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.

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

Kubernetes - Key Concepts Pods Replica Sets Services Deployments
Kubernetes - Pods
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.
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:
Kubernetes - Replica Sets
Kubernetes - Services
Kubernetes - Services and Ingress Controller
Kubernetes - Deployment
Kubernetes - Deployment A Deployment object defines a Pod creation template (a “cookie-cutter” if you will) and desired replica count.
Kubernetes - Deployment
Kubernetes - CI/CD Patterns
