— Wiktionary

Turn the krank on your data reduction tasks with the magic of containers.

Usage via Docker

TODO

Log in to Ocelote or El Gato
module load singularity to make the singularity command available
Request a large temporary workspace with xdisk -c create -m 1000 and then cd /xdisk/$USER so that the image builds outside your (somewhat small) home directory quota
singularity build krank.img docker://magaox/krank
Copy the images you want to analyze into /xdisk/$USER with rsync (e.g. rsync ./data filexfer.hpc.arizona.edu:/xdisk/yournetid/data)

UA HPC has a storage quota and a file count quota. Trying to retain intermediate files will quickly exhaust the latter, so be sure to delete those after combining.
Singularity only has two (useful) users, root at build time (as whom all build commands are run) and $USER (i.e. you) at run time.
UA-specific HPC network filesystem mount points are present as empty directories in the image to silence Singularity warnings (and let you access HPC shares when run on UA HPC)

In Singularity: singularity shell krank.img
In Docker: docker run -it magaox/krank bash (After commenting out the entrypoint and rebuilding)
