DAPHNE4NFDI Software practice workshop @ EuXFELIn-Person Event

24 Feb 2025, 12:00 → 25 Feb 2025, 14:00 Europe/Berlin

Groundfloor (Building XHO)

This workshop aims to give an introduction to good software development and deployment practice with a focus on continuous integration and containerisation. Somewhat more advanced topics like integration of CI workflows with container deployment and use of Kubernetes for orchestration will also be addressed.

Tutorial talks ranging from instructive generalisation to concrete use cases of "how it is done at institution X" are complemented by hands-on exercises to apply the concepts learned.
