IPAMAllocation

The IPAMAllocation resource allows you to manage IP address allocations within AWS EC2 using the AWS IP Address Manager (IPAM). For more details, refer to the AWS EC2 IPAMAllocations documentation.

Minimal Example

Create a basic IPAM allocation with required properties and a common optional description.

import AWS from "alchemy/aws/control";

const basicIpamAllocation = await AWS.EC2.IPAMAllocation("basicIpamAllocation", {
  IpamPoolId: "ipam-pool-12345678", // Replace with a valid IPAM pool ID
  Cidr: "10.0.0.0/24", // Allocating a CIDR block
  Description: "Basic IPAM allocation for development purposes"
});

Advanced Configuration

Configure an IPAM allocation with a specific netmask length to control the size of the CIDR block.

const advancedIpamAllocation = await AWS.EC2.IPAMAllocation("advancedIpamAllocation", {
  IpamPoolId: "ipam-pool-87654321", // Replace with a valid IPAM pool ID
  Cidr: "10.0.1.0/24",
  NetmaskLength: 24,
  Description: "Advanced IPAM allocation with specific netmask length"
});

Adoption of Existing Resources

If you want to adopt an existing IPAM allocation instead of failing when it already exists, you can enable the adoption feature.

const adoptedIpamAllocation = await AWS.EC2.IPAMAllocation("adoptedIpamAllocation", {
  IpamPoolId: "ipam-pool-11223344", // Replace with a valid IPAM pool ID
  Cidr: "10.0.2.0/24",
  adopt: true, // Enables adoption of existing resources
  Description: "Adopted IPAM allocation from existing resources"
});
