permanent_Nginx Ingress配置重定向规则

在配置Nginx Ingress时，我们可以使用rewrite指令来重定向请求，以下是一个简单的示例：

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。

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，这通常在Ingress控制器的部署配置中完成，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/kubernetesingresscontroller/nginxingresscontroller:0.26.1
        args:
          /nginxingresscontroller
          configmap=$(POD_NAMESPACE)/nginxconfiguration
          tcpservicesconfigmap=$(POD_NAMESPACE)/tcpservices
          udpservicesconfigmap=$(POD_NAMESPACE)/udpservices
          publishservice=$(POD_NAMESPACE)/ingressnginx
        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: nginxconfiguration
data:
  httpredirectcode: "301"
  useforwardedheaders: "true"
  servertokens: "false"
  enablesslpassthrough: "true"
  logformatjson: "true"
  logformatsyslog: |
    {"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}
  proxysetheaderxrealip: "true"
  proxysetheaderxforwardedfor: "true"
  proxysetheaderxforwardedproto: "true"

  limitratesrc: "500k"
  limitratesrcburst: "1000"
  limitratesrcnodelay: "false"
  limitratesrcset: "500k"

  limitratesrcsetnodelay: "false"
