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.

--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.

Examples

Command:

aws ec2 describe-vpc-attribute --vpc-id vpc-a01106c2 --attribute enableDnsSupport

Output:

{
    "VpcId": "vpc-a01106c2",
    "EnableDnsSupport": {
        "Value": true
    }
}

To describe the enableDnsHostnames attribute

This example describes the enableDnsHostnames attribute. This attribute indicates whether the instances launched in the VPC get DNS hostnames. If this attribute is true, instances in the VPC get DNS hostnames; otherwise, they do not.

Command:

Output:

{
    "VpcId": "vpc-a01106c2",
