Inventory Configuration with Terraform

In this section you will be creating the Terraform configuration for the Fabric Switches

Step 1 - Create modules/fabric/inventory.tf file

touch ~/workspace/ndfclab/terraform/modules/fabric/inventory.tf
code-server -r ~/workspace/ndfclab/terraform/modules/fabric/inventory.tf

To define the fabric switches for our lab, we will be using the ndfc_inventory_devices resource. This resource allows us to specify the devices that will be part of the fabric, including their roles and configurations. Notice that we are again leveraging several variables that have been defined in your variables.tf file.

The depends_on argument is used to ensure that the fabric is created before the inventory devices are processed. This is important because the inventory devices depend on the fabric being in place before they can be added.

resource "ndfc_inventory_devices" "nac_inventory_devices_1" {
  fabric_name                               = var.fabric_name
  auth_protocol                             = "md5"
  username                                  = "admin"
  password                                  = "cisco.123"
  max_hops                                  = 0
  set_as_individual_device_write_credential = false
  preserve_config                           = false
  save                                      = true
  deploy                                    = false
  retries                                   = 350
  retry_wait_timeout                        = 20
  devices = {
    (var.staging-spine1) = {
      role                    = "spine"
      discovery_type          = "discover"
      discovery_auth_protocol = "md5"
    }
    (var.staging-leaf1) = {
      role                    = "leaf"
      discovery_type          = "discover"
      discovery_auth_protocol = "md5"
    }
    (var.staging-leaf2) = {
      role                    = "leaf"
      discovery_type          = "discover"
      discovery_auth_protocol = "md5"
    }
  }

  depends_on = [
    ndfc_fabric_vxlan_evpn.nac_fabric1,
  ]
}

Step 2 - Close All Open VSCode Tabs for Next Terraform Section

In your VSCode application; on the keyword press Ctrl + K + W. This should close all open tabs to clear your workspace.
