Containers are a lightweight OS-level virtualization abstraction primarily based on namespace isolation and control groups. In the recent years, container-based virtualization for applications has gained immense popularity thanks to the success of technologies like Docker.  Container packaging mechanisms like Docker, LXD and Rkt, as well as management frameworks like Kubernetes, Mesos, etc., are witnessing widespread adoption in the industry today.  Container technologies have eliminated the feature parity between development and production environment by enabling developers to package applications and their dependencies as a single unit that can be run across diverse operating environments.
Though containers provide a great amount of flexibility and portability from a developer's perspective, there are several important challenges that need to be addressed by the infrastructure provider, in order to run these virtualized applications in a cloud environment. The second workshop on container technologies and container clouds solicits contributions in this area from researchers and practitioners in both the academia and industry. The workshop welcomes submissions describing unpublished research, position papers as well as deployment experiences on various topics related to containers as outlined below.
