前提

Higress已经部署成功，参考 Higress部署

获取higress-gateway的端口

kubectl get svc -n higress-system

由于我们本地部署的K8S集群, 不支持LoadBalancer, 因此后续我们通过对应的 NodePort (1105)来访问gateway.

# 后续我们将通过该地址来访问gateway
# 注意, 在没有配置任何服务路由的时候, 直接请求该地址将不会返回任何值
curl 192.168.21.223:1105

部署Demo服务

示例服务监听8080端口, 并且返回 Hello World

yaml文件

demo_nginx.yaml

部署应用

kubectl apply -f demo_nginx.yaml

创建路由

方式一: 使用 Ingress CRD 创建路由

创建路由

# demo_nginx_ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: demo-nginx-ingress
spec:
  # 指定higress
  ingressClassName: higress
  rules:
    # 匹配任意host  
  - host: ""
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: demo-nginx-svc
            port:
              number: 8080

访问测试

使用浏览器访问 higress-gateway的NodePort. 返回了我们期望的 Hello World

方式二: 使用Higress Console 创建路由

获取 higress console访问地址

kubectl -n higress-system get svc higress-console

使用浏览器访问 NodeIP:39474来访问 Higress Console

创建路由

访问测试

使用浏览器访问 higress-gateway的NodePort. 返回了我们期望的 Hello World
