Intro to Kubernetes

This guide is aimed for people who do not know what kubernetes is, but know what a container and what a virtual machine is.

We will go through the why to kubernetes, and core concepts you need to know, along with a few commands and code snippets to put things into perspective.

Quickstart

Before kubernetes was created, containers were managed within a virtual machine, and one operating system had multiple virtual machines running, each with its own operating system and multiple containers, this method works, but it’s imperative and has its own limitations when we want to handle millions of containers. Google created kubernetes exactly for this usecase.

Kubernetes is used to manage containers, it was mainly created to orchestrate how multiple containers are being handled (networking / run / down..), it does this via multiple abstraction layers, these abstractions follow a hierarchy and are designed to simplify managing containers.
