Explore the integration of CERN's software distribution system with Docker in this informative 19-minute talk. Dive into the CERNVM Filesystem (CVMFS), a scalable and reliable service used for processing and analyzing data from CERN experiments, including the Large Hadron Collider. Learn how physicists are transitioning their workloads to containers and how CVMFS has been integrated into Docker using a Volume plugin. Discover the process of mounting repositories, utilizing tags and hashes for data analysis preservation, and ongoing efforts to optimize data access through Docker storage drivers. Gain insights into CERN's computing infrastructure, the CERN Computing Grid, and various use cases for this integration. The talk covers pluggable images, graph drivers, testing procedures, and results, concluding with a summary and Q&A session.
