Kubernetes

Kubernetes, also known as K8s, is an open-source system for automating the deployment, scaling, and management of containerized applications. By grouping containers that make up an application into logical units, Kubernetes aims to simplify management and discovery. Kubernetes supports a range of container tools, including Docker. Originally designed by Google and donated to the Cloud Native Computing Foundation (CNCF), Kubernetes builds on fifteen years of experience running production workloads. Kubernetes is open source and allows users to utilize on-premises, hybrid, or public cloud infrastructure.
