docker - Docker Nginx 主机无法解析

Question

我正在尝试连接到已设置的docker中的proxypass，但我不断收到：

8#8: *1 api.example.local could not be resolved (3: Host not found)

我可以通过在浏览器中访问http://api.example.com来访问代理，但如果我通过 nginx 代理通行证则无法访问。我的nginx如下，请注意：

• 禁用 ipv6

• 我正在解决 127.0.0.11

  server {
      listen   80;
      server_name  api.example.local;
      resolver 127.0.0.11 ipv6=off;
  
  location / {
      root    /code/api/public_html/;
      index  index.php index.html index.htm;
      try_files $uri $uri/ /index.php?rt=$uri&$args;
  }
  
  
  location ~ \.php$ {
      root    /code/api/public_html/;
      fastcgi_pass php:9000;
      fastcgi_index  index.php;
      #fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include fastcgi_params;
      fastcgi_param  PATH_INFO        $fastcgi_path_info;
      fastcgi_param  ENV  development;
      fastcgi_param HTTPS off;
      fastcgi_read_timeout 9600;
  }
  

  }

  server {
      index index.php index.html;
      server_name www.example.local;
      resolver 127.0.0.11 ipv6=off;
      error_log  /var/log/nginx/error.log;
      access_log /var/log/nginx/access.log;
      root /code/main/public_html;
  
  location / {
      root    /code/main/public_html/;
      index  index.php index.html index.htm;
      try_files $uri $uri/ /index.php?rt=$uri&$args;
  }
  
  location /api {
      resolver 127.0.0.11 ipv6=off;
      proxy_pass_header  Set-Cookie;
      proxy_pass_header  P3P;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Fowarded-Host $host;
  
  
  
  set $upstream api.example.local;
  
      proxy_pass http://$upstream;
      proxy_connect_timeout 60;
      proxy_redirect     off;
  }
  
  location ~ \.php$ {
      root    /code/main/public_html/;
      fastcgi_pass php:9000;
      fastcgi_index  index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include fastcgi_params;
      fastcgi_param  PATH_INFO        $fastcgi_path_info;
      fastcgi_param  ENV      development;
      fastcgi_param HTTPS off;
      fastcgi_read_timeout 300;
  }
  

  }

我的 /etc/hosts 中也有域。操作系统是 Ubuntu 18.04。

127.0.0.1       localhost
127.0.1.1       my-comp

127.0.0.1       www.example.local
127.0.0.1       api.example.local

我做错了什么？

nginx 容器和上游服务器需要在同一个 docker 网络上。

示例：假设 nginx 容器在网桥上暴露了 443 端口，创建一个名为 nginx-network 的 docker 网络并将其加入该网络。假设上游服务器是一个名为“mysite”的容器，将该容器加入 nginx 网络，然后 nginx 将能够解析 dns 'mysite'。
