AWS VPC IPAM Test

vpc_ipam_test

Provisioning a VPC using an IPAM Pool

Then import the VPC and try to provision

Running Terraform v1.3.7 and Terraform AWS Provider v5.24.0

Provision

terraform init
terraform apply

Save vpc_id from Outputs of apply. Use this in the next step:

VPC_ID="vpc-122523421532"

Test import

cd import
terraform init
terraform import aws_vpc.test $VPC_ID
terraform plan

Don't apply, refer to the plan, example here:
