This might be necessary for example if you set up gitlab behind a reverse proxy. If the hostname cannot be resolved, the final installation check will fail with "Check GitLab API access: FAILED. code: 401" and pushing commits will be rejected with "[remote rejected] master -> master (hook declined)".

doc/update/7.14-to-8.0.md

+# From 7.14 to 8.0
+
+### 0. Double-check your Git version
+
+**This notice applies only to /usr/local/bin/git**
+
+If you compiled Git from source on your GitLab server then please double-check
+that you are using a version that protects against CVE-2014-9390. For six
+months after this vulnerability became known the GitLab installation guide
+still contained instructions that would install the outdated, 'vulnerable' Git
+version 2.1.2.
+
+Run the following command to get your current Git version.
+
+```
+/usr/local/bin/git --version
+```
+
+If you see 'No such file or directory' then you did not install Git according
+to the outdated instructions from the GitLab installation guide and you can go
+to the next step 'Stop server' below.
+
+If you see a version string then it should be v1.8.5.6, v1.9.5, v2.0.5, v2.1.4,
+v2.2.1 or newer. You can use the [instructions in the GitLab source
+installation
+guide](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/installation.md#1-packages-dependencies)
+to install a newer version of Git.
+
+### 1. Stop server
+
+    sudo service gitlab stop
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Get latest code
+
+```bash
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+```
+
+For GitLab Community Edition:
+
+```bash
+sudo -u git -H git checkout 8-0-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+sudo -u git -H git checkout 8-0-stable-ee
+```
+
+### 4. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+sudo -u git -H git fetch
+sudo -u git -H git checkout v2.6.4
+```
+
+### 5. Install gitlab-git-http-server
+
+First we download Go 1.5 and install it into /usr/local/go.
+
+    curl -O --progress https://storage.googleapis.com/golang/go1.5.linux-amd64.tar.gz
+    echo '5817fa4b2252afdb02e11e8b9dc1d9173ef3bd5a  go1.5.linux-amd64.tar.gz' | shasum -c - && \
+      sudo tar -C /usr/local -xzf go1.5.linux-amd64.tar.gz
+    sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
+    rm go1.5.linux-amd64.tar.gz
+
+Now we download gitlab-git-http-server and install it in /home/git/gitlab-git-http-server.
+
+    cd /home/git
+    sudo -u git -H git clone https://gitlab.com/gitlab-org/gitlab-git-http-server.git
+    cd gitlab-git-http-server
+    sudo -u git -H make
+
+If you put your Git repositories in a directory different from /home/git/repositories, you need to tell gitlab-git-http-server about it via /etc/gitlab/default.
+See lib/support/init.d/gitlab.default.example for the options.
+
+### 6. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without ... postgres')
+sudo -u git -H bundle install --without development test postgres --deployment
+
+# PostgreSQL installations (note: the line below states '--without ... mysql')
+sudo -u git -H bundle install --without development test mysql --deployment
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Clean up assets and cache
+sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
+
+# Update init.d script
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+### 7. Update config files
+
+#### New configuration options for `gitlab.yml`
+
+There are new configuration options available for [`gitlab.yml`](config/gitlab.yml.example). View them with the command below and apply them to your current `gitlab.yml`.
+
+```
+git diff origin/7-14-stable:config/gitlab.yml.example origin/8-0-stable:config/gitlab.yml.example
+``````
+
+#### New NGINX configuration
+
+Because of the new gitlab-git-http-server you need to update your NGINX configuration.
+If you skip this step 'git clone' and 'git push' over HTTP(S) will stop working.
+
+```
+# Remove '-ssl' twice in the diff command below if you use HTTP instead of HTTPS
+git diff origin/7-14-stable:lib/support/nginx/gitlab-ssl origin/8-0-stable:lib/support/nginx/gitlab-ssl
+```
+
+### 8. Start application
+
+    sudo service gitlab start
+    sudo service nginx restart
+
+### 9. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+
+To make sure you didn't miss anything run a more thorough check with:
+
+    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (7.14)
+
+### 1. Revert the code to the previous version
+Follow the [upgrade guide from 7.13 to 7.14](7.13-to-7.14.md), except for the database migration
+(The backup is already migrated to the previous version)
+
+### 2. Restore from the backup:
+
+```bash
+cd /home/git/gitlab
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+If you have more than one backup *.tar file(s) please add `BACKUP=timestamp_of_backup` to the command above.
