- 11. Optimize assets
- 12. Optimize assets Enter Grunt → http://gruntjs.com
- 13. Optimize assets Combine and minify javascript
- 14. Optimize assets Combine and minify javascript You can use grunt-contrib-uglify
- 15. Optimize assets Preprocess, combine and minify styles
- 16. Optimize assets Preprocess, combine and minify styles You can use grunt-contrib-sass & grunt-contrib-cssmin
- 17. Optimize assets Optimize and combine images
- 18. Optimize assets Optimize and combine images You can use grunt-spritesmith & grunt-contrib-imagemin
- 19. Optimize assets Optimize and combine font files (SVG only)
- 20. Optimize assets Optimize and combine font files (SVG only) You can use the same grunt-contrib-imagemin
- 22. Enter Capistrano → http://capistranorb.com
- 23. “A remote server automation and deployment tool written in Ruby.” “Capistrano is written in Ruby, but it can easily be used to deploy any language.”
- 24. Run “cap install” on your project folder
- 25. Capfile defines requirements for your deployment tasks→ config/deploy.rb shared configuration for all the stages→ config/deploy/*.rb defines multiple stage deployment→ lib/capistrano/tasks where your custom tasks are defined→
- 26. Lots of tasks off-the-shelf that integrate with the Ruby on Rails framework bundler, assets, migrations, Passenger, etc... You just need to include the gems in your Gemfile and uncomment the require in the Capfile
- 27. Sample Capfile
- 30. Different roles available: app, web, db Also, you can define several servers at once, eg:
- 31. Available tasks
- 32. Deployment Run 'cap <stage> deploy' on your console
- 33. Deployment flow
- 34. Rollback Run 'cap <stage> deploy:rollback' on your console
- 35. Rollback flow
- 36. You can attach to any step to run custom commands using 'before' and 'after' from Capistrano DSL, eg:
- 37. Not a Rails shop? You might need manual work creating your recipes, although there is some hope in certain cases: capistrano-node-deploy Node.js apps→ capistrano-virtualenv virtualenv python apps→ capistrano-django Django apps→ capistrano-go Go apps→ Caveat emptor! Might be old, untested or unsuitable
- 38. Where to go from here? Infrastructure management tools like Chef or Puppet for server provisioning Continuous integration hooks for automated deployment to staging servers
- 39. Talk deployed Questions? Damián Serrano Thode @dsthode MalagaMakers GeekBeers (20150115)
