Introduction
What is Kubernetes?
Kubernetes (K8s) is an open source orchestration system developed by Google to automate the deployment, scaling and management of container-based applications. The project is now maintained by the Cloud Native Computing Foundation (CNCF).
What is Kubernetes used for?
Kubernetes essentially provides a set of tools and processes that alleviate the operational burden associated with deploying, running, scaling, and managing container-based applications. This allows you to focus on writing code instead of managing infrastructure.
Kubernetes vs Docker
Docker is a container runtime. You can think of containers as lightweight, self-contained executable packages that include everything you need to run your application such as code, libraries, and dependencies. Kubernetes was designed to make deploying and managing (aka, orchestrating), multiple containers from multiple container runtimes easier.
Note that Kubernetes supports many different contain runtimes including containerd, CRI-O, and any other implementation of the Kubernetes CRI (Container Runtime Interface).
