# This configuration has been tested on GitLab 8.2
# Note this config assumes unicorn is listening on default port 8080 and
# gitlab-workhorse is listening on port 8181. To allow gitlab-workhorse to
# listen on port 8181, edit or create /etc/default/gitlab and change or add the following:
#
# gitlab_workhorse_options="-listenUmask 0 -listenNetwork tcp -listenAddr 127.0.0.1:8181 -authBackend http://127.0.0.1:8080"
#
#Module dependencies
# mod_rewrite
# mod_ssl
# mod_proxy
# mod_proxy_http
# mod_headers

# This section is only needed if you want to redirect http traffic to https.
# You can live without it but clients will have to type in https:// to reach gitlab.
