Git Repositories

Add your Git repositories to Saturn Cloud

This article describes how use existing git repositories with your Saturn Cloud resources. Saturn Cloud resources have the ability to connect to git repositories which can load the code at resource startup. This document first covers setting up SSH credentials then goes into adding git repositories to Saturn Cloud and finally adding those to resources. When the document refers to git hosts it means services like GitHub, Bitbucket, and GitLab which host git repositories for you.

Set up git SSH Keys

Saturn Cloud supports using SSH keys as a protocol to connect to git repositories, which requires a public key and private key pair shared with Saturn Cloud and your git host. So the first step is sharing the right keys. Thankfully, Saturn Cloud will automatically generate a public/private key pair for you by default, but you can change it as needed.

Go to the Git Repositories tab in Saturn Cloud, at the bottom you’ll see an SSH Keys area, which will first request you create a key with a new Saturn Cloud account. You can generate a public/private key pair within Saturn Cloud or upload your own:

Git SSH key generation

After you have a key pair, take the SSH public key and add it to your git Host to create the secure connection. Refer to your git host for how to do this (for example, here are the directions for GitHub).

Git SSH key UI

There are several adjustments you can make for the SSH key:

  • If you’d like to change the key (either upload a new one or regenerate a key pair in Saturn Cloud), press the Replace Key button.
  • Normally Saturn Cloud will use a single private key for all your repositories. If you have different keys for different repositories, like if you’re using multiple git hosts, you can Set the private keys on a per-repo basis by sliding the Allow Multiple Keys toggle.

Add a Git Repository to Saturn Cloud

Once you’ve set up your SSH keys you can add git repositories to your resources. On the resource page, school to the git repositories section and either add a new repository or choose an existing one. Once the repository is added, you can adjust several properties of it.

Resource git repositories

  • Remote URL: The URL for the repository in the git host (this is the link you’d use when running git clone at terminal)
  • Location: the folder that will store the git repository. This will be a sub folder of /home/jovyan/git-repos/
  • Restart behavior: When a resource restarts, what should happen to the repository? Either have it stay in its current state (good for tasks like exploratory analysis), or have it reset to the default reference (good for systems like deployments where you want to use the latest version). For job and deployment resources this must be recloned on restart.
  • Reference: What branch, commit, or tag to clone when the repository is recloned.

Now, when you log in to your Jupyter server, at the top level of your file system the folder git-repos will contain all the repositories attached to this resource.

If a git repository is removed from a resource via the UI then you will need to manually delete the folder within a Jupyter or RStudio server.

Using git in within your Jupyter Server

To do git commands within Jupyter Server like pushing, pulling, and committing, you can use one of two methods: either from the command line or by using the GUI provided by a JupyterLab plugin:

You can open a terminal window from within the Jupyter server and use git from the command line. First open the launcher by pressing the “+” button:

JupyterLab launcher button

Then select “terminal” to go to the command line of the resource:

New terminal button

Alternatively, you can also use the git functionality built into JupyterLab with a GUI, using the plugin on the left of the screen:

Using git within RStudio server

When using RStudio you can use the RStudio built in git functionality, which defaults to a tab in the upper right hand corner of the IDE. You can also use the terminal to directly run git commands, using the terminal tab in the lower left hand corder of the screen.
