Import VPC from existing stack

Hello,

typescript. I have an existing stack (non CDK, provisioned via aws cli). The stack has VCP resource and it is exported so that other stacks could use it.

aws cloudformation describe-stacks --stack-name network --query 'Stacks[*].Outputs[?ExportName==`VPC`]'

[
    [
        {
            "OutputKey": "VpcOutput",
            "OutputValue": "vpc-0d9c4bf811814d8f7",
            "Description": "The ID of VPC",
            "ExportName": "VPC"
        }
    ]
]

How can I import it and pass it to CDK so that it can be used as an input parameter to any construct that requires VPC?

thanks

@hoegertn Thanks for the reply. I don’t quite understand why would I ever need availibity zones or subnets. Isn’t unique VPC id enough to target an existing VPC?

This is at least how https://docs.aws.amazon.com/cli/latest/reference/ec2/create-security-group.html (and all SDks I have worked with) and cloudformation work, where VPC id is all they need.

@hoegertn - I am afraid I completely don’t undestand your statement. Say, I have 1 VPC and 3 subnets within the VPC. What if I pass only 2 subnets to ‘fromVpcAttributes’? Did I create a semi-constructed object? How does VPC imported with az1 and az2 differ from VPC with az3 and az4?

@NGL321 - I managed to reuse existing VPC, but I had to pass some meaningless attributes there were never used by the resource that needed the VPC. Go ahead and close it.
