What is kubernetes?

Kubernetes (also called K8s) is an open-source tool that helps you run and manage applications across many computers. If you have an app that needs to spread across multiple servers to handle heavy traffic or stay online even if one machine crashes, this project automates the deployment, maintenance, and scaling of that app. At a high level, it takes application code that has been packaged into standalone units, often called "containers", and figures out which servers should run them. It keeps watch over everything. If your app suddenly gets a spike in visitors, it can automatically spin up more copies to handle the load. If a server fails, it moves the affected app pieces to a healthy machine. The project draws on years of Google's internal experience running massive computer systems, combined with community best practices. A startup founder launching a new app, a product manager overseeing a busy e-commerce platform, or a growing company moving its services online would all use this to keep their software running smoothly without manually babysitting individual servers. It is designed for teams that need their apps to be reliably available around the clock and capable of growing alongside their user base. The project maintains a public list of real-world case studies showing how various organizations deploy it. For those who want to contribute or build the software from scratch, the project is written in the Go programming language. The README notes you can build it if you have either a Go or a Docker environment set up. The project is open source, maintained under the Cloud Native Computing Foundation, and operates with a formal community governance structure, including public meetings and a steering committee.
