Continuous integration, delivery and deployment may have slightly different meanings, but the underlying goal is to deploy frequent, smaller iterations of the application. However, according to Forrester Research, less than one-third of respondents reported that their development team uses continuous integration processes on a daily basis.

While it can be a struggle to achieve continuous delivery due to corporate culture or general workflow issues between Dev and IT Operations, there are some specific tools available to help make it a reality. With continuous delivery organizations gain a competitive edge since they can make changes to their application faster and better meet the needs of their end users.

Join Ho Ming Li, Cloud Engineer and John Wetherill, Developer Evangelist for a live 45 minute presentation on continuous delivery using Jenkins, an open-source continuous integration server, and Stackato, a private PaaS by ActiveState.

In this webinar we will discuss and demonstrate:
- What is continuous integration, delivery and deployment?
- Why is it necessary?
- What are some continuous integration tools available?
- How to use Jenkins for scheduled deployments
- How Jenkins and Stackato can work together

  • 1. Continuous Delivery with Jenkins & Stackato Ho Ming Li John Wetherill Nov 2013
  • 2. Recent Events DevOps Days x 2
  • 3. Today’s Speakers Ho Ming LiCloud Engineer John WetherillDeveloper Evangelist
  • 4. What is Continuous Delivery? • • • Continuous integration: your application always builds and passes its tests, including all the pieces from different sub-teams. Continuous delivery: your application always builds and deploys to a test environment and passes its tests. Continuous deployment: your application is always ready to deploy to production through a largely automated process. source:
  • 5. Why CI / CD? Automate and Streamline Everything! Increase Operational Efficiency! Avoids: 1. wait time 2. handoff conflicts 3. human errors
  • 6. Why CI / CD? Know results earlier! Fix bugs faster! More stable builds!
  • 7. Tools Good ol’ shell scripts with cron! Extends to other languages and unix utilities Additional Features: Tracking, Dashboard
  • 8. Continuous Delivery and Stackato More, Better, Faster
  • 9. Stackato Private PaaS A private PaaS enables enterprise developers to leverage all the benefits of a public PaaS to easily deploy, manage, monitor, and scale applications, while meeting the security and privacy requirements your enterprise demands. Based on Cloud Foundry Your own Heroku Your own Google App Engine
  • 10. More Options Languages/Frameworks DB/MSG Services Local/Private/Public
  • 11. Deploy More Any time you want. Any frequency you want. Weekly? Daily? Hourly? On Commit? on Pull Request?
  • 12. Better Consistent workflow : work one, work all Self-service : Better relationship between Dev and Ops
  • 13. Faster Automation / No re-configuration Use containers and not VMs Overall a Faster Time to Market
  • 14. Containerization • resource and process isolation • namespaces: * pid * mnt * net * uts * ipc * user • compare with Solaris zones, freebsd jails
  • 15. Containerization Features for CD Multitenancy • dev, qa, prod on same cloud • no resource contention Lightweight • very fast startup (100ms) and teardown • small memory and disk footprint (COW) Snapshots / Backups • bit-for-bit copy of tested image goes to prod • bit-for-bit copy of crashed image for analysis
  • 16. Containerization Features for CD uts namespace • each container has its hostname • helpful for updates and rollbacks net namespace • multiple virtual interfaces per container • firewall rules and iptables • interface pairs for outside communication • enables multiple services on “same port” ex: multiple tomcats on 8080 user namespace • unprivileged user on host can be root in container
  • 17. Design for CI and for Cloud • can leverage dns for version-swapping • statelessness is key • simplifies updates and rollbacks • REST
  • 19. Thank you! #Stackato on Freenode Ho Ming Li John Wetherill Nov 2013
