如何在本地环境中给 ingress 一个本地域名

Question

我使用

deployment.yml

和

service.yml

安装了 pod 和服务，如下所示。

deployment.yml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: apa000dep
spec:
  selector:
    matchLabels:
      app: apa000kube
  replicas : 3
  template:
    metadata:
      labels:
        app: apa000kube
    spec:
      containers:
        - name: apa000ex91
          image: httpd
          ports:
          - containerPort: 80
      

service.yml

apiVersion: v1
kind: Service
metadata: 
  name: apa000ser
spec:
  type: NodePort
  ports:
  - port: 8099
    targetPort: 80
    protocol: TCP
    nodePort: 30080
  selector:
    app: apa000kube

两者都很好，我可以直接访问 pod

localhost:30080

然后我安装了入口。

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  rules:
  - http:
      paths:
      - pathType: Prefix
        path: /*
        backend:
          service:
            name: apa000ser
            port:
              number: 8099

目前，没有主机名，

$kubectl get ingress
NAME              CLASS    HOSTS   ADDRESS   PORTS   AGE
example-ingress   <none>   *                 80      4m25s

所以，我安装了

ingress-nginx

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.2.0/deploy/static/provider/cloud/deploy.yaml

kubectl get pods -A
NAMESPACE              NAME                                         READY   STATUS             RESTARTS        AGE

那我怎么设置本地测试的域名呢？

是否应该在ingress.yml中设置域名？
