In a nutshell, Kubernetes services are an abstraction for pods, providing a stable, virtual IP (VIP) address. As pods may come and go, for example in the process of a rolling upgrade, services allow clients to reliably connect to the containers running in the pods, using the VIP. The virtual in VIP means it’s not an actual IP address connected to a network interface but its purpose is purely to forward traffic to one or more pods. Keeping the mapping between the VIP and the pods up-to-date is the job of kub
CoreOS + Kubernetes on Vagrant (Single Machine) #GWO2016
While Kubernetes is designed to run across large clusters, it can be useful to have Kubernetes available on a single machine. This guide walks a deployer through this process using Vagrant and CoreOS. After completing this guide, a deployer will be able to interact with the Kubernetes API from their workstation using the kubectl CLI tool.
