aws ec2 create-transit-gateway

Creates a transit gateway. You can use a transit gateway to interconnect your virtual private clouds (VPC) and on-premises networks. After the transit gateway enters the available state, you can attach your VPCs and VPN connections to the transit gateway. To attach your VPCs, use CreateTransitGatewayVpcAttachment. To attach a VPN connection, use CreateCustomerGateway to create a customer gateway and specify the ID of the customer gateway and the ID of the transit gateway in a call to CreateVpnConnection. When you create a transit gateway, we create a default transit gateway route table and use it as the default association route table and the default propagation route table. You can use CreateTransitGatewayRouteTable to create additional transit gateway route tables. If you disable automatic route propagation, we do not create a default transit gateway route table. You can use EnableTransitGatewayRouteTablePropagation to propagate routes from a resource attachment to a transit gateway route table. If you disable automatic associations, you can use AssociateTransitGatewayRouteTable to associate a resource attachment with a transit gateway route table

Options

NameDescription
--description <string>A description of the transit gateway
--options <structure>The transit gateway options
--tag-specifications <list>The tags to apply to the transit gateway
--dry-runChecks 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
--no-dry-runChecks 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
