CVMFS - gcp4hep/analysis-cluster GitHub Wiki

CVMFS is installed on the Kubernetes cluster and mounted to the Jupyter notebooks. This allows you to use certain ATLAS files/tools from the Jupyter command line. However note that the available notebook images are Ubuntu based, while the ATLAS SW on CVMFS is built for CentOS/Red Hat, so there are many incompatible packages.

The available repositories are:

• atlas.cern.ch
• atlas-condb.cern.ch
• grid.cern.ch
• sft.cern.ch

:information_desk_person: More testing of the CVMFS setup and configuration of all tools would be desirable.

Setting up ATLAS environment from Jupyter

The basic ATLAS setup (similarly to how it's done on lxplus) is done through:

>> echo $ATLAS_LOCAL_ROOT_BASE/
/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase/
>> source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh

Then you can setup further tools, for example you could setup Rucio to get a list of file replicas. However such interaction will require that you upload a valid proxy to your notebook.
