What is Rclone?

From https://hub.docker.com/r/rclone/rclone:

Rclone (“rsync for cloud storage”) is a command line program
to sync files and directories to and from different cloud storage providers.

Overview

You will install rclone on your local computer. Through the command rclone config, you will create a credential file for rclone to connect to your WashU Box on your local computer. By copying the file to your home directory on RIS compute1 client, you will be able to access your Box storage through your rclone container on a compute1 exec node.

Prerequisites
