使用 minikube 创建入口部署

Question

我正在通过 this 教程在 minikube 上创建部署和入口控制器。当我按照教程中的说明跑步时，

curl --resolve "hello-world.info:80:$( minikube ip )" -i http://hello-world.info

我只是得到

HTTP/1.1 503 Service Temporarily Unavailable

。

这是我的部署、服务、入口和自定义文件：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: example-deployment
  labels:
    app: example
spec:
  replicas: 2
  selector:
    matchLabels:
      app: example
  template:
    metadata:
      labels:
        app: example
    spec:
      containers:
      - name: nginx
        image: localhost:5000/example-app:latest
        ports:
        - name: web
          containerPort: 80

apiVersion: v1
kind: Service
metadata:
  name: example
spec:
  ports:
    - name: web
      port: 80
      targetPort: web
  selector:

    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: example
            port:
              number: 80

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
metadata:
  name: arbitrary

# Example configuration for the webserver
# at https://github.com/monopole/hello
commonLabels:
  app: example

resources:
- deployment.yaml
- service.yaml
- ingress.yaml

这是

kubectl get ingress

的输出：

NAME              CLASS   HOSTS              ADDRESS        PORTS   AGE
example-ingress   nginx   hello-world.info   192.168.49.2   80      3m29s

这是

kubectl get services

的输出：

kubectl get services
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)   AGE
example      ClusterIP   10.109.63.32   <none>        80/TCP    10m

如您所见，一切都已启动并正在运行。这是我的 nginx：

[jenia@archlinux ibn-battuta]$ kubectl get pods -n ingress-nginx
NAME                                        READY   STATUS      RESTARTS   AGE
ingress-nginx-admission-create-fvj4v        0/1     Completed   0          3h37m
ingress-nginx-admission-patch-d4xfn         0/1     Completed   1          3h37m
ingress-nginx-controller-7799c6795f-7qgsr   1/1     Running     0          3h37m

这是 nginx 503 的日志：

192.168.49.1 - - [29/Aug/2023:01:11:43 +0000] "GET / HTTP/1.1" 503 190 "-" "curl/8.2.1" 79 0.000 [default-example-80] [] - - - - e03c2a5e71db02f27f1afca0905c6c36

如果有人可以帮助我，我将不胜感激。

您可以在您的服务中更新

targetPort

和

selector

并进行验证吗？

apiVersion: v1
kind: Service
metadata:
  name: example
spec:
  ports:
    - name: web
      port: 80
      targetPort: 80
  selector:
    app: example
