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 http://api.example.com 访问代理在我的浏览器中，但如果我通过 nginx 代理通行证则不会。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。

例子:
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-network，然后 nginx 将能够解析 dns“mysite”。
