CVMFS

If your workflow needs to access CVMFS filesystem, you should provide a cvmfs sub-clause of the resources clause that would list all the CVMFS volumes that would be mounted for the workflow execution. For example:

    workflow:
      type: serial
      resources:
        cvmfs:
          - fcc.cern.ch
      specification:
        steps:
          - environment: 'docker.io/cern/slc6-base'
            commands:
            - ls -l /cvmfs/fcc.cern.ch/sw/views/releases/

Please note that CVMFS is automatically available for HTCondor and Slurm compute backend jobs and there is no need to specify CVMFS requirement in the workflow specification.
