如何正确配置Nginx反向代理自定义端口的GeoServer？

我在同一服务器的独立Docker容器中部署GeoServer和Spring Boot服务，通过Nginx反向代理对外提供服务。由于80、443端口不可用，选用10443作为HTTPS端口。Spring Boot服务运行正常，但GeoServer访问时出现重定向丢失端口的问题：访问https://example.com:10443/geoserver会先重定向至带端口的index.html，随后跳转至不含10443端口的https://example.com/geoserver/web/?0。

我的Nginx配置 #

location /geoserver {
  proxy_pass http://geoserver:8080/geoserver;
  proxy_set_header    Host $host;
  proxy_set_header    X-Real-IP $remote_addr;
  proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header    X-Client-Verify SUCCESS;
  proxy_set_header    X-Client-DN $ssl_client_s_dn;
  proxy_set_header    X-SSL-Subject $ssl_client_s_dn;
  proxy_set_header    X-SSL-Issuer $ssl_client_i_dn;
  proxy_redirect off;
}

docker-compose.yml配置 #

version: "3.1"
services:
  nginx:
    container_name: nginx
    image: nginx
    restart: always
    ports:
      - 10443:443
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/conf.d:/etc/nginx/conf.d
      - ./nginx/cert:/etc/nginx/cert
      - ./nginx/www:/www
      - /etc/localtime:/etc/localtime:ro
  geoserver:
    container_name: geoserver
    image: kartoza/geoserver:2.21.1
    environment:
      DB_BACKEND: POSTGRES
      HOST: postgis
      POSTGRES_PORT: 5432
      POSTGRES_DB: pgis
      POSTGRES_USER: postgis
      POSTGRES_PASS: ********
      GEOSERVER_ADMIN_USER: admin
      GEOSERVER_ADMIN_PASSWORD: ********
      GEOSERVER_DATA_DIR: /opt/geoserver/data
      GEOWEBCACHE_CACHE_DIR: /opt/geoserver/cache
      FOOTPRINTS_DATA_DIR: /opt/geoserver/footprints
      HTTP_SCHEME: https
    volumes:
      - ./geoserver/data:/opt/geoserver/data
      - ./geoserver/cache:/opt/geoserver/cache
      - ./geoserver/footprints:/opt/geoserver/footprints
      - ./geoserver/fonts:/usr/share/fonts/custom

解决方案 #

在GeoServer的环境变量中添加HTTP_PROXY_PORT: 10443即可解决重定向丢失端口的问题。
