【CKA模拟题】Ingress新手必看，全面了解Ingress的基础操作

题干

For this question, please set this context (In exam, diff cluster name)

kubectl config use-context kubernetes-admin@kubernetes

There exists a deployment named nginx-deployment exposed through a service called nginx-service . Create an ingress resource named nginx-ingress-resource to efficiently distribute incoming traffic with the following settings: pathType: Prefix , path: /shop , Backend Service Name: nginx-service , Backend Service Port: 80 , ssl-redirect should be configured as false .

存在一个名为nginx-deployment的部署，它通过一个名为nginx-service的服务公开。创建一个名为nginx-ingress-resource的入口资源，通过以下设置来高效地分配传入的流量:pathType: Prefix, path: /shop，后端服务名称:nginx-service，后端服务端口:80,ssl-redirect应该配置为false。

解题思路

1. 部署Ingress

kubectl apply -f \
> https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.10.0/deploy/static/provider/cloud/deploy.yaml

2. 参考官方文档Ingress编写nginx-ingress-resource资源清单，内容如下

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx-ingress-resource
  annotations:
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /shop
        pathType: Prefix
        backend:
          service:
            name: nginx-service
            port:
              number: 80

• ingressClassName: 通过kubectl get  ingressclasses获取

3. 提交资源nginx-ingress-resource资源清单

kubectl apply -f nginx-ingress-resource.yaml

4. 验证结果

controlplane $ k get ingress
NAME                     CLASS   HOSTS   ADDRESS   PORTS   AGE
nginx-ingress-resource   nginx   *                 80      27m
