» aws_default_vpc_dhcp_options

Provides a resource to manage the default AWS DHCP Options Set in the current region.

Each AWS region comes with a default set of DHCP options. This is an advanced resource, and has special caveats to be aware of when using it. Please read this document in its entirety before using this resource.

The aws_default_vpc_dhcp_options behaves differently from normal resources, in that Terraform does not create this resource, but instead "adopts" it into management.

» Example Usage

Basic usage with tags:

resource "aws_default_vpc_dhcp_options" "default" {
  tags = {
    Name = "Default DHCP Option Set"

» Argument Reference

The arguments of an aws_default_vpc_dhcp_options differ slightly from aws_vpc_dhcp_options resources. Namely, the domain_name, domain_name_servers and ntp_servers arguments are computed. The following arguments are still supported:

  • netbios_name_servers - (Optional) List of NETBIOS name servers.
  • netbios_node_type - (Optional) The NetBIOS node type (1, 2, 4, or 8). AWS recommends to specify 2 since broadcast and multicast are not supported in their network. For more information about these node types, see RFC 2132.
  • tags - (Optional) A mapping of tags to assign to the resource.

» Removing aws_default_vpc_dhcp_options from your configuration

The aws_default_vpc_dhcp_options resource allows you to manage a region's default DHCP Options Set, but Terraform cannot destroy it. Removing this resource from your configuration will remove it from your statefile and management, but will not destroy the DHCP Options Set. You can resume managing the DHCP Options Set via the AWS Console.

» Attributes Reference

In addition to all arguments above, the following attributes are exported:

  • id - The ID of the DHCP Options Set.
  • owner_id - The ID of the AWS account that owns the DHCP options set.
