Trovi sharing portal¶
Chameleon Trovi is a sharing portal that allows you to share digital research and education artifacts, such as packaged experiments, workshop tutorials, or class materials. Each research artifact is represented as a deposition (a remotely accessible folder) where a user can put Jupyter notebooks, links to images, orchestration templates, data, software, and other digital representations that together represent a focused contribution that can be run on Chameleon. Users can use these artifacts to recreate and rerun experiments or class exercises on a Jupyter Notebook within Chameleon. They can also create their own artifacts and publish them directly to Trovi from within Chameleon’s Jupyter server.
To get started, find the “Trovi” dropdown option under the “Experiment” section of chameleoncloud.org. Once you’re on the Trovi homepage, you’ll see a list of publicly available experiments and other digital artifacts. You can now browse those artifacts or upload your own.
Trovi allows you to browse artifacts, presented in a scrolling list format. On the right hand side, there are multiple filtering options. The “All” choice shows you all of the artifacts you have access to. You can also see how many times people have downloaded and launched your notebook with the icons in the bottom left corner of an artifact.
Some Trovi artifacts are supported by the Chameleon team and are denoted with a small Chameleon logo. You can contact the Help Desk if you are using these artifacts and encounter issues.
Launching an artifact¶
The most powerful feature available via Trovi is the ability to re-launch the available artifacts within Chameleon. Clicking “Launch with JupyterHub” will open a new Jupyter Notebook server with the artifacts downloaded (we support artifacts up to 500MB in total size, please contact the Help Desk if you need more space). The animation below shows how easy it is:
