Managing Jupyter Notebooks on GitLab

Q: Version Control for Jupyter Notebooks in GitLab Repositories

Version Control for Jupyter Notebooks in GitLab Repositories

To manage version control for Jupyter Notebooks in GitLab repositories using Pulumi, you can use the gitlab.RepositoryFile resource from the Pulumi GitLab package. This resource allows you to create, update, and delete files in your GitLab repository. By using it, you can programmatically upload Jupyter Notebooks (.ipynb files) to your GitLab repository and maintain their versions as if you were using Git commands.

In the following Pulumi program, I'll demonstrate how to create a new GitLab project, and then add a Jupyter Notebook to the project's repository. We'll create a simple .ipynb file content as an example. For a real scenario, you would probably read the content of a .ipynb file from disk.

Here's how you would write the program:

import pulumi
import pulumi_gitlab as gitlab

# Create a new GitLab project.
project = gitlab.Project("jupyter-notebook-project",
                         description="Project to store Jupyter Notebooks",
                         visibility_level="private")

# Content of Jupyter Notebook as a string. Normally, you would read this from a file.
notebook_content = """
{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": 1,
   "metadata": {},
   "outputs": [],
   "source": [
    "print('Hello, Pulumi and GitLab!')"
   ]
  }
 ],
 "metadata": {
  "kernelspec": {
   "display_name": "Python 3",
   "language": "python",
   "name": "python3"
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 3
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython3",
   "version": "3.8.1"
  }
 },
 "nbformat": 4,
 "nbformat_minor": 2
}
"""

# Upload the Jupyter Notebook to the GitLab repository.
notebook_file = gitlab.RepositoryFile("jupyter-notebook-file",
                                      project=project.id,
                                      file_path="notebooks/example-notebook.ipynb",
                                      content=notebook_content,
                                      branch="master",
                                      author_email="example@example.com",
                                      author_name="Example Author",
                                      commit_message="Add example Jupyter Notebook")

# Export the URL of the GitLab project.
pulumi.export('project_url', project.web_url)

In this program:

We're first creating a new GitLab project specifically for storing Jupyter Notebooks using the gitlab.Project resource. The project is set to 'private', but you can adjust the visibility as needed.
We create a string that represents the content of a simple Jupyter Notebook. Normally, you would load the actual content from a .ipynb file using file I/O functions in Python. This is just a JSON structure that Jupyter uses to define the notebook and its cells.
We then create a gitlab.RepositoryFile resource, which represents the Jupyter Notebook file within the GitLab repository of the project. We set project to the ID of the created project, set the file_path to where we want the file to reside in the repository, and provide the file's content.
Lastly, we export the URL of the project, so you can quickly access it from your Pulumi output.

To run this Pulumi program, you would first set up Pulumi and configure it with your GitLab credentials. Save this code in a __main__.py file, initialize a new Pulumi stack, and run pulumi up. Pulumi will then execute the code and apply the changes to your GitLab account, creating the project and file as specified.

Remember to replace example@example.com and Example Author with your actual GitLab email and name, and to provide real content for the Jupyter Notebook.
