Use a Databricks workspace to develop a Kedro project

This guide demonstrates a workflow for developing Kedro projects on Databricks using only a Databricks Repo and a Databricks notebook. You will learn how to develop and test your Kedro projects entirely within the Databricks workspace.

This method of developing a Kedro project for use on Databricks is ideal for developers who prefer developing their projects in notebooks rather than an in an IDE. It also avoids the overhead of setting up and syncing a local environment with Databricks. If you want to take advantage of the powerful features of an IDE to develop your project, consider following the guide for developing a Kedro project for Databricks using your local environment.

In this guide, you will store your project’s code in a repository on GitHub. Databricks integrates with many Git providers, including GitLab and Azure DevOps. The steps to create a Git repository and sync it with Databricks also generally apply to these Git providers, though the exact details may vary.

What this page covers

This tutorial introduces a Kedro project development workflow using only the Databricks workspace. The main steps in this workflow are:


Set up your project

Install Kedro in a new virtual environment

In your local development environment, create a virtual environment for this tutorial. Any environment management system can be used, though the following commands use Conda:

conda create --name iris-databricks python=3.10

Once it is created, activate it:

conda activate iris-databricks

With your Conda environment activated, install Kedro:

pip install kedro

Create a new Kedro project

Create a Kedro project with the databricks-iris starter using the following command in your local environment:

kedro new --starter=databricks-iris

Name your new project iris-databricks for consistency with the rest of this guide. This command creates a new Kedro project using the databricks-iris starter template.


If you are not using the databricks-iris starter to create a Kedro project, and you are working with a version of Kedro earlier than 0.19.0, then you should disable file-based logging to prevent Kedro from attempting to write to the read-only file system.

Create a GitHub repository

Now you should create a new repository in GitHub using the official guide. Keep the repository private and don’t commit to it yet. For consistency with the rest of this guide, name your GitHub repository iris-databricks.

Create a GitHub personal access token

To synchronise your project between your local development environment and Databricks, you will use a private GitHub repository, which you will create in the next step. For authentication, you will need to create a GitHub personal access token. Create this token in your GitHub developer settings.

The main steps are:

  • Verify your email and navigate to “Settings” under your profile photo.

  • Select “Developer settings” then “Fine-grained tokens” and click on “Generate new token”.

  • Select a name and expiration time for your token, choose an expiration time.

  • Select which repositories your token will allow access to and define the token permissions.

Push your Kedro project to the GitHub repository

At the command line, initialise Git in your project root directory:

# change the directory to the project root
cd iris-databricks/
# initialise git
git init

Then, create the first commit:

# add all files to git staging area
git add .
# create the first commit
git commit -m "first commit"

To connect to your GitHub repository from your local environment, use one of two options:

With one of these two options chosen, run the following commands:

# configure a new remote
# for HTTPS run:
git remote add origin<username>/iris-databricks.git
# or for SSH run:
git remote add origin<username>/iris-databricks.git

# verify the new remote URL
git remote -v

# push the first commit
git push --set-upstream origin main

Create a repo on Databricks

You will now create a repo on Databricks using the following steps:

  1. Create a new repo:

  • Navigate to the Repos tab in the Databricks workspace UI and click Add Repo.

  • Keep the Add Repo popup open for the following steps.

Create a new Databricks repo

  1. Specify your GitHub repo:

  • In the Git repository URL field, enter your GitHub repository’s URL. This will automatically populate the Git provider and Repository name fields also.

Specify GitHub repo details

  1. Authenticate Databricks with GitHub:

  • Click on the Git credential field.

  • In the Git provider field, select GitHub in the dropdown menu.

  • In the Git provider username or email field, enter the username or email address of your GitHub account.

  • In the Token field, enter your GitHub personal access token.

  • Click the Save button to save your new Git credential.

Authenticate Databricks with GitHub

  1. Finish the Repo creation process:

  • Click Create Repo. Your GitHub repository is cloned to Databricks and the popup window closes.

Create a new Databricks notebook

Now that your project is available in a Databricks Repo, you can run it on a cluster using a notebook.

To run the Python code from your Databricks repo, create a new Python notebook in your workspace. Name it iris-databricks for traceability and attach it to your cluster:

Create a new notebook on Databricks

Copy project data to DBFS using dbutils

On Databricks, Kedro cannot access data stored directly in your project’s directory. As a result, you’ll need to move your project’s data to a location accessible by Databricks. You can store your project’s data in the Databricks File System (DBFS), where it is accessible.

A number of methods exist for moving data to DBFS. However, in this guide, you will use your new notebook and dbutils.

To move your locally stored data to DBFS, open your iris-databricks notebook and in the first cell enter the following python code:


Run this cell to copy the complete directory and its contents from your Repo to DBFS.

