User Guide · Tutorials · Contribution Guide

🚀 Quick Start

To get the hang of Python SDK, refer to the Getting Started tutorial before exploring the examples.

User Guide section has code examples, tips, and tricks that showcase the usage of Flyte features and integrations.

Tutorials section has real-world examples, ranging from machine learning training, data processing to feature engineering.

📖 Contribution Guide

Flytesnacks currently has all examples in Python (Flytekit Python SDK). In the future, Java examples employing Flytekit JAVA will be out.

Here are the setup instructions to start contributing to flytesnacks repo:

💻 Contribute to examples

1. Determine where to put your new code:

   • Core

     Contains examples that demonstrates functionality available within core flytekit. These examples should be runnable locally.

   • Integrations

     Contains examples that leverage one or more of the available plugins.

   • Case Studies

     Contains examples that demonstrates usage of Flyte to solve real world problems. These are more generally more complex examples that may require extra setup or that can only run on larger clusters.

2. Create a directory After determining where to put your example, create a directory under the appropriate parent directory. Each example directory should contain:

   • Dockerfile
   • Makefile
   • README.rst
   • init.py
   • requirements.in
   • sandbox.config It might be easier to copy one of the existing examples and modify it to your needs.

3. Add it to CI Examples are references in this github workflow Add a new entry under strategy -> matrix -> directory with the name of your directory as well as its relative path.

4. Test your code!

   • If the Python code can be run locally, just use python <my file> to run it.
   • If the Python code has to be tested in a cluster:
     • Install flytectl by running brew install flyteorg/homebrew-tap/flytectl. Learn more about install and configuration of flytectl
     • Run the make start command in the root directory of the flytesnacks repo
     • Visit https://localhost:30081/console to view the Flyte console consisting of the examples present in flytesnacks/cookbook/core directory
     • To fetch new dependencies and rebuild the image, run make register
     • If examples from a different directory (other than core) have to registered, enter the sandbox first: make shell and then run make -C <directory> register.
