# How to set up a Git Repository via JupyterLab-Gallery

[JupyterLab-Gallery ](https://github.com/nebari-dev/jupyterlab-gallery) is a JupyterLab plugin
that allows users to share a Git Repository. JupyterLab users are presented with a tile in
the JupyterLab launch screen. Users can choose to download the Gallery.

No strong opinions, I am just using the wording of "gallery composed of multiple exhibits" in jupyterlab-gallery and it seems to make more sense here.

Ah, I struggled with this wording - that is perfect!


By default, if no JupyterLab-Gallery items are added to the config, users will not see this section
in the JupyterLab Launcher.

This feature was added to Nebari in the 2024.6.1 release.

## Configure JupyterLb-Gallery

In Nebari, the JupyterLab-Gallery configuration is set in the Nebari configuration, `nebari-config.yaml`.

The configuration is set under the `jupyterlab` section under the subsection `gallery_settings`.
Users may set a title for the Gallery section of the Launcher screen and a destination (i.e. folder)
for the location of the cloned repos.

Several repositories can be configured to display as individual gallery tiles. Under the `exhibits`
section, each repository must have a `title` and a `git` location. There are also several other
optional config options.

Just a note: currently the tiles are designed so that they are most beautiful when there is a description. I would personally say that adding description is recommended, but do not want to push it either.


The configuration is set at two different levels. Top level gallery settings define the title of
the Gallery section and the location in which the repositories are downloaded. The repository
level settings are defined for each repository. The descriptions of each section are described
below.

Not a strong opinion here either

I'm not sure what this is?

Can be used as a link to the examples repository. The idea is to separate the git URL which might contain token (discouraged) from the link shown in the UI (if any).

Can be used as a link to the examples repository.

As far as I can tell, the UI doesn't link to the repository in any way. If I hover the gallery tile, I just have the options to download or go to the folder. Is this link provided to the users somewhere else?

That's correct, it is not available in the UI. For god security practice the git URL is separated from user facing URL even though it is not currently in the UI. My plan was to add a new button with link icon but I guess it is low priority. It would be rather low effort too though.

Alternatively, this can be an URL.

Though base64 encoding the image is probably best practice as it ensures that it will never break.

When you log in using token you need to also pass account. Depending on whether it is GitHub or GitLab it should be a pre-defined string, or any string.

This is defined in https://github.com/nebari-dev/jupyterlab-gallery/blob/ef56fc616bae4ec8305c01e3341b773ca4cfd48f/jupyterlab_gallery/manager.py#L30-L82

You can access the documentation via jupyterlab-gallery --help-all. I will add it to the README.

@krassowski for account, what does that look like in a github and gitlab url?

For example, if I go to "clone from https" on the nebari-dev repo, it gives this url: https://github.com/nebari-dev/nebari.git . Would the account be nebari-dev or is that my username associate with the token?

For gitlab the "clone from https" could looks like this: https://gitlab.<domain>.net/<projectname>/<teamname>/gradient.git. What is the account here?

It is not a part of the URL. It is used during login sequence, the same way as you would login via CLI when issuing say git push on a new machine (by providing a user name and password). Of course you would not because everyone has an SSH key configured instead.

## Using JupyterLab-Gallery

Once the repositories are configured in the Nebari config and redeployed, all users will have
a section on their JupyterLab Launcher screen for the Gallery.

![JupyterLab Gallery tiles on JupyterLab Launcher screen](/img/how-tos/jupyter-gallery-tiles.png)

Each tile points to a different gallery entry in the configuration. The Gallery repositories
will not be downloaded until users trigger the download for each gallery item. To do so, users
will hover over the tile and click the download button.

![JupyterLab Gallery tile on hover for undownloaded repo](/img/how-tos/jupyter-gallery-tile-download.png)

The repository will download to the location specified in the config (in each user's private
space). After the download is complete, hover on the gallery tile present the users with two
new options - the folder icon allows them to jump to the location in the JupyterLab file browser,
and the download button allows them to fetch an updated copy of the repo (if available).
