Mount cvmfs on worker nodes

Requirements

To set cvmfs mountpoints on the worker node you should apply simple changes to the HTCondor HELM values indicated either for DODAS (this guide) or or plain HELM (this other guide).

Configuration

You can simply add the following values to the HELM values file to mount different CVMFS repositories on the WNs:

cvmfs:
    enabled: true 
    image: cloudpg/cvmfs
    tag: k8s-dev
    pullPolicy: IfNotPresent
    replicas: 1

    # List of repos to be mounted
    repoList: ams.local.repo ams.cern.ch sft.cern.ch

    privKey: 
    - name: ams
        filename: ams.local.repo.pub
        path: \"keys/ams.local.repo\"
        content: | 
        -----BEGIN PUBLIC KEY-----
            <CHANGEME>
        -----END PUBLIC KEY-----
    defaultLocalConfig:
    - file: ams.local.repo.conf
        content: |
        CVMFS_SERVER_URL=http://<CHANGEME>/cvmfs/ams.local.repo
        CVMFS_PUBLIC_KEY=/etc/cvmfs/keys/ams.local.repo/ams.local.repo.pub
        CVMFS_HTTP_PROXY=DIRECT
        CVMFS_DEBUGFILE=/tmp/cvmfs_ams_local.log
    - file: ams.cern.ch.conf
        content: |
        CVMFS_SERVER_URL=http://cvmfs-stratum-one.cern.ch/cvmfs/ams.cern.ch
        CVMFS_HTTP_PROXY=DIRECT
        CVMFS_DEBUGFILE=/tmp/cvmfs_ams_cern.log
    - file: sft.cern.ch.conf
        content: |
