Description: Creates Custom VPC
Metadata:
  Name: chp-vpc-custom
  Version: 0.2.3
  AWS::CloudFormation::Interface:
    ParameterGroups:
      - Label:
          default: VPC Name
        Parameters:
          - VpcName
      - Label:
          default: >-
            Subnet Configuration:
            VPC size CAN NOT EXCEED /16 or 65,534 IP addresses.
            For example: The stack would not get created if you pick 6XL (/18) for both private
            and alternate subnets. 6XL means 16k IP addresses and it would try to create 3 private
            subnets and 3 alternate subnets each with 16k IP addresses, which adds up to 98k IP addresses.
        Parameters:
          - PrivateSubnetSize
          - DataSubnetSize
          - IngressSubnetSize
          - EgressSubnetSize
