Terraform Provider config inside child module - terraform

Question

I’m trying to create modules that will handle helm deployments. the structure goes like this
root module - call helm-traefik module
there’s an input (cluster name) that will be used to fetch data sources for the provider config inside the helm child module.
child module - helm-traefik
main tf. - call helm module
variables.tf
values.yaml
child module - helm
providers.tf - both provider config for kubernetes and helm are using kubelogin for authentication
datasources.tf
main.tf - helm_release
variables.tf
The issue is that I’m getting an error with tf plan and it says that Kubernetes cluster is unreachable. I’ve been reading docs regarding providers and I think the reason why I’m getting errors is that I don’t have the provider config for Kubernetes and helm in the root module level. Any feasible solution for this use case? I want to have a separation between the helm module in a way it can be consumed regardless of the helm chart to be deployed.
Also, If I put the provider config from the child module to the root module, that would mean I need to create a provider config for each cluster I want to manage.
on helm - child module, this is how I generate the provider config
datasources.tf
locals {
# The purpose of the cluster.
purpose = split("-", "${var.cluster_name}")[0]
# The network environment of the cluster.
customer_env = split("-", "${var.cluster_name}")[2]
}
data "azurerm_kubernetes_cluster" "cluster" {
resource_group_name = "rg-${local.purpose}-${local.customer_env}-001"
name = "aks-${local.purpose}-${local.customer_env}"
}
provider.tf
provider "kubernetes" {
host = data.azurerm_kubernetes_cluster.cluster.kube_config.0.host
cluster_ca_certificate = base64decode(data.azurerm_kubernetes_cluster.cluster.kube_config.0.cluster_ca_certificate)
exec {
api_version = "client.authentication.k8s.io/v1beta1"
command = "kubelogin"
args = [
"get-token",
"--login", "spn",
"--environment", "AzurePublicCloud",
"--server-id", "6dae42f8-4368-4678-94ff-3960e28e3630",
"--tenant-id", data.azurerm_client_config.current.tenant_id,
"--client-id", data.azurerm_client_config.current.client_id,
"--client-secret", data.azurerm_key_vault_secret.service_principal_key.value,
]
}
}
