Nginx 配置在生产环境中有效,但在 docker 中无效

Nginx 配置在生产环境中有效,但在 docker 中无效

我一直在努力将我们的生产环境 docker 化,它由一个 React 前端组成,该前端会向 Nginx 服务器发出 API 调用。Nginx 服务器将所有请求反向代理到 ASP .NET Core 应用程序。我已设法使后端映像(.NET 和数据库)通过 docker-compose 正常工作和通信,但现在我试图绑定 Nginx,但它无法正常工作。我的配置如下:

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events { worker_connections 1024; }

http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;

    # docker provides 'app' network address for api image
    upstream app_servers {
        server api:8080;
    }

    server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name _;
        return 301 https://$host$request_uri;
    }

    server {

        # SSL configuration
        listen 443 ssl default_server;
        listen [::]:443 ssl default_server;

        ssl_certificate /etc/nginx/server.crt;
        ssl_certificate_key /etc/nginx/server.key;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name localhost;

        location /ver {
            proxy_pass   http://app_servers/api/version;
            proxy_set_header Host $host;
        }
        location / {
            if ($request_method = OPTIONS ) {
                add_header 'Access-Control-Allow-Origin' '*' always; 
                add_header Access-Control-Allow-Methods "POST, OPTIONS";
                add_header Access-Control-Allow-Headers "Accept, Cache-Control, x-csrf-token, Authorization, Content-Type";
                add_header Content-Length 0;
                add_header Content-Type text/plain;
                return 200;
            }    

            add_header 'Access-Control-Allow-Origin' '*' always;


            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-Host $server_name;

            proxy_pass         http://app_servers/graphql;
            # 
            #proxy_redirect     off;

            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
        }
    }
}

此配置与生产服务器之间的唯一区别是,在生产中,proxy_pass目标是 127.0.0.1 而不是 app_servers,并且服务器名称是实际的服务器名称而不是 localhost。主机名api来自 docker-compose 中的服务定义。

我遇到的情况是,我可以成功访问 /ver 端点,但任何其他应路由到 api:8080/graphql 的请求都会导致 404。但是,我可以轻松连接到使用 GraphQL 游乐场公开 8080 的 docker 容器并发出请求。

任何见解都将不胜感激,我不是 100% 确信这是一个 Nginx 问题,但所有证据都指向这一点。

看来解决方案是删除以下几行:

try_files $uri $uri/ =404;
proxy_set_header   Host $host;
