OpenNebulaConf 2014 - Lightning talk: Managing Docker Containers with OpenNebula - Marco Mancini
0 likes601 views
The document discusses managing Docker containers with OpenNebula. OpenNebula can orchestrate both virtual machines and Docker containers on a single host. Docker containers offer lightweight virtualization and fast provisioning. The document proposes integrating Docker containers into OpenNebula's infrastructure for tasks like networking, storage, monitoring and lifecycle management of containers.

OpenNebula as an Orchestrator of VM and Containers
An Host can provide both VMs and Containers (e.g. KVM + docker engine)

- 2. About CMCC & SCO ●CMCC is a non-profit research Institution ●Established in 2005, with the financial support of the Italian Ministry of Education, University and Research, the Ministry of the Environment, Land and Sea and the Ministry of Economy ●CMCC manages and promotes scientific and applied activities in the field of international climate change research ●CMCC involves and links private and public institutions, jointly investigating multidisciplinary topics related to climate science research Scientific Computing & Operations ●Scientific Data Management ●High End Computing ●High Performance Computing System Management Current Cloud Computing Activities at SCO ●Big Data analytics framework for eScience (OPHIDIA) to study Climate change and biodiversity (EUBrazilCC project (2014-2016), Ignacio Blanquer, UPV (Spain), Francisco Brasileiro, UFCG, Brasil) ●Different deployment scenarios using OpenNebula
- 3. Proposed feature/activity Dockerfile: recipe to build a container Execution is fast and lightweight: processes are isolated but ran straight on the host, CPU, memory, network and disk/io performance almost equal to native performance Containers: lightweight VMs Own process space Own network space Can run stuff as root Can have its own /sbin/init Image: basis for the container Docker Engine: Commoditize LXC Uses copy-on-write for quick provisioning Runs as a daemon Interaction with CLI and REST API Registry: share/store images Integration of Docker containers into OpenNebula Use Case: OneFlow for quick provisioning and dynamic scaling of OPHIDIA Docker: Build, Ship and Run Any App, Anywhere ●Package your application in a container ●Move the container from one machine to another ●Execute that container anywhere Docker Components Data Volume: persistent and/or shared data
