Rucio JupyterLab Extension

This is a JupyterLab extension that integrates with Rucio - Scientific Data Management to allow users to access some of Rucio's capabilities directly from the JupyterLab interface.

This extension is composed of a Python package named rucio_jupyterlab for the server extension and a NPM package named rucio-jupyterlab for the frontend extension.

Requirements

• JupyterLab >= 3.0
• Rucio Server >= 1.28

Install

Note: You will need NodeJS to install the extension.

pip install rucio-jupyterlab

If you are going to run the extension in Download mode, you will also need to install libraries required by the RSE downloaders. For instance, gfal2, which is available in EPEL or conda-forge.

Additionally, you need to have grid-proxy-init or voms-proxy-init executable. You can do so by installing voms-clients-java.

$ apt install voms-clients-java
$ conda install -c conda-forge python-gfal2
# OR
$ yum install epel-release
$ yum install gfal2-all gfal2-python voms-clients-java

Restart your JupyterLab instance afterwards to load the server extension.

Configuration

See CONFIGURATION.md

Quick Setup using Docker

This repository comes with a Docker image of jupyter/scipy-notebook installed with the extension.

To run the image, use the following command.

Replica Mode

$ docker run -d -p 8888:8888 \
    -e RUCIO_MODE=replica \
    -e RUCIO_WILDCARD_ENABLED=<true = 1, false = 0> \
    -e RUCIO_BASE_URL=<Rucio base URL> \
    -e RUCIO_AUTH_URL=<Rucio auth URL (if any)> \
    -e RUCIO_DESTINATION_RSE=<destination RSE> \
    -e RUCIO_DISPLAY_NAME=<instance display name> \
    -e RUCIO_NAME=<instance name> \
    -e RUCIO_SITE_NAME=ROAMING \
    -e RUCIO_VO=def \
    -e RUCIO_PATH_BEGINS_AT=<path begins at> \
    -e RUCIO_RSE_MOUNT_PATH=<mount path> \
    -v <host folder>:<container folder> \
    rucio/jupyterlab:latest

<host folder> is a folder in the host that is mounted to a Rucio Storage Element via FUSE. <container folder> is a folder accessible from the notebook that is mounted to the host folder.

Download Mode

$ docker run -d -p 8888:8888 \
    -e RUCIO_MODE=download \
    -e RUCIO_WILDCARD_ENABLED=<true = 1, false = 0> \
    -e RUCIO_BASE_URL=<Rucio base URL> \
    -e RUCIO_AUTH_URL=<Rucio auth URL (if any)> \
    -e RUCIO_DISPLAY_NAME=<instance display name> \
    -e RUCIO_NAME=<instance name> \
    -e RUCIO_SITE_NAME=ROAMING \
    -e RUCIO_VO=def \
    -e RUCIO_VOMS_ENABLED=<true = 1, false = 0> \
    -e RUCIO_VOMS_VOMSES_PATH=<path to vomses file (optional)> \
    -e RUCIO_VOMS_CERTDIR_PATH=<path to certdir (optional)> \
    -e RUCIO_VOMS_VOMSDIR_PATH=<path to vomsdir (optional)> \
    -e RUCIO_CA_CERT=/certs/rucio_ca.pem \
    -v <path to Rucio CA PEM file>:/certs/rucio_ca.pem \
    rucio/jupyterlab:latest

Follow the configuration guide for details of the parameters.

Troubleshoot

If you are seeing the frontend extension but it is not working, check that the server extension is enabled:

jupyter serverextension list

If the server extension is installed and enabled but you are not seeing the frontend, check the frontend is installed:

jupyter labextension list

If it is installed, try:

jupyter lab clean
jupyter lab build
