How to configure a container with Apache for Drupal 8 behind another container Nginx used as a reverse proxy
Finally, I found the error.
I had to use this configuration :
<VirtualHost *:80> ServerAdmin toto@toto.com ServerName weblab.mhf.mhc DocumentRoot /srv/www/ ErrorLog ${APACHE_LOG_DIR}/client_portal.error.log CustomLog ${APACHE_LOG_DIR}/client_portal.access.log combined <Directory /srv/www/client_portal> Options -Indexes +Includes +FollowSymLinks -MultiViews AllowOverride All Require all granted </Directory></VirtualHost>For Drupal the MultiViews option has to be disable :
If the Apache server has Options +MultiViews enabled by default, then the Apache >Virtualhost configuration should also contain Options -MultiViews (or have -MultiViews >added to the existing Options directive).
