Lightning talk from the OpenStack NYC meetup on October 8, 2014. http://bit.ly/ibm-os-meetup By Paolo Dettori and Seetharami Seelam We will describe our experiences running Docker containers in a multi-node OpenStack environment deployed on public cloud infrastructure. From this we will show DockerCloud, providing IaaS like capabilities for Docker containers as well as container orchestration on OpenStack. The content of this talk is a statement from the IBM Research division, not IBM product divisions, and is not a statement from IBM regarding its plans, directions or product intents. Any activities described by this talk are subject to change.
