In diesem Talk beschreibe ich die Continuous Integartion Pipeline von punkt.de und deren Entstehen. Es wird motiviert, warum es sich lohnt, eine solche Pipeline zu implementieren und welche Tools wir dafür verwendet haben. Neben der Beschreibung von Git, Jenkins, Chef, Vagrant, Behat und Surf geht es auch um Integration der einzelnen Tools in eine Deployment Kette.

TYPO3 Camp Stuttgart 2015 - Continuous Delivery with Open Source Tools
- 1. Continuous Integration & Continuous Delivery with OpenSource Tools
- 2. Annotated Version • The grey slides are additional slides added to the presentation to make it easier to understand on Slideshare etc.
- 5. Inspiration • This talk was inspired a lot by the work of my colleagues at punkt.de • And a presentation of Sebastian Helzle at FOSSASIA 2014 • http://www.slideshare.net/Sebobo/continuous- delivery-with-open-source-tools
- 6. Motivation Tests Version Control Jenkins Deployment Configuration Management Monitoring Summary & Further Reading
- 9. Motivation • We want to deliver our Software from Development to Production • In small increments
- 12. Feedback
- 13. Motivation • As a developer we want to improve constantly • Build - Measure - Learn is a Mantra for Learning • Feedback supports Learning • Continuous Integration and Delivery is a constant source of Feedback • The earlier the Feedback - the better
- 14. FTP to live Server Live Server
- 15. FTP to test Server Test Server FTP to live Server
- 16. FTP to test Server Test Server FTP to live Server
- 17. All developers work on single Dev Server instance FTP to live Server Dev Server Live Server
- 18. Version Control Build gitlab triggers Unit TestsCommit Stage build succeeds UI Tests Acceptance Stage DB Tests tests pass tests pass Deployment Stage tests pass build succeeds Build locally Demo Stage Production Stage rsync rsync git push Developer Feedback
- 19. Evolution of Software Delivery • One developer ships his software to live server using FTP • We start to use a Test Server to protect the production server • Multiple developers make the scenario more complex • Introduction of a developer server • Setup of a sophisticated deployment chain
- 20. ① Git
- 21. First Step Towards Continuous Integration if you don’t use it yet USE GIT
- 22. Gitlab Server git pull / push Developer Reviewer Merge / Decline Feature Branch Master Branch Master Feature git checkout -b feature pull !
- 23. Merge Request Workflow • No developer is allowed to directly push to master • Each developer opens a merge request for a finished feature • Any other developer can review the request and merge it into master • Provides a first feedback loop!
- 27. ② Tests
- 28. Functional Testing • Test that your code is working • Not how it is working • More black-box testing • Incorporate your Database • End-to-End testing
- 29. /** @test */ public function createCustomerCreatesExpectedCustomer() { $this->customerService->createCustomer('4711', 'MickeyMouse'); $this->persistenceManager->persistAll(); $this->assertSame( '4711', $this->customerRepository->findAll()->getFirst()->getId() ); }
- 30. Use Integration Tests • Unit tests might be the wrong tool to test, whether your application is working • Integration Tests provide a full stack test that detect defects easier
- 32. Feature: Language menu In order to switch the language on the website As a website user I need to be able to select the language in a menu Background: Given I am in "desktop" layout And I am on "/" Scenario: Switching the language from english to german When I follow "Language" And I wait for 500 milliseconds And I follow "Deutsch" Then I should be on "/de.html"
- 33. /** * Given I am in "desktop" layout * * @When I am in :layout layout */ public function iResizeTheWindowToLayout($layout) { if (array_key_exists($layout, $this->screenSizes)) { $currentLayout = $this->screenSizes[$layout]; $this->getSession()->getDriver()->resizeWindow( $currentLayout['width'], $currentLayout['height'], 'current'); return TRUE; } throw new Exception(sprintf('Layout "%s" not defined', $layout)); }
- 34. Frontend Tests with Behat • Behat Tests provide full-stack tests including the frontend • Behat uses easy-to-read language„Gherkin“ for writing tests • Selenium is used to run the tests
- 35. ③ Jenkins
- 36. Jenkins • Java Application • Can be deployed into Tomcat or Standalone • Many Plugins available • Basically a Task Runner
- 38. Deployment Stage * Demo Deployment * Production Deployment Acceptance Stage * Functional Tests * Frontend Tests Commit Stage * Clone Repository * Build Project * Unit Tests Triggered by Commit green green
- 39. Jenkins Stages • Commit Stage • Fast feedback: project builds, unit tests run? • Acceptance Stage • Slower tests: Integration tests and Frontend tests • Deployment Stage • Responsible for the Deployments to Staging and Production
- 41. TL;DR Do not „programm“ your CI / CD tasks in Jenkins - use scripts and make them part of your projects!
