-- Creates a VPC endpoint for a specified AWS service. An endpoint enables you to create a private connection between your VPC and another AWS service in your account. You can specify an endpoint policy to attach to the endpoint that will control access to the service from your VPC. You can also specify the VPC route tables that use the endpoint.
--
--
-- Currently, only endpoints to Amazon S3 are supported.

-- | Creates a value of 'CreateVPCEndpoint' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'cvePolicyDocument' - A policy to attach to the endpoint that controls access to the service. The policy must be in valid JSON format. If this parameter is not specified, we attach a default policy that allows full access to the service.
--
-- * 'cveClientToken' - Unique, case-sensitive identifier you provide to ensure the idempotency of the request. For more information, see <http://docs.aws.amazon.com/AWSEC2/latest/APIReference/Run_Instance_Idempotency.html How to Ensure Idempotency> .
--
-- * 'cveDryRun' - 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@ .
--
-- * 'cveRouteTableIds' - One or more route table IDs.
--
-- * 'cveVPCId' - The ID of the VPC in which the endpoint will be used.
--
-- * 'cveServiceName' - The AWS service name, in the form @com.amazonaws./region/ ./service/ @ . To get a list of available services, use the 'DescribeVpcEndpointServices' request.
