public class CfnVPC
extends CfnResource
implements IInspectable

A CloudFormation `AWS::EC2::VPC`.

Specifies a VPC with the specified IPv4 CIDR block. The smallest VPC you can create uses a /28 netmask (16 IPv4 addresses), and the largest uses a /16 netmask (65,536 IPv4 addresses). For more information about how large to make your VPC, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide .

Example:

 CfnInclude cfnTemplate;
 // using from*Attributes()
 CfnSubnet privateCfnSubnet1;
 CfnSubnet privateCfnSubnet2;
 // using from*Name()
 CfnBucket cfnBucket = (CfnBucket)cfnTemplate.getResource("Bucket");
 IBucket bucket = Bucket.fromBucketName(this, "L2Bucket", cfnBucket.getRef());
 // using from*Arn()
 CfnKey cfnKey = (CfnKey)cfnTemplate.getResource("Key");
 IKey key = Key.fromKeyArn(this, "L2Key", cfnKey.getAttrArn());
 CfnVPC cfnVpc = (CfnVPC)cfnTemplate.getResource("Vpc");
 IVpc vpc = Vpc.fromVpcAttributes(this, "L2Vpc", VpcAttributes.builder()
         .vpcId(cfnVpc.getRef())
         .availabilityZones(Fn.getAzs())
         .privateSubnetIds(List.of(privateCfnSubnet1.getRef(), privateCfnSubnet2.getRef()))
         .build());
