10. CNCF is an open source software foundation dedicated to making cloud native computing
universal and sustainable
CNCF was founded in December 2015 and is a part of The Linux Foundation.
CNCF curates and promotes a toolkit of trusted projects for modern applications.
Helps hosted projects to succeed in various ways, one of them is by organizing events
where the community can meet in person.

11. What projects does CNCF host?

15. Most importantly: What does
“Kubernetes” mean?
Kubernetes = Greek for “pilot” or
“helmsman of a ship”

18. Kubernetes is an open-source system for automating
deployment, scaling, and management of containerized
applications.

19. Manage Containers in production is Hard ( distributed computing is hard… )
It's become the industry standard for deploying containers in production
Supported on all clouds
Open source, backed by giants
Vibrant and fast growing community
Laying the foundation for cloud-native apps
Some reasons

23. Kubernetes - Key Concepts
Pods
Replica Sets
Services
Deployments

24. Kubernetes - Pods

25. Kubernetes - Pods
In Kubernetes, a group of one or more containers is called a Pod. Containers
in a Pod are deployed together, and are started, stopped, and replicated as a
group.

26. Kubernetes - Pods
Pod Definition
The simplest Pod definition describes the deployment of a single
container. For example, an nginx web server Pod might be defined as:

27. Kubernetes - Replica Sets

28. Kubernetes - Services

29. Kubernetes - Services and Ingress Controller

30. Kubernetes - Deployment

31. Kubernetes - Deployment
A Deployment object defines a Pod creation template (a “cookie-cutter” if you
will) and desired replica count.

32. Kubernetes - Deployment

33. Kubernetes - CI/CD Patterns
