Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).
AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.
Creates a set of DHCP options for your VPC. After creating the set, you must associate it with the VPC, causing all existing and new instances that you launch in the VPC to use this set of DHCP options. The following are the individual DHCP options you can specify. For more information about the options, see RFC 2132 .
Your VPC automatically starts out with a set of DHCP options that includes only a DNS server that we provide (AmazonProvidedDNS). If you create a set of options, and if your VPC has an internet gateway, make sure to set the domain-name-servers option either to AmazonProvidedDNS or to a domain name server of your choice. For more information, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide .

--dry-run | --no-dry-run (boolean)
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .
--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

To create a set of DHCP options
The following create-dhcp-options example creates a set of DHCP options that specifies the domain name, the domain name servers, and the NetBIOS node type.
aws ec2 create-dhcp-options \
--dhcp-configuration \
"Key=domain-name-servers,Values=10.2.5.1,10.2.5.2" \
"Key=domain-name,Values=example.com" \
"Key=netbios-node-type,Values=2"
Output:
{
"DhcpOptions": {
"DhcpConfigurations": [
{
"Key": "domain-name",
"Values": [
{
"Value": "example.com"
}
]
},
{
"Key": "domain-name-servers",
"Values": [
{
"Value": "10.2.5.1"
},
{
"Value": "10.2.5.2"
}
]
},
{
"Key": "netbios-node-type",
"Values": [
{
"Value": "2"
}
]
}
],
