Containers have recently grown in interest in the virtualization community because they are a lightweight alternative to full machine virtualization. Containers offer an operating system level virtualization, where the kernel controls the isolation of the different containers. That means less isolation than virtual machines, but also less overhead in the system because they share parts of the kernel. The most important developments in the Open Source community are LXC and Docker. ONEDock is a set of extensions for OpenNebula to use Docker as a hypervisor in ONE, to provide containers as if they were lightweight Virtual Machines (VM). The underlying idea is that when OpenNebula is asked for a VM, a Docker container will be deployed instead. In the context of OpenNebula, it is managed as if it was a VM, and the user will be able to use IP addresses to access to the container. In this session we will learn about the integration of Docker and ONE, wich kind of the available features in ONE have been incorporated to the Docker containers, and how the operations on VMs are translated to the containers in the context of ONE. Moreover we will discuss some technical details and technical decissions taken in ONEDock, and how the other operations (that have not been implemented yet) will be integrated in ONEDock.