To ensure that your data was copied correctly, you can list the contents of the destination directory in DBFS. Create a new cell underneath the first cell and enter the following code:"dbfs:/FileStore/iris-databricks/data")

Run this command to displays the contents of your project’s data/ directory. You can expect to see the following structure:

[FileInfo(path='dbfs:/FileStore/iris-databricks/data/01_raw', name='01_raw', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/02_intermediate', name='02_intermediate', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/03_primary', name='03_primary', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/04_feature', name='04_feature', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/05_model_input', name='05_model_input', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/06_models', name='06_models', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/07_model_output', name='07_model_output', size=...),
 FileInfo(path='dbfs:/FileStore/iris-databricks/data/08_reporting', name='08_reporting', size=...)]

After these cells have successfully run, you should comment the code inside them so their operations are not unnecessarily performed during notebook runs. The cells should appear as below:

Cell 1:

#    "file:///Workspace/Repos/<databricks_username>/iris-databricks/data",
#    "dbfs:/FileStore/iris-databricks/data",
#    recurse=True,

Cell 2:"dbfs:/FileStore/iris-databricks/data")

Run your project

Create four new cells inside your notebook. You will fill these cells with code that runs your project. When copying the following code snippets, remember to replace <databricks_username> with your username on Databricks such that project_root correctly points to your project’s location.

  1. Before you import and run your Python code, you’ll need to install your project’s dependencies on the cluster attached to your notebook. Your project has a requirements.txt file for this purpose. Add the following code to the first new cell to install the dependencies:

%pip install -r "/Workspace/Repos/<databricks_username>/iris-databricks/requirements.txt"
  1. To run your project in your notebook, you must load the Kedro IPython extension. Add the following code to the second new cell to load the IPython extension:

%load_ext kedro.ipython
  1. Loading the extension allows you to use the %reload_kedro line magic to load your Kedro project. Add the following code to the third new cell to load your Kedro project:

%reload_kedro /Workspace/Repos/<databricks_username>/iris-databricks
  1. Loading your Kedro project with the %reload_kedro line magic will define four global variables in your notebook: context, session, catalog and pipelines. You will use the session variable to run your project. Add the following code to the fourth new cell to run your Kedro project:

After completing these steps, your notebook should match the following image:

Databricks completed notebook

Run the completed notebook using the Run All button in the top right of the UI:

Databricks notebook run all

On the first run of your Kedro project, you will be prompted to consent to analytics, type y or N in the field that appears and press Enter:

Databricks notebook telemetry consent

You should see logging output while the cell is running. After execution finishes, you should see output similar to the following:

2023-06-06 12:55:22,705 - iris_databricks.nodes - INFO - Model has an accuracy of 0.953 on test data.
2023-06-06 12:55:22,709 - kedro.runner.sequential_runner - INFO - Completed 3 out of 3 tasks
2023-06-06 12:55:22,709 - kedro.runner.sequential_runner - INFO - Pipeline execution completed successfully.

Modify your project and test the changes

Now that your project has run successfully once, you can make changes using the Databricks UI. In this section, you will modify the project to use a different ratio of training data to test data and check the effect of this change.

Modify the training / test split ratio

The databricks-iris starter uses a default 80-20 ratio of training data to test data when training the classifier. You will edit this ratio to 70-30 and re-run your project to view the different result.

In the Databricks workspace, click on the Repos tab in the side bar and navigate to <databricks_username>/iris-databricks/conf/base/. Open the file parameters.yml by double-clicking it. This will take you to a built-in file editor. Edit the line train_fraction: 0.8 to train_fraction: 0.7, your changes will automatically be saved.

Databricks edit file

Re-run your project

Return to your Databricks notebook. Re-run the third and fourth cells in your notebook (containing the code %reload_kedro ... and The project will now run again, producing output similar to the following:

2023-06-06 12:56:14,399 - iris_databricks.nodes - INFO - Model has an accuracy of 0.972 on test data.
2023-06-06 12:56:14,403 - kedro.runner.sequential_runner - INFO - Completed 3 out of 3 tasks
2023-06-06 12:56:14,404 - kedro.runner.sequential_runner - INFO - Pipeline execution completed successfully.

You can see that your model’s accuracy has changed now that you are using a different classifier to produce the result.


If your cluster terminates, you must re-run your entire notebook, as libraries installed using %pip install ... are ephemeral. If not, repeating this step is only necessary if your project’s dependencies change.

Managing your Databricks Repo

Your Databricks Repo now has untracked changes that are not synced with your GitHub repository. To track your changes and sync your Repo, you can use the corresponding Git operations in Databricks Repos. A basic overview of the steps to achieve this is:

  • Commit your changes in your Databricks Repo.

  • Push the changes to the GitHub repository linked to your Databricks Repo.

  • Check that the latest commits are visible in your GitHub repository.


This guide demonstrated a development workflow on Databricks using only the Databricks workspace. This approach is ideal for users who prefer to develop using notebooks and avoids having to set up and sync a local environment with Databricks.
