Getting Started with Containers and Kubernetes

This Kubernetes tutorial explains how to harness Kubernetes Meetup Kit technologies and deploy the “Hello World” Flask app onto a DigitalOcean Kubernetes cluster. Getting Started with Containers and Kubernetes. Getting Started with Kubernetes Meetup Kit. Containers offer the same process isolation, but are generally more lightweight, portable, and performant than full virtualization. Container clusters, which can be used to manage thousands of running containers across a set of physical machines, abstract away much of the work of rolling out new versions of applications, scaling them, and efficiently scheduling workloads. Out of these, Kubernetes has emerged as a mature, production-ready system.
