Guys, I am trying to enable CI tasks in Azure DevOps and I am struggling with the Rover-Agent and the installed tflint tool in the AZDO Pipeline.
Does anyone have a working AZDO Pipeline definition running tflint successfully as an example?

Concerning enterprise landing zone (eslz) Could somebody explain the objects subscription_id_overrides_by_keys in subscription_id_overrides.tfvars to me.
I knew if i put a subscription id to subscription_id_overrides it will move it to the dependent management group. but what is the other key for.

Is there any development activity towards using the caf-terraform-landingzones module with a different backend, specifically Terraform Cloud? It seems to be pretty strongly joined to keeping state in a storage account via the launchpad azurerm backend.

Does the aztfmod/terraform-azurerm-caf super module contain any coverage for CDN profiles / endpoints?

Sorry if this blatantly obvious, I searched the repo and came up empty. I did get the static site stubbed, but want to add these resources as well. I can, of course, create these using the hashicorp/azurerm provider resources, but don't want to go outside of CAF if I can help it.

Hello. I am trying to use the module "resource_group_reused" to use an existing resource group vs the CAF module creating a new one for me, but running into some errors.

When I attempt to use it in my module I get the following error message:
Error: Unsupported argument

│ on main.tf line 37, in module "caf":
│ 37: resource_group_reused = {

│ An argument named "resource_group_reused" is not expected here.

In my code I am using it this way:

resource_group_reused = {
    rg = {
      name = var.resource_group_name
    }    
  }

I can successfully run this code block, but it creates a new resource group which is unwanted in my scenario:

 resource_groups = {
    rg = {
      name = local.resource_group_suffix
    }
  }

I found this resource_group_reused via this file: https://github.com/aztfmod/terraform-azurerm-caf/blob/master/resource_groups.tf

When I dig into the module it references it shows it using a data block which is desired vs the resource_group module which has a resource block

What am I doing wrong?

I have looked through a ton of the examples configurations in the github repo, but all of them seem to show examples of creating a new resource group. I can't find any examples for reusing a resource group that already exist.

Preview Module 5.5.0 - Hi community we are preparing release of module 5.5.0 which includes lot of improvements tracked under this milestone: https://github.com/aztfmod/terraform-azurerm-caf/milestone/6?closed=1. Almost everything is currently already in master branch. The main reason while we move to 5.5.x instead of 5.4.x is because we are introducing configuration aliases for virtual wan. Since provider configuration aliases were introduce in 0.15 we will need to drop support of Terraform 0.13 and 0.14. If you have a test environment, dont hesitate to test the module and give us feedbacks :)

@arnaudlh Best practices - Design pattern for referencing resources within CAF. For example:

private_dns_zone_id = try(
local.combined_objects_private_dns[each.value.private_dns_zone.lz_key][each.value.private_dns_zone.key].id,
local.combined_objects_private_dns[local.client_config.landingzone_key][each.value.private_dns_zone.key].id,
each.value.private_dns_zone.id,
null
)

Q1. For local & lower landingzones, we are using remote_objects = {}. But when do we used local.combined_objects vs local.<resource>?
Q2. Do we have a pattern that works for all scenarios? if the reference objects exists remote state or local state or local code block or external resource?
Q3. Are we supporting patterns such as vnet_key or switch to vnet { key="" lz_key=""} or support both?

Hello all, please forgive me if this has already been answered, but I am not finding in the examples the proper way to assign group owners... I have what I believe to be a legitimate configuration for the group:

azuread_groups = {
  architects = {
    name        = "AZ Group 1"
    description = "a super cool group"
    members = {
      user_principal_names = [
        "me@mycompany.com"
      ]
      group_names          = []
      object_ids           = []
      group_keys           = []

      service_principal_keys = []

    }
    owners = {
      user_principal_names = [
        "somebody_else@mycompany.com"
      ]
    }
    prevent_duplicate_name = true
  }
}

I can see that the member is getting applied correctly... but the owner object id in the plan is always the person etc. running the command... Anyone know what I am doing wrong here?

Thanks in advance!

Hello forum. I ran into a similar error like the one quoted here. The proposed solution by Luke to set azure_devops to "level1" and launchpad level to "lower" is incorporated in the new stable release. Has anyone experienced this? So I have been trying to 'customize' the starter template a bit to suit my needs by commenting out deployments to level3 and level4 which I do not need. I don't know if that has anything to do with this error. Thanks in advance for any tips or advice.

Evening all, hopefully someone can help me here. I've been using Terraform since the early days, probably started with v0.8 and loved it from day one. Deployed to AWS, Azure, VMWare and various other providers in all sorts of environments. So I'm very comfortable with it.

However, I'm struggling with the CAF. Not necessarily the actual module (it's complex but I know when I sit down and work through it I'll be fine). The issue is the actual implementation of it for real-world deployments. I'm really struggling following all the different repos and examples. Seems that there's always some other example or repo lurking that only serves to make me 'unlearn what I have just learnt' .

Is anyone aware of any good content that brings all this together and may help bridge the gap? I've not been able to put my finger on why I'm struggling having this all sink in.

Thanks all.....

Hello everyone, I have a question I hope someone can help me out with. Our environment does not use Rover.

I created the azuread group in a shared.tfstate file. But for different environments stored in env.tfstate I'd like to create the role assignments and pass the group_key. I want to reference this group through terraform_remote_state. I folowed the pattern in that doc: https://github.com/Azure/caf-terraform-landingzones/blob/master/documentation/code_architecture/service_composition.md
I added the data "terraform_remote..." and the local variable for azuread_groups in my main.tf. But when I try to reference the group in my env.tfvar it doesn't know about it. Any help would be appreciated.
Thanks in advance!

azuread_groups = {
  group_key = {
     id   = "data.terraform_remote_state.shared.outputs.objects.test.azuread_groups.group_key.id"
  }
}
#shared.tf

Hi, I've stood up the CAF demo environment through Level 2 and used the 100-single-linux-vm to stand a VM up in Level 3. I then wanted to tear down the level 3 vm, change some stuff and re-run it. When I ran the rover destroy process I received errors from KeyVault.

Error: purging of Secret "xyzzy-vm-examplevm1-ssh-public-key-openssh" (Key Vault "https://xyzzy-kv-vmlinuxakv.vault.azure.net/") : keyvault.BaseClient#PurgeDeletedSecret: Failure responding to request: StatusCode=403 -- Original Error: autorest/azure: Service returned an error.

Key Vault service will automatically purge it after the retention period has passed.\r\nVault: xyzzy-kv-vmlinuxakv;location=eastus2"

What is the proper recovery process when an error like this occurs? Also is this an error that should be reported somewhere?

Hi. Thanks for grate work with Enterprise Scale and CAF. When we use Enteprise Scale (ES) Management to deploy Log Analytics workspace and diagnostic_definitions, what would be the best /recomended aproach to deploy Azure CAF resources with this diagnostics profiles? I can't find any "link" between ES output and CAF input (or visa versa) to do this "out-of-the-box". I guess we can leave it to ES policies to deploy diagnostic profiles, but I think it would be better to do the linking directly when we create CAF resources. Apriciate your thoughts and recomendations?
