intranet: The NLB instance uses a private IP address. The domain name of the NLB instance is resolved to the private IP address. Therefore, the NLB instance can be accessed over the virtual private cloud (VPC) where the NLB instance is deployed.

-> NOTE: To enable a public IPv6 address for an NLB instance, call the EnableLoadBalancerIpv6Internet operation.

bandwidth_package_id - (Optional, ForceNew) The ID of the EIP bandwidth plan that is associated with the Internet-facing NLB instance.
cross_zone_enabled - (Optional) Specifies whether to enable cross-zone load balancing for the NLB instance. Valid values:
- true
- false
deletion_protection_config - (Optional, List) Specifies whether to enable deletion protection. Default value: false. See deletion_protection_config below.
ipv6_address_type - (Optional) The type of IPv6 address used by the NLB instance. Valid values:
- Internet: a public IP address. The domain name of the NLB instance is resolved to the public IP address. Therefore, the NLB instance can be accessed over the Internet.
- Intranet: a private IP address. The domain name of the NLB instance is resolved to the private IP address. Therefore, the NLB instance can be accessed over the VPC where the NLB instance is deployed.
load_balancer_name - (Optional) The name of the NLB instance.

The value must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). The value must start with a letter.
load_balancer_type - (Optional, ForceNew, Computed) The type of the Server Load Balancer (SLB) instance. Set the value to network, which specifies NLB.
modification_protection_config - (Optional, List) Specifies whether to enable the configuration read-only mode. Default value: NonProtection. See modification_protection_config below.
resource_group_id - (Optional, Computed) The ID of the new resource group.

You can log on to the Resource Management console to view resource group IDs.
security_group_ids - (Optional, Set) The security group to which the network-based SLB instance belongs.
tags - (Optional, Map) List of labels.
vpc_id - (Required, ForceNew) The ID of the VPC where the NLB instance is deployed.
zone_mappings - (Required, Set) Available Area Configuration List. You must add at least two zones. You can add a maximum of 10 zones. See zone_mappings below.

`deletion_protection_config`

The deletion_protection_config supports the following:

enabled - (Optional) Specifies whether to enable deletion protection. Valid values:
- true: yes
- false (default): no
reason - (Optional) The reason why deletion protection is enabled. The reason must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). The reason must start with a letter.

-> NOTE: This parameter takes effect only when DeletionProtectionEnabled is set to true.

`modification_protection_config`

The modification_protection_config supports the following:

reason - (Optional) The reason why the configuration read-only mode is enabled. The value must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). The value must start with a letter.

-> NOTE: This parameter takes effect only if the status parameter is set to ConsoleProtection.

status - (Optional) Specifies whether to enable the configuration read-only mode. Valid values:
- NonProtection: disables the configuration read-only mode. In this case, you cannot set the ModificationProtectionReason parameter. If you specify ModificationProtectionReason, the value is cleared.
- ConsoleProtection: enables the configuration read-only mode. In this case, you can specify ModificationProtectionReason.

-> NOTE: If you set this parameter to ConsoleProtection, you cannot use the NLB console to modify instance configurations. However, you can call API operations to modify instance configurations.

`zone_mappings`

The zone_mappings supports the following:

allocation_id - (Optional) The ID of the elastic IP address (EIP) that is associated with the Internet-facing NLB instance. You can specify one EIP for each zone. You must add at least two zones. You can add a maximum of 10 zones.
private_ipv4_address - (Optional, Computed) The private IP address. You must add at least two zones. You can add a maximum of 10 zones.
status - (Optional, Computed) Zone Status
vswitch_id - (Required) The vSwitch in the zone. You can specify only one vSwitch (subnet) in each zone of an NLB instance. You must add at least two zones. You can add a maximum of 10 zones.
zone_id - (Required) The ID of the zone of the NLB instance. You must add at least two zones. You can add a maximum of 10 zones.

You can call the DescribeZones operation to query the most recent zone list.
