nginx 不會在 docker 80 以外的端口上偵聽 pgadmin

Question

我的服務器上有幾個項目正在運行，我無法使用端口 80。在這個 Docker 中，除了 Pgadmin 之外，一切正常。 無論我如何更改代碼，我都會在 <SERVER_IP>:8090/pgadmin/ 中收到 502 錯誤或 404 錯誤

任何人都可以指導我嗎？

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;
    }
}

和 pgadmin 環境：

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

Answer 1

因為PGADMIN_LISTEN_PORT=5555正在監聽端口5555

所以gis_pgadmin容器應該監聽那個端口5555

Nginx 會從8090轉發 --> 5555

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