nginx 不会在 80 以外的端口上监听 docker 上的 pgadmin

Question

我的服务器上有几个项目正在运行，我无法使用端口 80。 在这个 Docker 中，除了 Pgadmin 之外，一切正常。无论我如何更改代码，我都会在 :8090/pgadmin/

中收到 502 错误或 404 错误

谁能指导我？

nginx.conf：

upstream app_server {
server gis_app:8095;
}
upstream pg_server {
    server gis_pgadmin:5555;
}

server {
    listen 8090;
    server_name localhost;
    client_max_body_size 200M;

    location / {
        proxy_pass http://app_server;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host:$server_port;
            proxy_redirect off;
    }

    location /static/ {
        alias /srv/gis/static/;
    }

    location /media/ {
        alias /srv/gis/media/;
    }

    location /pgadmin/ {
        proxy_pass http://pg_server;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_redirect off;
    }
}

docker-compose.yml：

networks:
  gis_nginx_network:
    driver: bridge
  gis_db_network:
    driver: bridge
  gis_redis_network:
    driver: bridge

volumes:

  gis_media_volume:
  gis_db_volume:

和 pgadmin 环境：

PGADMIN_DEFAULT_EMAIL=mail@info.com
PGADMIN_DEFAULT_PASSWORD=password
PGADMIN_LISTEN_PORT=5555

Answer 1

因为PGADMIN_LISTEN_PORT=5555 正在监听端口5555

所以gis_pgadmin 容器应该监听那个端口5555

Nginx 将从8090 转发 --> 5555

gis_pgadmin:
    image: dpage/pgadmin4
    container_name: gis_pgadmin
    depends_on:
      - gis_db
    ports:
    - 5555:5555
