To deploy a new stack use the AWS CLI command:
aws cloudformation create-stack --stack-name temp-stack-dev --template-body vpc-template.yaml --parameters Parameters/dev-parameters.json
To update an existing VPC use the AWS CLI command:
aws cloudformation update-stack --stack-name temp-stack-dev --template-body vpc-template.yaml --parameters Parameters/dev-parameters.json
''' cli eksctl create cluster \n--name dev-cluster15 \n--region us-east-2 \n--with-oidc \n--ssh-access \n--ssh-public-key eks-us-east2 '''
''' cli aws cloudformation update-stack --stack-name dev-test-vpc --template-body file://vpc-template.yaml --parameters file://Parameters/dev-test-parameters.json --capabilities CAPABILITY_IAM '''

Transit GW Notes Attaching a VPC to a TGW enables routing only. The VPCs need to have rout table entries added that indicate where to route traffic to other VPCs ie vpc destination target A 10.0.0.0/16 local A 10.0.0.0/8 tgw-xxx
B 10.1.0.0/16 local B 10.0.0.0/8 tgw-xxx
There must also be a security groups that allows the traffic to flow
