Kubernetes is an open source system for running containers across a cluster of machines.

Developed in the open by a community that spans the industry, Kubernetes has become the common foundation of the cloud native ecosystem.

Scalable

Scale to match demand. Kubernetes adjusts the number of running instances automatically based on CPU, memory, or your own metrics, and grows from a single laptop to thousands of nodes without changing how you work.

Resilient

Kubernetes keeps your applications running — restarting containers that fail, rescheduling them when a node goes down, and routing traffic only to instances that are ready. Recovery happens automatically, often before anyone notices.

Portable

Run the same way on a laptop, on-premises, or across public clouds. Kubernetes is open source with no vendor lock-in, so you can move workloads to wherever makes the most sense.

Extensible

Kubernetes is a platform to build on. Define your own resource types, automate operations with custom controllers, and draw on a vast ecosystem of tools — all through the same API, without forking the core.
