» aws_vpc_dhcp_options

Provides a VPC DHCP Options resource.

» Example Usage

Basic usage:

resource "aws_vpc_dhcp_options" "dns_resolver" {
  domain_name_servers = ["8.8.8.8", "8.8.4.4"]
}

Full usage:

resource "aws_vpc_dhcp_options" "foo" {
  domain_name          = "service.consul"
  domain_name_servers  = ["127.0.0.1", "10.0.0.2"]
  ntp_servers          = ["127.0.0.1"]
  netbios_name_servers = ["127.0.0.1"]
  netbios_node_type    = 2

  tags {
    Name = "foo-name"
  }
}

» Argument Reference

The following arguments are supported:

  • domain_name - (Optional) the suffix domain name to use by default when resolving non Fully Qualified Domain Names. In other words, this is what ends up being the search value in the /etc/resolv.conf file.
  • domain_name_servers - (Optional) List of name servers to configure in /etc/resolv.conf. If you want to use the default AWS nameservers you should set this to AmazonProvidedDNS.
  • ntp_servers - (Optional) List of NTP servers to configure.
  • 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.

» Remarks

  • Notice that all arguments are optional but you have to specify at least one argument.
  • domain_name_servers, netbios_name_servers, ntp_servers are limited by AWS to maximum four servers only.
  • To actually use the DHCP Options Set you need to associate it to a VPC using aws_vpc_dhcp_options_association.
  • If you delete a DHCP Options Set, all VPCs using it will be associated to AWS's default DHCP Option Set.
  • In most cases unless you're configuring your own DNS you'll want to set domain_name_servers to AmazonProvidedDNS.

» Attributes Reference

The following attributes are exported:

  • id - The ID of the DHCP Options Set.

You can find more technical documentation about DHCP Options Set in the official AWS User Guide.
