CVMFS installation on K8s clusters

Currently the most stable solution is the PRP driver https://github.com/PanDAWMS/prp-osg-cvmfs.

• For GKE some configurations are adapted under the gke branch.
• For other clusters tried so far the configuration in the master branch is desired.

Follow the instructions on the README.txt

git clone https://github.com/PanDAWMS/prp-osg-cvmfs.git
cd prp-osg-cvmfs
git checkout gke
cd prp-osg-cvmfs/k8s/cvmfs
cat README.txt

• Run the test job at the end of the instructions to see CVMFS gets mounted on a pod. This test job simply sleeps so you can log in and look around a bit.
