Using CI for continuous delivery Part 1

  1. 1. Using CI tools for continuous delivery? Can we use CI tools for Continuous Delivery? www.vishalbiyani.com/cicontinuous-delivery www.vishalbiyani.com
  2. 2. What will we do? • Test drive each of – Go (ThoughtWorks) – TeamCity (Jetbrains) – Bamboo (Atlassian) – Jenkins (Open Source) www.vishalbiyani.com
  3. 3. On what basis? Parameter Description Support for CI+CD Semantics Ability to club information from multiple builds into a release manifest sorts First-class Workflow support Visual workflow - to build workflow which is easy to see and modify over time Standard actions available Standard actions available for various CD tasks - like deploy to tomcat, connect to server X etc. Custom actions- extensibility Ability to write custom actions/plugins for doing ad-hoc jobs, because not all actions provided in tool might fit your needs. Miscellaneous factors Supports rolling deployments? Agentless or with Agents? Horizontally Scalable? Auto roll back? Database deployment integration? www.vishalbiyani.com
  4. 4. Rough workflow we will test A code commit invokes a build Start Tomcat if not up Invoke test script Build, unit test, create package Deploy application Wait on response from script Restart Tomcat Indicate success/failure www.vishalbiyani.com
  5. 5. Go - ThoughtWorks http://www.thoughtworks.co m/products/go-continuousdelivery www.vishalbiyani.com
  6. 6. Notice: What we are doing now is in “Admin”- creation part. Pipelines tab is for running what we build here We create a pipeline with three “stages” and configure it www.vishalbiyani.com
  7. 7. You can integrate with project tracking tools like Mingle or others! Material for a build pipeline will be source code from any of repositories www.vishalbiyani.com
  8. 8. The “stages” in plan and number of “jobs” in each stage www.vishalbiyani.com
  9. 9. Environment variables can be configured at multiple levels. “Secure” ones only at pipeline level www.vishalbiyani.com
  10. 10. Diving one level deeper – A job can have settings, tasks, artifacts and env. Variables defined www.vishalbiyani.com
  11. 11. The tasks available look like few, but with “Custom Command” you can literally integrate anything from a shell script to external program Moreover the “command repository” provides additional commands so you don’t have to start from scratch! You can build your private command repo from existing scripts too! www.vishalbiyani.com Check https://github.com/goteam/go-command-repo
  12. 12. Let’s add a “maven” custom command to build our checked out source code Similarly we added custom commands for tasks in other stages – to build a pipeline www.vishalbiyani.com
  13. 13. Other options while creating pipelines including templates, authentication and repos etc. www.vishalbiyani.com
  14. 14. The only plugin which was available in OOTB installation Configure “Agents” which will execute tasks www.vishalbiyani.com
  15. 15. All our pipelines and their stages visible in pipelines tab. www.vishalbiyani.com
  16. 16. For a given pipeline – all past builds with stage level results in a single page. www.vishalbiyani.com
  17. 17. You can see where the material is going and what is being built ;) www.vishalbiyani.com
  18. 18. Overall progress, with rest of details like materials, jobs and comparison of changes A history of given stage in previous runs! www.vishalbiyani.com
  19. 19. We loved the visual workflow and overall information we got while running pipeline www.vishalbiyani.com
  20. 20. Successful builds and trends over time www.vishalbiyani.com
  21. 21. Comparison of Build 12 and 13 for a pipeline – stage wise and changes committed as part of change www.vishalbiyani.com
  22. 22. Go - Concluding thoughts • Clean, minimal interface • Pretty good at both CI-CD Semantics • Looks basic OOTB but Highly extensible and can be customized to needs with command repo (Kind of actions etc.) • Very well done visual workflows and information required for deploys www.vishalbiyani.com
