ACI / Terraform error: unknown property value

Lennart Jung — Tue, 13 Jul 2021 12:28:21 GMT

Hi *,

I am a rookie trying to get TF and ACI working - I've been trying to get my head around this for a cpuple of hours now and am still stuck. Maybe someone has an idea how to solve this error and point me into the right direction.

I have a set of servers that should be connected to their leafs (1201, 1202), going with a map holding all the details about the servers seemed to be a good idea to me.

my variables.tf looks like this (extracted the interesting bits):

variable "MAP_leaf_interface_profiles" {
 type = map(any)
 default = {
  "IP_LEAF-1201" = { name="IP_LEAF-1201", name_alias="", description="IP_LEAF-1201"}
  "IP_LEAF-1202" = { name="IP_LEAF-1202", name_alias="", description="IP_LEAF-1202"}
  "IP_LEAF-2401" = { name="IP_LEAF-2401", name_alias="", description="IP_LEAF-2401"}
  "IP_LEAF-2402" = { name="IP_LEAF-2402", name_alias="", description="IP_LEAF-2402"}
  "IP_LEAF-1201-1202" = { name="IP_LEAF-1201-1202", name_alias="", description="IP_LEAF-1201-1202"}
  "IP_LEAF-2401-2402" = { name="IP_LEAF-2401-2402", name_alias="", description="IP_LEAF-2401-2402"}
 }
}

variable "MAP_VxRail_hostnames-TEST" {
 type = map(any)
 default = {
 "XX123456789012-1201" = { hostname="XX123456789012", dc_location="DC1", VPC_PRD_DATA_interface="eth1/25", VPC_PRD_DATA_IP_tdn="uni/infra/accportprof-IP_LEAF-1201", VPC_PRD_DATA_IP="IP_LEAF-1201"},
 "XX123456789012-1202" = { hostname="XX123456789012", dc_location="DC1", VPC_PRD_DATA_interface="eth1/25", VPC_PRD_DATA_IP_tdn="uni/infra/accportprof-IP_LEAF-1202", VPC_PRD_DATA_IP="IP_LEAF-1202"}
 }
}

I am able to create the interface profiles "IP_LEAF-XXXX" with this snippet just fine:

resource "aci_leaf_interface_profile" "IP_LEAF-Profiles" {
 for_each = var.MAP_leaf_interface_profiles
  description = each.value.description
  name = each.value.name
}

As a next step I would like to create the acces_port_selector for each server with this piece of code:

resource "aci_access_port_selector" "IS_FRx-PRD_VxRail-DATA-SN" {
 for_each = var.MAP_VxRail_hostnames-TEST
  name = "IS_${each.value.dc_location}-PRD_VxRail-DATA-${each.key}"
  leaf_interface_profile_dn = "aci_leaf_interface_profile.IP_LEAF-Profiles.${each.value.VPC_PRD_DATA_IP}.id"
  description = "${each.value.hostname}"
  access_port_selector_type = "range"
}

which is failing big time with the following error:

│ Error: unknown property value aci_leaf_interface_profile.IP_LEAF-Profiles.IP_LEAF-1201.id/hports-IS_FR2-PRD_VxRail-DATA-XX123456789012-1201-typ-range, name dn, class infraHPortS [(Dn0)] Dn0=,
│
│ with aci_access_port_selector.IS_FRx-PRD_VxRail-DATA-SN["XX123456789012-1201"],
│ on main.tf line 67, in resource "aci_access_port_selector" "IS_FRx-PRD_VxRail-DATA-SN":
│ 67: resource "aci_access_port_selector" "IS_FRx-PRD_VxRail-DATA-SN" {
│

However when changing the following line (like hard-coding the tdn)

 leaf_interface_profile_dn = "${each.value.VPC_PRD_DATA_IP_tdn}"

everything just works fine:

aci_access_port_selector.IS_FRx-PRD_VxRail-DATA-SN["XX123456789012-1202"]: Creating...
aci_access_port_selector.IS_FRx-PRD_VxRail-DATA-SN["XX123456789012-1201"]: Creating...
aci_access_port_selector.IS_FRx-PRD_VxRail-DATA-SN["XX123456789012-1201"]: Creation complete after 1s [id=uni/infra/accportprof-IP_LEAF-1201/hports-IS_FR2-PRD_VxRail-DATA-XX123456789012-1201-typ-range]

Any idea how to fix this? I would like to avoid using the tDN in the map. Or is there even a better approach on doing this?

Hello Lennart!

We opened a forum in French with an ACI expert & VIP of the community Francesco Molino who answered your question. Please validate his reply as "accepted solution" in our forum and here!

Hi @Lennart Jung

You can replace the following line in your aci_access_port_selector resource

leaf_interface_profile_dn = "aci_leaf_interface_profile.IP_LEAF-Profiles.${each.value.VPC_PRD_DATA_IP}.id"

leaf_interface_profile_dn = aci_leaf_interface_profile.IP_LEAF-Profiles[each.value.VPC_PRD_DATA_IP].id

It should work depending on what you're trying to achieve as a goal.
