The container workshop will give an introduction to Docker & Apptainer which are great components to achieve portability and reproducibility of your analysis. You will learn how to use containers and how to build a container from scratch, share it with others and how to re-use and modify existing containers. After an extensive explanation on Docker containers, the Apptainer application, previously Singularity, and its use in the HPC will be highlighted as well. This course is part of a micro-credential track; a micro-credential has the added value of being like a mini-diploma. When following the full track, you will be able to improve the reproducibility of your research. Check this opportunity: Reproducible Data Analysis: an Essential Capability in Modern Science
