We describe the construction, deployment, and ongoing use and development of Project Pythia’s persistent BinderHub (https://binder.projectpythia.org) platform on Jetstream2, using a community-tested OpenStack / Kubernetes workflow developed by Dr. Andrea Zonca at the San Diego Supercomputer Center and operated and maintained by Kevin Tyle of University at Albany-SUNY on behalf of Project Pythia. Project Pythia (https://projectpythia.org) is an open access educational initiative established with funding from the U.S. National Science Foundation. Its mission is to help students and scientists enhance their skills and adopt best practices using the tools and technologies of open science. As part of the Pangeo community, Project Pythia primarily focuses on the Pangeo stack, which includes cloud computing, Jupyter technologies, GitHub, and various software packages in the Scientific Python ecosystem, centered around Xarray. Project Pythia offers a wide range of open access content, such as datasets, software, tutorials, and annotated real-world workflows presented in the form of Jupyter Books. Following the presenters’ initial development efforts on Jetstream2 during summer 2022, in May 2023, Project Pythia was awarded a Discover ACCESS allocation that deployed a persistent and performant BinderHub instance to support our community educational Pythia Cookbook (https://cookbooks.projectpythia.org) initiative. This ongoing service ensures continuous open access to high quality, tested, and reproducible tutorial and training material for geoscientific workflows, while growing our user-contributor community. The BinderHub has also powered the following workshops and tutorials: Pythia Cookoff, June 2023, Boulder AMS Open Radar Short Course, August 2023, Minneapolis Scientific data workshop with Python and R - AtmosCol 2023, October 2023, Colombia AGU Python Visualization Workshop, Dec. 2023, San Francisco AMS Python Visualization Short Course, January 2024, Baltimore ARM Open Science Summer School, May 2024, Cleveland Pythia Cookoff, June 2024, Boulder At each event, our BinderHub seamlessly served all attendees, which typically ranged between 30 and 70.
