3 likes647 views
The document discusses continuous delivery (CD) as a mindset focused on automating build, testing, and deployment to enhance software quality and speed to market. It outlines the prerequisites for implementing CD in PHP projects, including the need for automated testing and process authority, while providing insights into using Bamboo and Rocketeer for deployment automation. The author stresses the importance of starting with basic CD principles before exploring advanced techniques like feature toggles and canary releases.

High Stakes Continuous Delivery in the Real World #OpenWest
- 1. High Stakes Continuous Delivery in the Real World Presented by Joshua Warren
- 2. OR:
- 3. How I Learned To Stop Worrying and Love Deployments
- 5. About Me
- 6. PHP Developer Working with PHP since 1999
- 7. Founder & CEO Founded Creatuity in 2008 PHP Development Firm Focused on the Magento platform Some of our developers, October ‘12
- 8. Frequent Conference Presenter Occasional Open Source Contributor Over-Tweeter
- 10. IMPORTANT! • joind.in/13900 • Download slides • Post comments • Leave a rating!
- 12. –ContinuousDelivery.com “Releasing high quality software fast through build, test and deployment automation.”
- 13. Testing + Automation Increases confidence in completed code Decreases delay between task completion & deployment
- 14. #OpenWest Continuous delivery is a mindset, not a technology.
- 15. Any code you commit may be released to customers at any point.
- 17. Yes, any code you commit may be released to customers at any point.
- 18. Commits made by Google’s Customer Surveys team are live in production in just 8 minutes.
- 19. Or: The Benefits of Continuous Delivery WHY WOULD YOU DO THAT?!
- 20. Frequent feedback from end-users
- 21. Business advantages - reduce time to market, react to changes faster
- 22. Efficient Developers focus on developing, not deploying
- 23. Or: How to Implement Continuous Delivery for PHP Projects OK, YOU’VE CONVINCED US…
- 24. Prerequisites • Automated testing • Authority to change processes
- 25. #OpenWest Make your workflow and process changes before beginning to implement a continuous delivery system.
- 26. Change Your Workflow Today
- 27. Our Workflow at Creatuity
- 28. Each branch should be a self-contained new feature
- 29. When work is complete on a branch, that branch must be completely ready to deploy
- 30. Completed branch is tested by our continuous integration server
- 31. Completed branch is tested by our QA team
- 32. Branch is indicated as deploy-ready
- 33. Branch is deployed to production
- 34. CI Server • Bamboo, Jenkins or ? - choice is yours • Our examples will use Bamboo
- 35. Bamboo Testing • Configure it to your liking • We use phing, phpunit, etc • Must define an artifact, but can be empty
- 36. Bamboo Deployments • Create a deployment project • Define an environment - in our case, ‘Staging’ • Attach it to your build plan used for testing
- 38. Bamboo Environments • Environments are just labels • Environment-specific details will be stored elsewhere
- 40. Bamboo Tasks • Tasks are where the magic happens • We use tasks to trigger our deployment system, rocketeer
- 42. For now, it’s a magic box… What’s Rocketeer?
- 44. But we’ll learn more in a bit… Yup, a magic box
- 45. Rocketeer Check Task rocketeer check --on-staging -n
- 46. Rocketeer Deploy Task rocketeer deploy —on-staging -n
- 47. #OpenWest Four short tasks in Bamboo are all it takes to automate deploying your PHP projects.
- 48. Bamboo Triggers Deploys are triggered on schedule or after every passing build
- 49. Bamboo Notifications We trigger HipChat notification on every deploy start & finish
- 50. Each Successful Build Results in an Automatic Deployment
- 51. Deployments are reported to HipChat, appear on the deployment board in Bamboo
- 53. JIRA Integration Include JIRA issue keys in your commit message
- 54. #OpenWest Bamboo + Rocketeer takes us from passed test to deployment in less than half an hour with no manual steps.
- 55. The magic behind our automatic deployments ROCKETEER
- 58. Rocketeer is a modern PHP task runner and deployment package.
- 59. Install Rocketeer wget http://rocketeer.autopergamene.eu/versions/rocketeer.phar chmod +x rocketeer.phar mv rocketeer.phar /usr/local/bin/rocketeer
- 60. Configure Rocketeer cd <checked out copy of your codebase> rocketeer ignite
- 61. Rocketeer adds a .rocketeer folder to your project Commit this folder
- 62. Committing .rocketeer allows Bamboo plus anyone on your team to run deployments
- 63. ‘rocketeer ignite’ will configure most of it’s files for you
- 64. We’ll modify a few of the files for project-specific details
- 65. Don’t worry…
- 66. .rocketeer/config.php Edit host record if you’re using a non-standard SSH port
- 67. .rocketeer/hooks.php • Add project-specific commands • We’ll add a few Magento-specific items
- 68. .rocketeer/hooks.php 'before' => [ 'setup' => [], 'deploy' => array( 'magerun sys:maintenance --on' ), 'cleanup' => [], ],
- 69. .rocketeer/hooks.php 'after' => [ 'setup' => [], 'deploy' => [], 'cleanup' => array( 'magerun sys:setup:run', 'magerun cache:clean', 'magerun cache:flush', 'magerun index:reindex:all', 'magerun sys:maintenance --off', ), ],
- 71. .rocketeer/strategies.php return $composer->install([], ['--no-interaction' => null, ’--no-dev' => null, '--prefer-dist' => null, '--no-plugins' => null]);
- 72. Next Up • Commit these changes to your Rocketeer files • Prepare your server to receive the deployment
- 73. Server File Structure • current • releases • shared
- 74. File Structure • current and releases are managed by Rocketeer • shared contains folders shared by each release
- 75. Magento Shared Files • app/etc/local.xml • media • var
- 76. Rocketeer Folder Structure • Rocketeer deploys to a new folder under releases • Updates symlinks to shared folder • Then updates current symlink to new release
- 77. Rocketeer Prep • Make sure SSH keys are setup correctly • Rocketeer will connect to your SSH repo via your server - before running deploy for the first time, test your SSH setup
- 78. SSH config file Host yourGitServer.example HostName yourGitServer.example IdentityFile ~/.ssh/your_public_key_rsa IdentitiesOnly yes
- 79. Rocketeer Prep • rocketeer check • rocketeer deploy —pretend • That’s it - you’re ready to deploy!
- 81. Or: What’s Next? WHERE DO WE GO FROM HERE?
- 82. Advanced Rocketeering • Custom tasks • Listening to events, firing events • Task builder • Task queues
- 83. Feature Toggles • First step of implementing a new feature - wrap it in a feature toggle • Code only executes if feature is enabled • Enables deploying new code immediately
- 84. Canaries • Deploy to a small portion of your site’s traffic • Compare error rates between new & old version • If error rate is same or lower, deploy globally
- 85. Don’t get distracted by these advanced concepts - start by moving to basic continuous delivery first.
