# Net Address Reservation Module

This module allows reserving Compute Engine external, global, and internal addresses.

## Examples

### External and global addresses

```hcl
module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  external_addresses = {
    nat-1      = var.region
    vpn-remote = var.region
  }
  global_addresses = ["app-1", "app-2"]
}
# tftest modules=1 resources=4
```

### Internal addresses

```hcl
module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  internal_addresses = {
    ilb-1 = {
      purpose    = "SHARED_LOADBALANCER_VIP"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
    ilb-2 = {
      address    = "10.0.0.2"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
  }
}
# tftest modules=1 resources=2
```

### PSA addresses

```hcl
module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  psa_addresses = {
    cloudsql-mysql = {
      address       = "10.10.10.0"
      network       = var.vpc.self_link
      prefix_length = 24
    }
  }
}
# tftest modules=1 resources=1
```

### PSC addresses

```hcl
module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  psc_addresses = {
    one = {
      address = null
      network = var.vpc.self_link
    }
    two = {
      address = "10.0.0.32"
      network = var.vpc.self_link
    }
  }
}
# tftest modules=1 resources=2
```
