Description

Service spec.type should not be NodePort. This rule flags Kubernetes Service resources where spec.type is set to NodePort, because exposing node ports can bypass load balancers and introduce security and networking risks. The rule returns the following attributes to identify the affected resource and the mismatch: documentId, resourceType, resourceName, searchKey, issueType, keyExpectedValue, keyActualValue.

Compliant Code Examples

resource "kubernetes_service" "example2" {
  metadata {
    name = "terraform-example"
  }
  spec {
    selector = {
      app = kubernetes_pod.example.metadata.0.labels.app
    }
    session_affinity = "ClientIP"
    port {
      port        = 8080
      target_port = 80
    }

    type = "LoadBalancer"
  }
}

Non-Compliant Code Examples

resource "kubernetes_service" "example" {
  metadata {
    name = "terraform-example"
  }
  spec {
    selector = {
      app = kubernetes_pod.example.metadata.0.labels.app
    }
    session_affinity = "ClientIP"
    port {
      port        = 8080
      target_port = 80
    }

    type = "NodePort"
  }
}
