CernVM-FS for Containers

Thursday, October 15, 2020 - 15:00 to 16:00

Delivering complex software stacks across a worldwide distributed system is a challenge in high-throughput scientific computing. The global-scale virtual file system CernVM-FS distributes more than a billion software binaries to hundreds of thousands of machines around the world.

Learning goal: 

In this webinar, we will present the latest developments with regard to CernVM-FS container integration. Containers and CernVM-FS team up nicely: containers provide the isolation capabilities that decouple the application stack from the underlying platform and CernVM-FS provides efficient distribution means for the containerized software binaries. Containers are an enabling technology to harness opportunistic resources and HPC facilities. CernVM-FS enables the use of such resources at scale. In this webinar, we will show how existing repositories can be used with several popular container runtimes, such as docker, podman, singularity, and kubernetes.  We will also show how operating system containers themselves can be efficiently distributed through CernVM-FS. Lastly, we will highlight an upcoming new way of publishing content from within a container.  This makes it easy to set up, build and test and deploy-to-cvmfs pipelines on kubernetes.
