#Introduction At a basic level, is a system for running and coordinating containerized applications across a cluster of machines. It is a platform designed to completely manage the life cycle of containerized applications and services using methods that provide predictability, scalability, and high availability.

Kubernetes

https://github.com/kubernetes/kubernetes

And Jenkins

https://wiki.jenkins.io/display/JENKINS/Kubernetes+CLI+Plugin

https://wiki.jenkins.io/display/JENKINS/Kubernetes+Plugin A quick setup is :

get a Kubernetes cluster running
use a docker image for the agents, or create your own

Features

As a Kubernetes user, you can define how your applications should run and the ways they should be able to interact with other applications or the outside world. You can scale your services up or down, perform graceful rolling updates, and switch traffic between different versions of your applications to test features or rollback problematic deployments. Kubernetes provides interfaces and composable platform primitives that allow you to define and manage your applications with high degrees of flexibility, power, and reliability.
