Rails 6 Docker + NGINX 为 webpacker 资产提供服务

如何解决Rails 6 Docker + NGINX 为 webpacker 资产提供服务

我正在尝试使用 Docker 部署我的 Rails 6.1.4 应用程序，并让 Nginx 处理资产服务。现在一切正常，除了当我尝试在 0.0.0.0:3000 上访问我的服务器时似乎找不到资产。

Nginx.conf

upstream app {
    server app:3000;
}

server {
    listen 80;
    server_name localhost;
    keepalive_timeout 5;
    
    root $RAILS_ROOT/public;

    access_log $RAILS_ROOT/log/access.log;
    error_log $RAILS_ROOT/log/error.log;

    location @app {
      proxy_redirect off;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_pass http://app;
    }

    location / {
      try_files $uri @app;
    }

    location ~ ^/(assets|packs)/ {
      gzip_static on;
      expires max;
      add_header Cache-Control public;
    }

    location = /favicon.ico {
      access_log off;
      log_not_found off;
    }
    
    location = /robots.txt  {
      access_log off;
      log_not_found off;
    }

    error_page 404 /404.html;
    location = /404.html {
    }

    error_page 500 502 503 504 /50x.html;
    location = /500.html {
    }
}

服务器启动正常，但我无法访问我的资产：

有谁知道这里出了什么问题？提前致谢！
