I’m working on a project using Terraform, Docker, and Minikube to deploy a web application. My setup includes the following:

A Dockerfile to build my web application:

FROM nginx:latest

COPY . /usr/share/nginx/html

EXPOSE 80

A Terraform configuration to deploy the application to Minikube:

terraform {
  required_providers {
    kubernetes = {
      source  = "hashicorp/kubernetes"
      version = ">= 2.11.0"
    }
  }
}

provider "kubernetes" {
  host                   = "https://192.168.49.2:8443"
  cluster_ca_certificate = file("/home/pawel/.minikube/ca.crt")
  client_certificate     = file("/home/pawel/.minikube/profiles/minikube/client.crt")
  client_key             = file("/home/pawel/.minikube/profiles/minikube/client.key")
}

resource "kubernetes_deployment" "app" {
  metadata {
    name = "app-deployment"
    labels = {
      app = "my-app"
    }
  }

  spec {
    replicas = 1

    selector {
      match_labels = {
        app = "my-app"
      }
    }

    template {
      metadata {
        labels = {
          app = "my-app"
        }
      }

      spec {
        container {
          name  = "my-app-container"
          image = "todo-app"
          port {
            container_port = 80
          }
        }
      }
    }
  }
}

resource "kubernetes_service" "app_service" {
  metadata {
    name = "app-service"
  }

  spec {
    selector = {
      app = "my-app"
    }

    port {
      port        = 80
      target_port = 80
    }

    type = "NodePort"
  }
}

resource "kubernetes_ingress_v1" "app_ingress" {
  metadata {
    name = "app-ingress"
    annotations = {
      "nginx.ingress.kubernetes.io/rewrite-target" = "/"
    }
  }

  spec {
    rule {
      host = "my-app.local"

      http {
        path {
          path = "/"
          path_type = "Prefix"

          backend {
            service {
              name = kubernetes_service.app_service.metadata[0].name
              port {
                number = 80
              }
            }
          }
        }
      }
    }
  }
}

The problem I’m facing is that after running terraform init and terraform apply, everything seems to execute without errors. However it doesn’t show my app that I’ve created in HTML,CSS and JS instead it shows Welcome to nginx!, but when I try opeining my page in docker it is working perfectly.
My Minikube setup also appears to be working:

minikube status:

minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

kubectl config get-contexts shows the correct context:

objectivec
CURRENT   NAME       CLUSTER    AUTHINFO   NAMESPACE
 1.         minikube   minikube   minikube   default

kubectl get nodes works as expected:

NAME       STATUS   ROLES           AGE   VERSION
minikube   Ready    control-plane   22h   v1.31.0

What I’ve tried:

• Ensured Minikube is running (minikube status).
• Switched to the correct context (minikube kubectl — config use-context minikube).
• Verified kubectl get nodes works fine.
• Attempted to run kubectl commands directly via Minikube:
• Verified the Minikube server is reachable:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "forbidden: User "system:anonymous" cannot get path "/"",
  "reason": "Forbidden",
  "details": {}
}
