GitLab and ISPConfig 3 issue - apache

Question

I have a website managed with ISPConfig 3 on a VPS running Debian 8 and Apache.
The website is accessible via domain.ee but I want to get my GitLab running (on the same time) on git.domain.ee
But when I installed GitLab and runned it, he overwrited ISPConfig and started to run on git.domain.ee AND domain.ee (and all the others adresses pointing to my VPS)
Here is my gitlab.rb config:
external_url 'http://git.domain.ee'
unicorn['port'] = 8080
web_server['external_users'] = ['www-data']
And here is my gitlab.conf runned by apache:
<VirtualHost *:80>
ServerName git.domain.ee
ServerSignature Off
ProxyPreserveHost On
<Location />
Order deny,allow
Allow from all
ProxyPassReverse http://127.0.0.1:8080
ProxyPassReverse http://git.domain.ee/
</Location>
RewriteEngine on
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule .* http://127.0.0.1:8080%{REQUEST_URI} [P,QSA]
DocumentRoot /opt/gitlab/embedded/service/gitlab-rails/public
</VirtualHost>
Obviously domain.ee is replaced with my real domain name.

Answer 1

let git run on localhost:8080 and configure apache as reverse proxy
like so:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ProxyVia Off
<Proxy *>
Require all granted
</Proxy>
ProxyPass / http://127.0.0.1:8080
ProxyPassReverse / http://127.0.0.1:8080
</VirtualHost>
you can add the other rules as you need them
