**The full story of this presentation is now published here: http://stefana-muller.ulitzer.com/node/4098916 **Additional details: http://datagridsys.com/nomorescripts Most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes a lot of work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reduction in cost and increase in speed. In this talk, Stefana Muller will share the journey her engineering team took to continuously deploy their containerized application over the past year. Highlighting the pitfalls and lessons learned so that you too can adopt these best practices to app deployment. If you are working to adopt containers or find yourself patching together script after script to automate your deployment pipeline, this talk is for you.

1. Continuous Deployment

2. App we were trying to deploy
VCTR (pronounced Victor)
• free tool that scans containers + VMs and identifies vulnerabilities
• 5,000+ Users & Integrated with PLESK

3. to speed up application deployment,
drive down cost,
ease management and
make application delivery more flexible overall.
We used containers to make this all easy...

4. What worked well
- It was easy to package the app into containers
- It was easy to test and qa
- It was easy to create our images
Create Image ProductionBuild Deploy

5. What didn’t work well

10. Lesson 1: Scripts Have Issues

11. • Must change every time app/architecture changes
• Don’t take into account existing state of the app
• Changes are multifaceted (deploy, upgrade, tear
down)
• Don’t include error handling (debugging)
• Don’t clean up after themselves
• Prescriptive - not Descriptive (like a pipeline)
• Costly to maintain
• No one knows what’s now running
Scripts are not Features!
Lesson 1: Scripts Have Issues

12. Lesson 2: Deployment is Systematic

13. 1. Provides a descriptive model of your app
2. Easily Updates your app
3. Shares Visibility
4. Easily Makes Copies of your app
5. Continuously Deploys your app - deploy, upgrade, tear
down, roll back should be seamless
6. Integrated Troubleshooting
7. Must Integrate with Your Toolchain & Team
Requirements of a Deployment System
