AWS EC2 Create Subnet VERSION 1


Creates a subnet in an existing VPC. For more information see the AWS Amazon Virtual Private Cloud User Guide online.

The Dry Run parameter validates user permissions and inputs. If it is set to true, an error will always be thrown by the handler before completing the handler action. Error response will be 'DryRunOperation' if the account has proper permissions and inputs; 'UnauthorizedOperation' if the account does not have proper permissions.


Parameters

NameDescription
Dry RunDry run validates user permissions and inputs without completing the EC2 action (true or false).
VPC IdThe ID of the VPN in which the subnet will be created. Must match an existing value in AWS.
CIDR BlockThe network range for the subnet, in CIDR notation. For example: 10.0.0.0/24. After a subnet is created, the CIDR block cannot be changed. The subnet's CIDR Block can be the same as the VPC's CIDR block, or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).
Availability ZoneThe availability zone for the subnet.
