SMACK series: "Introduction to Containers (Docker and Singularity)"
Containers are portable environments that package up code and all its
dependencies so that an application can run quickly and reliably from one
computing environment to another. Most people are probably familiar with full
virtualization environments (such as VirtualBox), so in this talk we will
explain the main differences between full virtualization and containers
(sometimes called light-weight virtualization), and when to use each.
At the same time, not all container technologies have the same goals and/or
approaches. Docker is the most mature container offering, but it is geared
mainly towards micro-services. Singularity is a newer contender, with an
emphasis on mobility of compute for scientific computing. We will introduce both
softwares, showing how to create and use containers with each of them, while
discussing real-life examples of their use.
