Nifi on docker behind nginx processor configure not opening

Question

按照指南（https://michalklempa.com/2019/04/nifi-registry-nginx-proxy-tls-basic-auth/）设置 nginx 基本身份验证，但是我没有为 nifi-registry 设置代理，而是为 nifi 设置了它。 Auth 正在工作并且页面可以访问，但处理器配置 window 不知何故无法打开。这个问题是由于 nginx 造成的，因为通过 HTTP 暴露的端口直接访问 nifi 是有效的，只是不在 nginx 代理之后。

以下是我使用的配置：

server {
  listen 9988 ssl;

  root /usr/share/nginx/html;

  index index.html;

  server_name _;

  ssl_certificate /etc/nginx/server_cert.pem;
  ssl_certificate_key /etc/nginx/server_key.pem;

  ssl_client_certificate /etc/nginx/client_cert.pem;
  ssl_verify_client optional;

  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  # enables server-side protection from BEAST attacks
  ssl_prefer_server_ciphers on;

  # Disabled insecure ciphers suite. For example, MD5, DES, RC4, PSK
  ssl_ciphers "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4:@STRENGTH";

  # -!MEDIUM：exclude encryption cipher suites using 128 bit encryption.
  # -!LOW：   exclude encryption cipher suites using 64 or 56 bit encryption algorithms
  # -!EXPORT： exclude export encryption algorithms including 40 and 56 bits algorithms.
  # -!aNULL：  exclude the cipher suites offering no authentication. This is currently the anonymous DH algorithms and anonymous ECDH algorithms.
  # These cipher suites are vulnerable to a "man in the middle" attack and so their use is normally discouraged.
  # -!eNULL：exclude the "NULL" ciphers that is those offering no encryption.
  # Because these offer no encryption at all and are a security risk they are disabled unless explicitly included.
  # @STRENGTH：sort the current cipher list in order of encryption algorithm key length.

  location / {
    if ($ssl_client_verify = SUCCESS) {
      set $auth_basic off;
    }
    if ($ssl_client_verify != SUCCESS) {
      set $auth_basic "Restricted Content. Please provide Nifi Authentication:";
    }

    auth_basic $auth_basic;
    auth_basic_user_file /etc/nginx/nginx.htpasswd;

    proxy_pass    http://172.18.0.77:8181/; # actual container ip/port of nifi
    proxy_set_header   Host                 $host;
    proxy_set_header   X-Real-IP            $remote_addr;
    proxy_set_header   X-Forwarded-For      $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto    $scheme;
    proxy_set_header   X-Forwarded-User     $remote_user;
    proxy_set_header   Authorization        "";
    proxy_set_header   X-ProxyScheme        $scheme;
    proxy_set_header   X-ProxyHost          $hostname;
    proxy_set_header   X-ProxyPort          $server_port;
    proxy_set_header   X-ProxyContextPath   "/";
  }
}

我尝试为 X-ProxyHost 传递 nifi/host/nginx 的容器 ip，但它没有立即给出“无法与 nifi 通信”，而是旋转了一段时间并最终给出了相同的错误。这里需要修改什么？任何帮助将不胜感激。

这里是 nginx 菜鸟！在多次摆弄多个 ip/hostname 组合之后，我能够通过以下配置更改来修复它。必须将 nifi env 属性添加到 docker-compose:

environment:
  - NIFI_REMOTE_INPUT_HOST=<private ip of nifi container e.g. 172.18.0.77>
  - NIFI_WEB_PROXY_CONTEXT_PATH=/
  - NIFI_WEB_HTTP_HOST=<private ip of nifi container>
  - NIFI_WEB_HTTP_PORT=8181

对于 nginx 配置：将 proxy_set_header 修改为“localhost”（因为 nginx 服务器需要将 proxyHost 定义为环回服务器）：

proxy_set_header X-ProxyHost localhost;

希望这能帮助那些在同一条船上摸不着头脑的人:)
