this can help solve the mock_output issue since sometimes azurerm provider require the resource require to be valid and real

[gabo89]

this is not a issues but a solution to one of most biggest headaches i encounter in terragrunt, trying to mock values that area attached to data sources or to modules that expect real valid values in order to make it valid, is is related to mock_ outputs fake values , i encounter this during my terragrutn sessions and want to post this valuable solution to all

with this structure in my aks terraform module (check the depends on data structure)

variable "subnet_id" {
  type    = string
}

locals {
  # Split the ID and get the RG name at the right index
  vnet_rg = element(split("/", var.subnet_id), 4)
  vnet_name = element(split("/", var.subnet_id), 8)
}

data "azurerm_virtual_network" "aksvnet" {
  name                = local.vnet_name
  resource_group_name = local.vnet_rg
  depends_on = [azurerm_kubernetes_cluster.aks]
}

when i call the vnet dependnecy that is require for my aks , the plan phase will still show valid skipign the validation or check if the mocked values actually exists as resources

terraform {
  source = "../../../modules/kubernetes"
}


inputs = {
    location = include.env.locals.location
    workload =  include.env.locals.workload
    environment = include.env.locals.environment
    resource_group_id = dependency.rgaks.outputs.id
    subnet_id = dependency.vnet.outputs.subnetsid[2].id
    #runner_objectid set dynamically
}

dependency "vnet" {
  config_path = "../vnet"

  mock_outputs = {
    subnetsid = [
      { 
        id = "/subscriptions/11111111-2222-3333-4444-555555555555/resourceGroups/my-resource-group/providers/Microsoft.Network/virtualNetworks/my-vnet/subnets/one-subnet"
        name = "one-subnet"
      },
      { 
        id = "/subscriptions/11111111-2222-3333-4444-555555555555/resourceGroups/my-resource-group/providers/Microsoft.Network/virtualNetworks/my-vnet/subnets/two-subnet"
        name = "two-subnet"
      },
      { 
        id = "/subscriptions/11111111-2222-3333-4444-555555555555/resourceGroups/my-resource-group/providers/Microsoft.Network/virtualNetworks/my-vnet/subnets/three-subnet"
        name = "three-subnet"
      }
    ]
  }
}

apply this whenever you require it and remember to set the dependecy to a good value that is 100% related to the object itself beign created so the self reference make us ignore the strick checking in the mockign value

Thanks for creating this, @gabo89 ! I'm going to convert this to a discussion. That's a better place, in general, for conversations like this.
