我学习本教程是为了了解反向代理https://www.youtube.com/watch?v=ZmH1L1QeNHk&t=227s
我运行这个Docker图像

sudo docker run -d --name nginx-base -p 80:80 nginx:latest

我可以编辑默认的.conf文件

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    location /test {
        proxy_pass http://localhost:8086/test;
    }

    location /home {
        proxy_pass http://localhost:3000;
    }

   location /home/auth {
        proxy_pass http://localhost:3000/auth;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
    
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
    
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

当我进入http：//localhost/时，我会看到Nginx欢迎屏幕
但当我尝试访问http：//localhost/test或http：//localhost/home时

此外，我还可以访问localhost:3000和localhost:8086/test
不知道为什么nginx抛出502，我错过了任何配置？
