This module helps deploy AWS IPAM including IPAM Pools, Provisioned CIDRs, and can help with sharing those pools via AWS RAM.

Built to accommodate a wide range of use cases, this Terraform module can deploy both simple and complex Amazon Virtual Private Cloud (Amazon VPC) IP Address Manager (IPAM) configurations. It supports both symmetrically nested, multi-Region deployments (most common IPAM designs) as well as [asymmetically nested deployments](https://github.com/aws-ia/terraform-aws-ipam/blob/main/images/asymmetrical_example.png).

# Upgrade from v1 to v2
2+
3+
**NOTE: If you are not using public IPs there are no changes required to upgrade to v2.**
4+
5+
In order to support importing multiple public IPs into AWS IPAM, we have updated the variable `top_cidr_authorization_context`. This variable has been renamed to `top_cidr_authorization_contexts` (notice the `s`) which has a strict structure for to inform provision public cidrs into the top level pool.
6+
7+
8+
## Upgrade Guide
9+
10+
### HCL upgrade
11+
12+
Previously you could only specify the context for [1 public ip](https://github.com/aws-ia/terraform-aws-ipam/blob/991dcf02fd2175bd3a6b10a4ee61b01cf89f813d/examples/single_scope_ipv6/main.tf#L15C1-L18C4). This should now be updated to a list of maps that includes the corresponding cidr. See example below
13+
14+
15+
#### Before
16+
17+
```hcl
18+
top_cidr_authorization_context = {
19+
message = var.cidr_authorization_context_message
20+
signature = var.cidr_authorization_context_signature
21+
}
22+
```
23+
24+
#### After
25+
26+
```hcl
27+
top_cidr_authorization_contexts = [{
28+
cidr = var.cidr_authorization_context_cidr
29+
message = var.cidr_authorization_context_message
30+
signature = var.cidr_authorization_context_signature
31+
}]
32+
```
33+
34+
**IMPORTANT: Each `top_cidr_authorization_contexts[#].cidr` must have a corresponding matching reference in the `top_cidr` list.**

## Multiple Scopes
3+
4+
There are several reasons you may want to populate multiple IPAM scopes:
5+
6+
- Public & Private scope
7+
- IPv4 + IPv6
8+
- Overlapping IPv4 ranges
9+
10+
This example shows you how to build scopes for 2 overlapping IPv4 ranges that you want IPAM to manage. You do this by:
11+
12+
1. invoke module to build IPAM + ipv4 pool\_configuration
13+
2. create a new private scope on the IPAM built in step 1
14+
3. invoke module with `create_ipam = false` and pass in the new scope id created
15+
16+
For IPv4 + IPv6, skip step 2. Reference the `public_default_scope_id` from the ipam in step 1 instead of creating a new scope.
