PuppetConf 2016: Using Puppet with Kubernetes and OpenShift – Diane Mueller, Red Hat & Daniel Dreier, Puppet
- 1. Using Puppet With Kubernetes and OpenShift Diane Mueller, Red Hat Daniel Dreier, Puppet
- 2. Our Agenda Today ● OpenShift is Enterprise-Ready Kubernetes for Developers ● Puppet provides a common configuration modeling layer across container platforms and traditional infrastructure ● Both shift focus from infrastructure to applications 2Preso title goes here.

- 3. Infrastructure is distracting Applications are the important part 3
- 4. Infrastructure is distracting ● Same basic patterns endlessly re-implemented ● Too much friction for developers ● Impedance mismatch of declarative languages and underlying OS ● Humans make decisions that computers should 4Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All
- 6. Business Impact 1. Our time goes into low-value integration work 2. Hardware is under-utilized 3. Useful tools don’t get deployed 4. Infrastructure is unnecessarily fragile 6Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All
- 8. CIO perspective “The main point here is that OpenShift, with its support for Docker and Kubernetes, is helping clients with their container deployments, which CIOs view as a more important strategic decision than what underlies those workloads.” Barclays PLC Analyst Source: Barclays Research Report Preso title goes here.

- 9. OpenShift is Kubernetes OpenShift provides common developer-centric workflows across all applications 9Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All =
- 10. What Is OpenShift? ● Use containers for efficiency ● Hide details of underlying infrastructure with app specific abstractions ● Portable across different clouds or bare metal ● Package my application and all of its dependencies ● Deploy to any environment in seconds and enable CI/CD ● Config driven approach - possible to define application in bulk INFRASTRUCTURE APPLICATIONS Application-centric Platform
- 11. Why OpenShift? Provide a secure multi-tenant distribution of Kubernetes Optimized for team software development and deployment Able to create and deploy applications in seconds And run and support all of the stateful parts of an application Easily. How is it different from Kubernetes?
- 12. OpenShift Goals Make Kubernetes the best place to run all applications Provide well integrated tools to empower developers Ensure that applications can be portable to any environment Put extra resources to use for developers What is the mission of OpenShift Origin
- 13. 10,000 foot overview from kernel to the app
- 14. OpenShift runs on your choice of infrastructure
- 15. Nodes are instances of RHEL where apps will run
- 16. Apps and components run in containers Container Image Container Pod
- 18. Pods are the orchestrated unit in OpenShift
- 19. What about app data?
- 20. Routing layer for external accessibility
- 21. Access via Web UI, CLI, IDE, API
- 23. Declarative Set a target temperature and the thermostat turns the furnace on and off Imperative The furnace turns on and off on command Modeled Software logic changes desired temperature based on many factors 23Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All Furnace Abstraction Layers
- 24. Declarative Types and providers assert and enforce a desired state Imperative Commands run by Puppet types and providers Modeled Puppet code determines the desired state 24Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All Abstractions for managing servers
- 25. Declarative Two nginx pods should be running right now Imperative Run nginx right now Modeled Puppet code specifies two nginx pods in staging, and four in production 25Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All
- 26. Common Modeling Layer What Puppet Can Model ● Underlying OS ● Container contents ● Kubernetes and OpenShift resources ● Interactions with existing infrastructure 26Preso title goes here. To update, go to File > Page Setup > Header/Footer, paste title, Apply All

- 30. Enterprise Customers of OpenShift
- 31. Business Challenges ● Need to match traveler’s reservation requests to various providers’ inventory (airlines, hotels, etc.) ● Dealing with constant updates from provider systems all over the world ● Must deliver high consistency and fast response times ● Managing very high request volumes of up to ~210,000 queries per second at peak ● Application-centric deployments, deploying the application as a whole with all of its dependencies. ● Automated scheduling across the cluster, decoupling ‘what should run’ from ‘where it should run’ ● Able to support different types of applications, not limited to HTTP or stateless services ● Improved operational model and greater efficiency Key Benefits Production Workloads @ Scale
- 32. Business Value 1. 8 months pay back on the initial investment 2. ~530% ROI over 5 years 3. 66% faster app delivery and deployment 4. 35% reduction in AppDev staff time 5. 20% improvement in IT staff productivity 6. 40% reduction in infrastructure costs 32Preso title goes here.
