空地址kubernetes入口

我尝试在kubernetes群集上配置入口。我按照文档安装了入口控制器并运行了以下命令

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/baremetal/service-nodeport.yaml

在运行默认的http-backend和nginx-ingress-controller之后：

ingress-nginx   default-http-backend-846b65fb5f-6kwvp      1/1       Running   0          23h       192.168.2.28   node1
ingress-nginx   nginx-ingress-controller-d658896cd-6m76j   1/1       Running   0          6m        192.168.2.31   node1

我尝试测试入口，并部署了以下服务：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: echoserver-deploy
spec:
  replicas: 2
  selector:
    matchLabels:
      app: echo
  template:
    metadata:
      labels:
        app: echo
    spec:
      containers:
        - name: my-echo
          image: gcr.io/google_containers/echoserver:1.8
---
apiVersion: v1
kind: Service
metadata:
  name: echoserver-svc
spec:
  selector:
    app: echo
  ports:
    - protocol: TCP
      port: 8080
      targetPort: 8080

以及以下入口：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: happy-ingress
  annotations:
    INGRESS.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: happy.k8s.io
      http:
        paths:
          - path: /echoserver
            backend:
              serviceName: echoserver-svc
              servicePort: 8080

当我运行命令“ kubectl get ing”时，我收到：

NAME            HOSTS          ADDRESS   PORTS     AGE
happy-ingress   happy.k8s.io             80        14m

我没有解决ADDRESS，也无法弄清楚问题出在哪里，因为所有Pod都在运行。您能给我提示一下这个问题可能是什么吗？

谢谢

ingress addons创建入口规则之前，必须先通过命令启用。您还可以在执行任何其他命令之前启用它

$ minikube addons enable ingress
ingress was successfully enabled

等到吊舱启动并运行。您可以通过执行以下命令来检查并等待类似的输出

kubectl get pods -n kube-system | grep nginx-ingress-controller

nginx-ingress-controller-5984b97644-jjng2   1/1       Running   2          1h

因为Deployment您必须指定containerPort和并且Service必须指定http协议。

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: echoserver-deploy
spec:
  replicas: 2
  selector:
    matchLabels:
      app: my-echo
  template:
    metadata:
      labels:
        app: my-echo
    spec:
      containers:
        - name: my-echo
          image: gcr.io/kubernetes-e2e-test-images/echoserver:2.1
          ports:
          - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: echoserver-svc
spec:
  selector:
    app: my-echo
  ports:
  - protocol: TCP
    port: 80
    targetPort: 8080
    name: http

对于入口规则，将端口servicePort从8080 更改为默认的http端口80。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: happy-ingress
  annotations:
    INGRESS.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: happy.k8s.io
    http:
      paths:
      - path: /echoserver
        backend:
          serviceName: echoserver-svc
          servicePort: 80

现在应用这些文件并创建您的Pod，服务和入口规则。请稍等片刻，这将花费一些时间来获取您的入口规则的地址。 现在，您可以使用minikube ip地址访问您的服务，但不能按主机名访问。为此，您必须在/etc/hosts文件中添加主机和相应的IP地址。因此/etc/hosts，请在您喜欢的编辑器中打开文件，然后在下面的行中添加minikube的实际IP地址

 happy.k8s.io

现在，您可以使用主机名访问服务。验证以下命令

curl http://happy.k8s.io/echoserver
