I have published a new article on InfoQ, Scaling Docker with Kubernetes, where I describe the Kubernetes project and how it allows to run Docker containers across multiple hosts.
Kubernetes is an open source project to manage a cluster of Linux containers as a single system, managing and running Docker containers across multiple hosts, offering co-location of containers, service discovery and replication control.
Included in the article there is an example of scaling Jenkins in a master – multiple slaves architecture, where the slaves are running in Kubernetes. When I finally find the time I will implement a Jenkins Kubernetes plugin that would handle the scaling automatically.
