I'm trying to setup Azure Kubernetes Services with Terraform with the 'Azure Voting'-app.

I'm using the code mentioned below, however I keep getting the error on the Load Balancer: "Internal Server Error". Any idea what is going wrong here?

Seems like the Load Balancer to Endpoint (POD) is configured correclt,y thus not sure what is missing here.

main.tf

provider "azurerm" {
  features {}
}

data "azurerm_kubernetes_cluster" "aks" {
  name                = "kubernetescluster"
  resource_group_name = "myResourceGroup"
}

provider "kubernetes" {
  host = data.azurerm_kubernetes_cluster.aks.kube_config[0].host

  client_certificate     = base64decode(data.azurerm_kubernetes_cluster.aks.kube_config.0.client_certificate)
  client_key             = base64decode(data.azurerm_kubernetes_cluster.aks.kube_config.0.client_key)
  cluster_ca_certificate = base64decode(data.azurerm_kubernetes_cluster.aks.kube_config.0.cluster_ca_certificate)
}

resource "kubernetes_namespace" "azurevote" {
  metadata {
    annotations = {
      name = "azurevote-annotation"
    }

    labels = {
      mylabel = "azurevote-value"
    }

    name = "azurevote"
  }
}

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

    type = "LoadBalancer"
  }
}

resource "kubernetes_pod" "example" {
  metadata {
    name = "terraform-example"
    labels = {
      app = "azure-vote-front"
    }
  }

  spec {
    container {
        image = "mcr.microsoft.com/azuredocs/azure-vote-front:v1"
        name  = "example"
    }
  }
}

variables.tf

variable "prefix" {
    type = string
    default = "ab"
    description = "A prefix used for all resources in this example"
}

CodePudding user response：

It seems that your infrastructure setup is ok, the only thing is the application itself, you create only the front app, and you need to create the backend app to.

You can see the deployment examples here.

You also can see here the exception when you run the frontend without the backend.
