public class VpcIpv4CidrBlockAssociation
extends com.pulumi.resources.CustomResource

Provides a resource to associate additional IPv4 CIDR blocks with a VPC. When a VPC is created, a primary IPv4 CIDR block for the VPC must be specified. The `aws.ec2.VpcIpv4CidrBlockAssociation` resource allows further IPv4 CIDR blocks to be added to the VPC. ## Example Usage

 
 package generated_program;
 
 import com.pulumi.Context;
 import com.pulumi.Pulumi;
 import com.pulumi.core.Output;
 import com.pulumi.aws.ec2.Vpc;
 import com.pulumi.aws.ec2.VpcArgs;
 import com.pulumi.aws.ec2.VpcIpv4CidrBlockAssociation;
 import com.pulumi.aws.ec2.VpcIpv4CidrBlockAssociationArgs;
 import java.util.ArrayList;
 import java.util.Arrays;
 import java.util.Map;
 import java.io.File;
 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var main = new Vpc("main", VpcArgs.builder()
             .cidrBlock("10.0.0.0/16")
             .build());
 
         var secondaryCidr = new VpcIpv4CidrBlockAssociation("secondaryCidr", VpcIpv4CidrBlockAssociationArgs.builder()
             .vpcId(main.id())
             .cidrBlock("172.20.0.0/16")
             .build());
 
     }
 }

## Import or or Using `pulumi import`, import `aws.ec2.VpcIpv4CidrBlockAssociation` using the VPC CIDR association ID and optionally the IPv4 IPAM pool ID and netmask length. For example: ```sh $ pulumi import aws:ec2/vpcIpv4CidrBlockAssociation:VpcIpv4CidrBlockAssociation example vpc-cidr-assoc-021e8461d70ed08be ``` or ```sh $ pulumi import aws:ec2/vpcIpv4CidrBlockAssociation:VpcIpv4CidrBlockAssociation example vpc-cidr-assoc-021e8461d70ed08be,ipam-pool-0a07c432810393463 ``` or ```sh $ pulumi import aws:ec2/vpcIpv4CidrBlockAssociation:VpcIpv4CidrBlockAssociation example vpc-cidr-assoc-021e8461d70ed08be,ipam-pool-0a07c432810393463,28 ```

```
public VpcIpv4CidrBlockAssociation(java.lang.String name)
```
    Parameters:
    
    name - The _unique_ name of the resulting resource.
  - VpcIpv4CidrBlockAssociation
```
public VpcIpv4CidrBlockAssociation(java.lang.String name,
                                   VpcIpv4CidrBlockAssociationArgs args)
```
    Parameters:
    
    name - The _unique_ name of the resulting resource.
    
    args - The arguments to use to populate this resource's properties.
  - VpcIpv4CidrBlockAssociation
```
public VpcIpv4CidrBlockAssociation(java.lang.String name,
                                   VpcIpv4CidrBlockAssociationArgs args,
                                   @Nullable
                                   com.pulumi.resources.CustomResourceOptions options)
```
    Parameters:
    
    name - The _unique_ name of the resulting resource.

  - cidrBlock
```
public com.pulumi.core.Output<java.lang.String> cidrBlock()
```
    Returns:
    
    IPv4 CIDR block for the VPC. CIDR can be explicitly set or it can be derived from IPAM using `ipv4NetmaskLength`.

```
    Returns:
    
    Region where this resource will be [managed](https://docs.aws.amazon.com/general/latest/gr/rande.html#regional-endpoints). Defaults to the Region set in the provider configuration.

```
    Returns:
    
    ID of the VPC to make the association with.
  - get

                                              VpcIpv4CidrBlockAssociationState state,
                                              @Nullable
                                              com.pulumi.resources.CustomResourceOptions options)
```
    Get an existing Host resource's state with the given name, ID, and optional extra properties used to qualify the lookup.
    
    Parameters:
    
    name - The _unique_ name of the resulting resource.
    
    id - The _unique_ provider ID of the resource to lookup.
