aws_ec2: New construct - CfnSubnetCidrReservation

[williwlwilliwll]

Describe the feature

(Unless I'm going crazy) I don't think there is a way to create subnet CIDR reservations through the CDK like there is through the SDK, API, or CLI (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateSubnetCidrReservation.html). I propose a new L1 construct - CfnSubnetCidrReservation - to fill this gap.

Use Case

After deploying my beautiful CDK stacks I then have to manually create the CIDR reservations myself. I would love to have the process fully automated.

Proposed Solution

Create a new L1 construct - CfnSubnetCidrReservation

Other Information

No response

Hi @williwlwilliwll , thanks for reaching out. I checked cloudformation resource specification docs and found that there is no such L1 construct for SubnetCidrReservation, the only available construct for Cidr is-

AWS:EC2:SubnetCidrBlock - CfnSubnetCidrBlock

Since this needs support from Cloudformation first, I would recommend you to create a FR with Cloudformation team, on their Coverage roadmap.

Let me know if you need any further help! Thanks

Thanks @khushail, have created one now - aws-cloudformation/cloudformation-coverage-roadmap#2127
