It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon a decade and a half of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.
Designed on the same principles that allows Google to run billions of containers a week, Kubernetes can scale without increasing your ops team. From testing locally to running a global enterprise, your application scales consistently and easily.
Simple cases, complex cases. Kubernetes is flexible enough for your needs.
Kubernetes is open source giving you the flexibility to take advantage of on-premise, hybrid, or public cloud infrastructure allowing you to easily move workloads to where it matters to you.
Brendan Burns, Software Engineer and a founder of Kubernetes at Google, gives a technical overview of Kubernetes in this 30-minute presentation from CoreOS Fest 2015.
Automatically places containers based on their resource requirements and other constraints, never sacrificing availability. Mix critical and best-effort workloads in order to drive up utilization and save even more resources.
Restarts containers that fail, replaces and reschedules containers when nodes die, kills containers that don't respond to your user-defined health check, and doesn't advertise containers to clients until they are ready to serve.
Scale your application up and down with a simple command, a UI, or automatically based on CPU usage.
No need to modify your application to use an unfamiliar service discovery mechanism. Kubernetes gives containers their own IP addresses and a single DNS name for a set of containers, and can load-balance across them.
Kubernetes progressively rolls out application and configuration changes, while monitoring application health to ensure it doesn't kill all your instances at the same time. If something goes wrong, Kubernetes will rollback the change for you. Take advantage of a growing ecosystem of deployment solutions.
Deploy and update secrets and application configuration changes without rebuilding your image and without exposing secrets in your stack configuration.
Automatically mount the storage system of your choice, whether from local storage, a public cloud provider such as Google or Amazon, or a network storage system such as NFS, iSCSI, Gluster, Ceph, Cinder, or Flocker.
In addition to services, Kubernetes can manage your batch and CI workloads, replacing containers that fail, if desired.
