Operating system level virtualization is a technology that has recently emerged into the cloud services paradigm. It has the advantage of providing better performance and scalability than para-virtualized or full virtualization hypervisors. This solution is getting acceptance into cloud infrastructures. Nowadays public cloud Infrastructure as a Service providers offer applications based in Docker containers deployed on virtual machines. Only a few bring Infrastructure as a Service on a bare metal container infrastructure. In the private cloud scenario, however, it hasn’t had a wide acceptance. Private cloud managers, like OpenStack, OpenNebula and Eucalyptus, don’t offer good support for it. OpenNebula is a flexible cloud manager, which has been gaining a lot of market over the last years, so it seemed a good idea to strengthen the operating system virtualization support in this cloud manager. This will contribute to achieve better interoperability, performance and scalability in OpenNebula clouds. Therefore, the objective of the present work was to implement a driver to support Linux Containers for OpenNebula. The driver has several features such as: the ability to deploy containers on File Systems, on Logical Volume Managers and on Ceph; it’s able to attach and detach network interface cards and disks while the container is on; and it’s able to monitor and limit container’s resources usage.
