Universal update guide for patch versions

For example from 6.2.0 to 6.2.1, also see the semantic versioning specification.

0. Backup

It's useful to make a backup just in case things go south: (With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version)

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production

1. Stop server

sudo service gitlab stop

2. Get latest code for the stable branch

cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout LATEST_TAG

Replace LATEST_TAG with the latest GitLab tag you want to upgrade to, for example v6.6.3.

3. Update gitlab-shell to the corresponding version

cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v`cat /home/git/gitlab/GITLAB_SHELL_VERSION`

4. Install libs, migrations, etc.

cd /home/git/gitlab

#PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment

# MySQL
sudo -u git -H bundle install --without development test postgres --deployment

sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
sudo -u git -H bundle exec rake assets:clean RAILS_ENV=production
sudo -u git -H bundle exec rake assets:precompile RAILS_ENV=production
sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production

5. Start application

sudo service gitlab start
sudo service nginx restart

6. 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 upgrade complete!
