Data Source: aws_vpc_ipam_pool_cidrs

aws_vpc_ipam_pool_cidrs provides details about an IPAM pool.

This resource can prove useful when an ipam pool was shared to your account and you want to know all (or a filtered list) of the CIDRs that are provisioned into the pool.

Example Usage

Basic usage:

data "aws_vpc_ipam_pool_cidrs" "c" {
  ipam_pool_id = data.aws_vpc_ipam_pool.p.id
}

data "aws_vpc_ipam_pool" "p" {
  filter {
    name   = "description"
    values = ["*mypool*"]
  }

  filter {
    name   = "address-family"
    values = ["ipv4"]
  }
}

Filtering:

data "aws_vpc_ipam_pool_cidrs" "c" {
  ipam_pool_id = "ipam-pool-123"
  filter {
    name   = "cidr"
    values = ["10.*"]
  }
}

locals {
  mycidrs = [for cidr in data.aws_vpc_ipam_pool_cidrs.c.ipam_pool_cidrs :
    cidr.cidr if
  cidr.state == "provisioned"]
}

resource "aws_ec2_managed_prefix_list" "pls" {
  name           = "IPAM Pool (${aws_vpc_ipam_pool.test.id}) Cidrs"
  address_family = "IPv4"
  max_entries    = length(local.mycidrs)

  dynamic "entry" {
    for_each = local.mycidrs
    content {
      cidr        = entry.value
      description = entry.value
    }
  }
}
