Upload data

In RStudio, JupyterLab and VSCode

  • If you are using JupyterLab or VSCode you should be able to load data to the container by simply drag and drop the files to upload in the JupyterLab/VSCode web UI.
  • For RStudio, use the Upload file button in the RStudio web UI to upload files from your computer to the RStudio workspace.
File too big

If those solutions don't work due to the files size, try one of the solutions below.

Copy large files with the terminal

The quickest way to upload large files or folders from a laptop or server to the DSRI is to use the oc command line interface.

Install the client

To install the oc client on your laptop/server, visit the Install the client page

oc cp directly copy, and overwrite existing files, from a laptop or server to an Application pod on the DSRI.

First get the <pod_id> using your application name:

oc get pod --selector app=<my_application_name>

Copy from local to pod

Folders are uploaded recursively by default:

oc cp <folder_to_copy> <pod_id>:<absolute_path_in_pod>
Use absolute path in the pod

You need to provide the absolute (full) path where you want to copy it in the pod. Use your application workspace path, e.g. /home/jovyan for JupyterLab or /home/rstudio for RStudio)

For example:

oc cp my-folder jupyterlab-000:/home/jovyan

You can also use this one-liner to automatically get the pod ID based on your app label:

oc get pod --selector app=<my_application_name> | xargs -I{} oc cp <folder_to_copy> {}:<absolute_path_in_pod>

Copy from pod to local

Just do the inverse:

oc cp <pod_ID>:<path_to_copy> <local_destination>

Download data from SURFdrive

You can download data from your SURFdrive to your pod by creating a public link to the file:

  1. Go to the file in SURFdrive you'd like to share
  2. Click share and the create public link
  3. Fill in a name for the public link (like DSRI). The name does not matter much, but it can help you keep track of the goal of the public link.
  4. Click copy to clipboard
  5. Visit link in browser and copy the direct URL displayed on that page.
  6. Use the direct URL you just copied to download the file using either wget or curl (e.g. "wget")
  7. Revoke link in the SURFdrive portal

Synchronizes files with oc rsync

If you have a lot of large files and/or they are updated regularly, you can use rsync as it synchronizes the files if they already exist, preventing duplication and making synchronization faster. You can also see the progress with rsync which you cannot with cp. And if the upload is stopped for any reason rsync should pick it up from where it stopped (instead of restarting from scratch like oc cp does)


Rsync does not work with symlinks (created with ln -s)

Sync local to pod

oc rsync --progress <folder_to_sync> <pod-id>:<sync_path_in_pod>

You can also use this one-liner to automatically get the pod ID based on your app label:

oc get pod --selector app=<my_application_name> | xargs -I{} oc rsync --progress <folder_to_sync> {}:<absolute_path_in_pod>

Sync pod to local

Again, do the inverse:

oc rsync --progress <pod-id>:<folder_to_sync> <local_destination_to_sync>

More options

You can use more options to improve the upload of large files:

--compresscompress file data during the transfer
--deletedelete files not present in source
--watchWatch directory for changes and resync automatically
