  loki_iam_role_name           = "loki-${var.eks_cluster_id}"
  loki_compactor_iam_role_name = "loki-compactor-${var.eks_cluster_id}"
  grafana_iam_role_name        = "grafana-${var.eks_cluster_id}"

  loki_storage_s3_bucket_name = var.loki_storage_s3_bucket_name

  chart_version_loki_distributed = var.chart_version_loki_distributed
  chart_version_promtail         = var.chart_version_promtail
