Automated Drupal deployment with Git and Capistrano
The document discusses the use of Git and Capistrano for automating Drupal deployments, emphasizing the reduction of manual errors and streamlining the deployment process. It outlines the steps involved in deploying with Capistrano, including commands like 'cap deploy' and 'cap deploy:rollback', as well as the directory structure created on the server. Additionally, it covers the importance of using tools like Drush and provides references for further learning on the topic.
Automated Drupal deployment with Git and Capistrano
- 1. Automated Drupal deployment with Git& Capistrano Farez Rahman Freelance Drupal developer Co-founder: OnSavvy.com
- 2. About this session Git+Capistranofor deployment Mainly Capistrano Overview - not too detailed Input/feedback/questions from you guys Lots of info online - links at the end
- 3. Show of handsplease... Some sort of automated deployment process Git and Capistrano Git only + SSH FTP/SFTP Aegir? Drush? Pantheon? No idea!
- 4. Goal Automated deployment: reduce manualhuman error Anyone can deploy: startup = speed is important
- 5. Wins... Reduced multiple stepsturned into one step ssh, git pull, update db, revert features, clear cache... “cap deploy”
- 6. Wins... Less steps missedout due to human error
- 7. Wins... No manual SSHinto server great for non-geeks
- 8. Wins... Doing more foreach deploy just add to deploy script
- 9. Wins... Quick to rollback “capdeploy:rollback”
- 10.
- 11. Costs... Setup costs... capistrano, ruby trainingfor other team members
- 12. Costs Security potential to runmalicious commands on server from developer’s machine
- 13. Why capistrano Looked ata few options (git hooks, Jenkins, capistrano) capistrano - simple, does the job for us Drupal deploy scripts available (capdrupal, capistrano-drupal)
- 14. Capistrano Ruby Gem Remote controlfor server commands No server-side installations Runs over SSH
- 15.
- 16. CapDrupal (Ruby Gem) Drupal-specificCapistrano tasks We use modified version of CapDrupal There are others (cap-drupal, capistrano- drupal...)
- 17.
- 18. Drush CapDrupal needs Drushon your server Capistrano itself doesn’t.. but no Drush = limited options
- 19. How to deploy 1.Make local changes 2. git commit and push 3. $ “cap deploy” That’s it
- 20. What “cap deploy”does SSH into server Takes site offline Backup of db (using drush & backup_migrate) Clones latest revision from dev branch Points site root to that latest clone Runs update db Reverts features Clears cache Puts site back online
- 21. Directory structure onserver current -> releases/20130805211651 (symlink) releases/ 20130801135258 20130805211547 20130805211651 shared/ cached-copy/ files/ settings.php NB: running “cap deploy:setup” creates the dir structure
- 22. Before “cap deploy” current-> releases/20130805211651 releases/ 20130801135258 20130805211547 20130805211651 shared/ cached-copy/ files/ settings.php
- 23. After “cap deploy” current-> releases/20130805212640 (points to new clone) releases/ 20130801135258 20130805211547 20130805211651 20130805212640 <- new git clone shared/ cached-copy/ files/ settings.php
- 24. Local directory structure app/<- drupal root config/ deploy.rb <- project specific settings dev.rb <- site specific settings live.rb Capfile
- 25.
- 26. Local directory structure app/<- drupal root config/ deploy.rb <- project specific settings dev.rb <- site specific settings live.rb Capfile
- 27.
- 28. Rolling back “cap deploy:rollback” Doesn'trollback database But can create custom cap tasks to do that
- 29. Customisations to Capdrupal “backupdb”, “update db”, “revert features” = not relevant when only updating CSS so we removed them from deploy task can be run by themselves when needed
- 30. All Capistrano tasks“cap -T”
- 31. Potential improvements Create backupsof db, that can be rolled back (e.g new copy of db and settings.php for each new deploy) Fully automated deployment, continuous integration
