在配置Nginx Ingress时，我们可以使用rewrite指令来重定向请求。

1、我们需要创建一个Ingress资源，在这个资源中，我们将定义一个规则，该规则将匹配所有的HTTP请求，并将它们重定向到另一个URL。

以下是一个示例：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingressredirect
spec:
  rules:
  - host: example.com
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: myservice
            port:
              number: 80

2、我们需要在Ingress控制器的配置文件中定义重定向规则。以下是一个使用Nginx Ingress控制器的示例：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginxingresscontroller
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginxingress
  template:
    metadata:
      labels:
        app: nginxingress
    spec:
      containers:
      - name: nginxingresscontroller
        image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.26.1
        args:
          - /nginx-ingress-controller
          - configmap=$(POD_NAMESPACE)/nginx-configuration
          - tcpservicesconfigmap=$(POD_NAMESPACE)/tcp-services
          - udpservicesconfigmap=$(POD_NAMESPACE)/udp-services
          - publish-service=$(POD_NAMESPACE)/ingress-nginx
        env:
          - name: POD_NAME
            valueFrom:
              fieldRef:
                fieldPath: metadata.name
          - name: POD_NAMESPACE
            valueFrom:
              fieldRef:
                fieldPath: metadata.namespace
        ports:
        - name: http
          containerPort: 80
        - name: https
          containerPort: 443

3、我们需要在ConfigMap中定义重定向规则。以下是一个示例：

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-configuration
data:
  http-redirect-code: "301"
  use-forwarded-headers: "true"
  server-tokens: "false"
  enable-ssl-passthrough: "true"
  log-format-json: "true"
  log-format-syslog: |
    {"time": "$time_iso8601", "remote_addr": "$remote_addr", "proxy_add_x_forwarded_for": "$proxy_add_x_forwarded_for", "request_id": "$req_id", "remote_user": "$remote_user", "bytes_sent": $bytes_sent, "request_time": $request_time, "status": $status, "host": "$host", "url": "$uri", "request_length": $request_length, "http_referer": "$http_referer", "http_user_agent": "$http_user_agent", "upstream_response_time": $upstream_response_time}
  proxy-set-header-x-real-ip: "true"
  proxy-set-header-x-forwarded-for: "true"
  proxy-set-header-x-forwarded-proto: "true"
  proxy-set-header-host: "true"
  proxy-set-header-from: "true"
  proxy-set-header-referer: "true"
  proxy-set-header-user-agent: "true"
  proxy-connect-timeout: "1800"
  proxy-read-timeout: "1800"
  proxy-send-timeout: "1800"

  gzip-min-length: "1000"
  gzip-comp-level: "6"
  gzip-disable: "false"
  gzip-vary: "Accept-Encoding"
  gzip-proxied: "any"
  limit-conn-zone-variable: "$binary_remote_addr"
  limit-conn-zone: "addr"
  limit-conn: "10"
  limit-rate-after: "10m"
  limit-rate: "500k"
  limit-rate-burst: "1000"
  limit-rate-conn: "500k"
  limit-rate-conn-burst: "1000"
  limit-rate-no-delay: "false"
  limit-rate-set: "500k"
  limit-rate-src: "500k"
  limit-rate-src-burst: "1000"
  limit-rate-src-no-delay: "false"
  limit-rate-src-set: "500k"
  limit-rate-src-set-burst: "1000"
  limit-rate-src-set-no-delay: "false"
  limit-rate-src-set-src: "500k"
  limit-rate-src-set-src-burst: "1000"
  limit-rate-src-set-src-no-delay: "false"
  limit-rate-src-set-src-set: "500k"
  limit-rate-src-set-src-set-burst: "1000"
  limit-rate-src-set-src-set-no-delay: "false"
  limit-rate-src-set-src-set-src: "500k"
  limit-rate-src-set-src-set-src-burst: "1000"
  limit-rate-src-set-src-set-src-no-delay: "false"
  limit-rate-src-set-src-set-src-set: "500k"
  limit-rate-src-set-src-set-src-set-burst: "1000"
  limit-rate-src-set-src-set-src-set-no-delay: "false"
  limit-rate-src-set-src-set-src-set-src: "500k"
  limit-rate-src-set-src-set-src-set-src-burst: "1000"
  limit-rate-src-set-src-set-src-set-src-no-delay: "false"
  limit-rate-src-set-src-set-src-set-src-set: "500k"
  limit-rate-src-set-src-set-src-set-src-set-burst: "1000"
  limit-rate-src-set-src-set-src-set-src-set-no-delay: "false"
  limit-rate-src-set-src-set-src-set-src-set-src: "500k"
  limit-rate-src-set-src-set-src-set-src-set-src-burst: "1000"
  limit-rate-src-set-src-set-src-set-src-set-src-no-delay: "false"
