AWS CDK (TypeScript) - VPC, subnets and routing tables

Question

Hello,

I am new to using AWS CDK, I need to set up the network infrastructure in code using AWS CDK(Typescript). I have tried setting some basic infrastructure and at it seems to work, however, I don't seem to have any control over being able to rename any of the stacks I have created to something simple like test-vpc instead of being given [STACK/STACKNAME/TEST-VPC/subnet. Also when creating the routing table for the VPC it created multiple extra tables that I did not define, almost like its creating default tables in addition to my code.

It seems to me anyway that its a lot easier to create this via cloud formation (more control of resource names and referencing)

My question - is there any tips or guides to help define the CDK code for networking, I have only got as far as the basics and still got a long way to go with the likes of creating TGWs, NFWs

Any good example of a VPC, subnet and route table association CDK stacks that I could use?

Thanks

Hi,

On your question about choosing physical stack names with CDK, look at https://docs.aws.amazon.com/cdk/v2/guide/stacks.html 
at end of section preceding section 'Stack API', you have examples in all languages

```
The physical names of the AWS CloudFormation stacks are automatically determined 
by the AWS CDK based on the stack's construct path in the tree. By default, a stack's 
name is derived from the construct ID of the Stack object. However, you can specify 
an explicit name by using the stackName prop (in Python, stack_name), as follows.
```

On good sample, see for example https://github.com/sebsto/cdk-vpc-example/blob/master/bin/vpc-ingress-routing.ts

class VpcIngressRoutingStack is a good example

Hope it helps!
