@Generated(value="jsii-pacmak/1.98.0 (build 00b106d)", date="2024-05-08T21:35:06.271Z") @Stability(Stable) public class Vpc extends Resource implements IVpc
Define an AWS Virtual Private Cloud.

See the package-level documentation of this package for an overview of the various dimensions in which you can configure your VPC.

For example: 

 Vpc vpc = Vpc.Builder.create(this, "TheVPC")
         .ipAddresses(IpAddresses.cidr("10.0.0.0/16"))
         .build();
 // Iterate the private subnets
 SelectedSubnets selection = vpc.selectSubnets(SubnetSelection.builder()
         .subnetType(SubnetType.PRIVATE_WITH_EGRESS)
         .build());
 for (Object subnet : selection.getSubnets()) {
 }

Example: 

 import software.amazon.awscdk.services.ec2.*;
 Vpc vpc = Vpc.Builder.create(this, "Vpc")
         .ipAddresses(IpAddresses.cidr("10.0.0.0/16"))
         .build();
 VpcConnector vpcConnector = VpcConnector.Builder.create(this, "VpcConnector")
         .vpc(vpc)
         .vpcSubnets(vpc.selectSubnets(SubnetSelection.builder().subnetType(SubnetType.PUBLIC).build()))
         .vpcConnectorName("MyVpcConnector")
         .build();
 Service.Builder.create(this, "Service")
         .source(Source.fromEcrPublic(EcrPublicProps.builder()
                 .imageConfiguration(ImageConfiguration.builder().port(8000).build())
                 .imageIdentifier("public.ecr.aws/aws-containers/hello-app-runner:latest")
                 .build()))
         .vpcConnector(vpcConnector)
         .build();

  • Field Details

    • DEFAULT_CIDR_RANGE

      @Stability(Stable) public static final String DEFAULT_CIDR_RANGE
      The default CIDR range used when creating VPCs.

      This can be overridden using VpcProps when creating a VPCNetwork resource. e.g. new VpcResource(this, { cidr: '192.168.0.0./16' })

      Note this is specific to the IPv4 CIDR.

    • DEFAULT_SUBNETS

      @Stability(Stable) public static final List<SubnetConfiguration> DEFAULT_SUBNETS
      The default subnet configuration.

      1 Public and 1 Private subnet per AZ evenly split

    • DEFAULT_SUBNETS_NO_NAT

      @Stability(Stable) public static final List<SubnetConfiguration> DEFAULT_SUBNETS_NO_NAT
      The default subnet configuration if natGateways specified to be 0.

      1 Public and 1 Isolated Subnet per AZ evenly split

  • Constructor Details

    • Vpc

      protected Vpc(software.amazon.jsii.JsiiObjectRef objRef)

    • Vpc

      protected Vpc(software.amazon.jsii.JsiiObject.InitializationMode initializationMode)

    • Vpc

      @Stability(Stable) public Vpc(@NotNull software.constructs.Construct scope, @NotNull String id, @Nullable VpcProps props)
      Vpc creates a VPC that spans a whole region.

      It will automatically divide the provided VPC CIDR range, and create public and private subnets per Availability Zone. Network routing for the public subnets will be configured to allow outbound access directly via an Internet Gateway. Network routing for the private subnets will be configured to allow outbound access via a set of resilient NAT Gateways (one per AZ).

      Parameters:
      scope - This parameter is required.
      id - This parameter is required.
      props -

    • Vpc

      @Stability(Stable) public Vpc(@NotNull software.constructs.Construct scope, @NotNull String id)
      Vpc creates a VPC that spans a whole region.

      It will automatically divide the provided VPC CIDR range, and create public and private subnets per Availability Zone. Network routing for the public subnets will be configured to allow outbound access directly via an Internet Gateway. Network routing for the private subnets will be configured to allow outbound access via a set of resilient NAT Gateways (one per AZ).

      id - This parameter is required.

  • Method Details

    • fromLookup

      @Stability(Stable) @NotNull public static IVpc fromLookup(@NotNull software.constructs.Construct scope, @NotNull String id, @NotNull VpcLookupOptions options)
      Import an existing VPC by querying the AWS environment this stack is deployed to.

      This function only needs to be used to use VPCs not defined in your CDK application. If you are looking to share a VPC between stacks, you can pass the Vpc object between stacks and use it as normal.

      Calling this method will lead to a lookup when the CDK CLI is executed. You can therefore not use any values that will only be available at CloudFormation execution time (i.e., Tokens).

      The VPC information will be cached in cdk.context.json and the same VPC will be used on future runs. To refresh the lookup, you will have to evict the value from the cache using the cdk context command. See https://docs.aws.amazon.com/cdk/latest/guide/context.html for more information.

      Parameters:
      scope - This parameter is required.
      id - This parameter is required.
      options - This parameter is required.

    • fromVpcAttributes

      @Stability(Stable) @NotNull public static IVpc fromVpcAttributes(@NotNull software.constructs.Construct scope, @NotNull String id, @NotNull VpcAttributes attrs)
      Import a VPC by supplying all attributes directly.

      NOTE: using fromVpcAttributes() with deploy-time parameters (like a Fn.importValue() or CfnParameter to represent a list of subnet IDs) sometimes accidentally works. It happens to work for constructs that need a list of subnets (like AutoScalingGroup and eks.Cluster) but it does not work for constructs that need individual subnets (like Instance). See https://github.com/aws/aws-cdk/issues/4118 for more information.

      Prefer to use Vpc.fromLookup() instead.

      Parameters:
      scope - This parameter is required.
      id - This parameter is required.
      attrs - This parameter is required.
