Make Grafana admin credentials configurable

Im using the admin credentials to configure dashboards inside Grafana. Now i saw that the attributes "grafana_initial_admin_user" and "grafana_initial_admin_password" are marked as deprecated. How can i configure in the future the grafana instance through terraform if this will be removed?

output "cse_obs_grafana_username" {
  description = "Observability instance Grafana dashboard username"
  value       = stackit_observability_instance.kacls-monitoring.grafana_initial_admin_user
}

output "cse_obs_grafana_password" {
  description = "Observability instance Grafana dashboard password"
  value       = stackit_observability_instance.kacls-monitoring.grafana_initial_admin_password
  sensitive   = true
}

Proposed solution

Instead i suggest two new attributes "grafana_admin_password" and "grafana_admin_user" to set these data by the user.

resource "random_string" "username" {
  length  = 10
  special = false
  upper   = false
}

# Generiert ein hochsicheres Passwort
resource "random_password" "password" {
  length           = 32
  special          = true
  override_special = "!#$%&*()-_=+[]{}<>:?"
}

resource "stackit_observability_instance" "kacls-monitoring" {
  project_id = var.project_id
  name       = "kacls-monitoring-${var.cse_truncated_id}"
  plan_name  = var.obs_plan_name
  acl        = var.allowed_acl

  # C5 Audit compliance
  metrics_retention_days = 365
  alert_config           = var.cse_stage == "prod" ? local.alert_config_prod : local.alert_config_dev
  grafana_admin_user = "tech-user-${random_string.username.result}"
  grafana_admin_password = random_password.password.result
}

Alternative solutions (optional)

There are no alternative solutions. We need an account to configure Grafana through automation.
