Apache в качестве обратного прокси-сервера для Docker-контейнера

Я пытаюсь настроить Apache 2.4 в качестве обратного прокси-сервера для моего контейнера docker nextcloud:fpm. У меня есть рабочий конфиг nginx, но я хочу, чтобы контейнер использовал kerberos sso, и для этого нет модуля nginx Debian10.

Здесь, на GitHub, есть пример конфигурации nginx.

Это мой рабочий конфиг nginx:

upstream php-handler {
    server 127.0.0.1:9900;
}


server {
    listen 80 http2; 
    listen [::]:80 http2;

    server_name cloud-test.zege.at;
    root /home/storage/nextcloud;

Особенно в fastcgi то, что я не понимаю в Apache.

Заранее спасибо за подсказки.
