配置Ingress配置http代理：

# ingree-demo-http.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: slb-s1
  namespace: default
  annotations:
    # 因为安装traefik时候创建了 ingressClass 资源，因此不需要依赖注释中的 kubernetes.io/ingress.class
    # kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
  ingressClassName: traefik
  rules:
  - host: slb-s1-http.huanle.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: slb-s1
            port:
              name: http
