How to add a subpath to root url on Apache - apache

Question

I'm using Apache 2.4 (on a Drupal 7/Docker project).
I want my all my site pages to map from /var/www/html to http://domain/foo/ (eg: /var/www/html/1/2/3/ to http://domain/foo/1/2/3/)
I prefer to avoid using .htacess and only apache conf file
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html
ServerName foo_name
# Try 1
Alias /foo /var/www/html
# Try 2
Redirect "/" "/foo/"
<Directory /var/www/html>
DirectoryIndex index.php
Options Indexes FollowSymLinks
AllowOverride All
AllowOverride None
Order Allow,Deny
Allow from All
# Try 3
RewriteEngine On
RewriteBase /foo
To do so I tried :
Alias : Alias /foo /var/www/html so I can access to my front page with http://domain/foo/ but it doesn't work on http://domain/foo/1/2/3/). And also it's just a one way redirection.
Redirect Redirect "/" "/foo/" : I did not worked on my bowser I try to acces to http://domain/foo/ but I got this url (almost infinite loop) http://domain/foo/foo/foo/foo/foo/foo/foo/foo/foo/...
RewriteBase : RewriteBase /foo but it doesn't work probably because I need to match it with htacess on subdirectory.
Most advanced rewriting : I saw a lot of them on StackOverflock/ServerFault but it did'nt seem appropriate for my problem (I never use before regex PCRE, harder to adapt). Moreover I should avoid using rewrite for that case.

It's working like that (alias + RewriteRule) :
Alias /foo /var/www/html
<Directory /var/www/html>
DirectoryIndex index.php
Options Indexes FollowSymLinks
AllowOverride All
AllowOverride None
Order Allow,Deny
Allow from All
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
