Terraform IPAM Provider

Dead simple IPAM provider, which stores IP pools and allocations in local file.

Works for those who'd like to use Git repository as Source of Truth for IP management.

Usage

provider "ipam" {
  file = "mycorp.ipam.json"
}

resource "ipam_pool" "internal_network" {
  cidr = "10.0.0.0/8"
}

#
# Availability zone
#

resource "ipam_allocation" "internal_az1" {
  pool_id = ipam_pool.internal.id
  size    = 10
}

# Also make it a pool to allocate from this particular IP range
resource "ipam_pool" "internal_az1" {
  cidr = ipam_allocation.internal_az1.cidr
}

# Single hosts


resource "ipam_allocation" "host_foo" {
  pool_id = ipam_pool.internal_az1.id
  # size defaults to 32, so may be omitted for single hosts
}

# ... and so on

Then you (your CI, preferrably) run terraform apply and commit resulting mycorp.ipam.json to the repo.

Features 😅

• Approvals powered with GitHub PRs or any platform of your choice
• Audit as simple as cat ipam.tf or terraform state
