Teaching Container-Based DevOps Practices.

We present the design of a online course that focuses on container-based virtualization as part of the DevOps toolchain. In addition, we outline the professional background of participants taking the course, and describe how this affects perceived previous knowledge of DevOps. We found out that the self-evaluated conceptual understanding of DevOps topics is nearly equal regardless of the participants professional identity (e.g., student or developer). However, there are significant differences in how much participants have used tools like Docker before. We conclude that there is a clear need for lifelong learning among software engineering professionals as (future) developers often struggle in operations related skills such as command line or networking.
