日志未通过 Nginx 反向代理（Nginx 配置问题？）

Question

我们有 Node.js 个应用程序将日志发送到指向我的 Nginx 反向代理服务器的 URL。

我在 docker 容器中设置了 nginx 反向代理服务器，然后有一组用于 Fluentd、ElasticSearch 和 Kibana 的容器，用于接收、收集和显示这些日志。服务器上唯一保持打开的端口运行这些容器包括 nginx 反向代理是 8080(http) 和 443(https)。

正如我测试并确认的那样，日志是从应用程序正确生成的。另外，如果我在 docker 容器中没有 nginx 反向代理的情况下进行整个设置，那么一切都运行良好。

同样的 nginx 反向代理也被用于代理其他服务器，它们都运行良好。

唯一的问题似乎是 nginx 反向代理设置无法接收 Node.js 格式的 JSON 应用程序日志。但是 Http 和 https 请求正在通过。

我正在使用 LetsEncrypt 自动生成 SSL 证书并相应地自动生成此 nginx 配置。

我在这里附上了我的 nginx 配置文件：

# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  ''      $scheme;
}
# If we receive X-Forwarded-Port, pass it through; otherwise, pass along the
# server port the client connected to
map $http_x_forwarded_port $proxy_x_forwarded_port {
  default $http_x_forwarded_port;
  ''      $server_port;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  '' close;
}

map $scheme $proxy_x_forwarded_ssl {
  default off;
  https on;

Answer 1

所以这个配置文件随后在 http 块内的另一个 nginx 配置文件中被调用。我们不能在该块中接受 TCP 输入。所以我只需要为流创建另一个块，然后在其中为 tcp 连接放入必要的详细信息，现在一切都很好。
