如何将 Nginx IP 附加到 Kubernetes Nginx Ingress Controller 中的 X-Forwarded-For

我想知道“如何将 Nginx IP 附加到 X-Forwarded-For”

我在 Ingress 注释中添加了片段。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: ing
  annotations:
    nginx.ingress.kubernetes.io/configuration-snippet: |
      proxy_set_header X-Forwarded-For "$remote_addr, $server_addr";

但它似乎在 nginx.conf 中进行了双重设置。

    proxy_set_header X-Forwarded-For        $remote_addr;
...
    proxy_set_header X-Forwarded-For "$remote_addr, $server_addr";

所以我的后端服务器将得到两个X-Forwarded-For

有人知道“如何禁用 Nginx Ingress Controller 生成的 proxy_set_header 部分”吗？

        proxy_set_header X-Request-ID           $req_id;
        proxy_set_header X-Real-IP              $remote_addr;

        proxy_set_header X-Forwarded-For        $remote_addr;

        proxy_set_header X-Forwarded-Host       $best_http_host;
        proxy_set_header X-Forwarded-Port       $pass_port;
        proxy_set_header X-Forwarded-Proto      $pass_access_scheme;

        proxy_set_header X-Scheme               $pass_access_scheme;

接受的答案不管用为我。您只需要添加以下内容注解 to the ingress object;

nginx.ingress.kubernetes.io/configuration-snippet: |
      more_set_headers "X-Forwarded-For $http_x_forwarded_for";

供测试用;