- 42. ④ Surf
- 43. TYPO3 Surf • A Remote Server Automation and Deployment Tool • Written in PHP • Based on the TYPO3 Flow Framework • Can be deployed as a Flow Package or Standalone
- 44. Deployment Workflow • Build Locally • Run Tests • Ship / Transfer • Run Smoketests • Only switch Release if Tests pass
- 45. Surf Concepts $workflow set up HOW to deploy $node set up WHERE to deploy $application set up WHAT to deploy $deployment glue it all together
- 46. <?php $workflow = new TYPO3SurfDomainModelSimpleWorkflow(); $node = new TYPO3SurfDomainModelNode('staging'); $node->setOptions(array( 'username' => '<username>', 'composerCommandPath' => '/usr/local/bin/composer' )); $node->setHostname($host); $application = new TYPO3SurfApplicationTYPO3Neos('<project_name>'); $application->setOptions(array( 'repositoryUrl' => '<git_remote_url>', 'keepReleases' => 5, 'packageMethod' => 'git', 'transferMethod' => 'rsync', 'updateMethod' => NULL )); $application->setDeploymentPath('<deployment_path>'); $application->addNode($node); $deployment->addApplication($application); $deployment->onInitialize(function() use ($workflow, $application, $project) { $workflow->afterStage('migrate', 'codecoon:importContent'); });

- 48. ⑤ Chef &Vagrant
- 49. Developer Machine / Laptop vagrant up Virtual Machine Workspace Project 1 chef-solo Gitlab Server git pull / push ssh mysql samba nfs samba nfs git ssh http http chef run ssh
- 50. Our Vagrant Approach * We have VirtualBox and Vagrant running on our laptop * We start a virtual machine and run Chef inside this machine * Chef sets up * Our services (Apache, PHP, MySQL, …) * Our projects / webspaces * We can now use our familiar tools to work on our projects * It feels like „working locally“ although we have a Sandbox * We cannot crash the host OS when crashing the Dev-Environment * Think about packages * Think about different software versions for different projects * Think about how long it takes to re-install your laptop…
- 51. Workspace Project 1 Workspace Project 2 Workspace Project 2 ProvisionProjects ProvisionJenkinsServer ConfigureApache ConfigurePHP &MySQL We set up our Projects on Jenkins Automatically!!!
- 52. Chef & Jenkins There shall be 2 Chef runs 1. The one that provisions our Jenkins Server [not yet finished…] 2. The one that provisions the projects inside our Jenkins Server Those Projects are „publicly“ available * We can use them as „normal“ Website (e.g. for Review and Manual Testing) * We can run UI tests on them In the future we want to change this to a master/slave approach.
- 53. ⑥ Monitoring
- 54. Monitoring Stage • Check for Website to be alive • Send Notifications • Email, Jabber, SMS • Ops: Nagios — Devs: Jenkins
- 55. Performance Stage • Check Realtime Performance of your Website • Gatling is a great Tool for writing Performance Tests • Visualize Results on Dashboard
