Typical Kedro workflow

Development workflow

When building a Kedro project, you will typically follow a standard development workflow:


1. Set up the project template

  • Create a new project with kedro new
  • Install dependencies with kedro install
  • Configure the following in the conf folder:
    • Logging
    • Credentials
    • Any other sensitive / personal content

2. Set up the data

  • Add data to the data/ folder
  • Reference all datasets for the project in conf/base/catalog.yml

3. Create the pipeline

  • Create the data transformation steps as Python functions
  • Construct the pipeline by adding your functions as nodes
    • Specify inputs and outputs for each node
  • Choose how to run the pipeline: sequentially or in parallel

4. Package the project

  • Build the project documentation
  • Package project into Python wheels or eggs for distribution

Git workflow

Creating a project repository

Kedro doesn’t require git and can work without any source control management system. However, we recommend keeping your work in a git repository. As a start you can follow one of the most popular git workflows known as Gitflow.

To use git, if you don’t have a local repository for your project already, create it with these commands:

git init
git remote add origin https://github.com/<your-repo>
Note: These commands must be issued from within the project directory.

Submitting your changes to GitHub

As you work on a project, you will periodically want to save your changes. If you are working as part of a team, we suggest developing your code on a branch and creating pull requests to submit it to your develop or master branch:

# create a new feature branch called 'feature-project-template'
git checkout -b feature/project-template
# stage all the files you have changed
git add .
# commit changes to git with an instructive message
git commit -m 'Create project template'
# push changes to remote branch
git push origin feature/project-template

It isn’t necessary to branch, but if everyone in a team works on the same branch (e.g. master), you may have to resolve merge conflicts more often. Here is an example of working directly on master:

# stage all files
git add .
# commit changes to git with an instructive message
git commit -m 'Create project template'
# push changes to remote master
git push origin master
