Intro to Kubeflow: Katib Training and Certification Recap – May 18, 2022

On May 18th we hosted the “Intro to Kubeflow: Katib Training and Certification” prep course. In this blog post we’ll recap some highlights, plus give a summary of the Q&A from the class.


Congratulations to Samrat Kadge!

The first attendee to earn the “Katib” certificate at the conclusion of the course was Samrat Kadge! A free MiniKF hoodie and shirt are on the way, well done!


First, thanks for voting for your favorite charity!

With the unprecedented circumstances facing our global community, Arrikto is looking for even more ways to contribute. With this in mind, we thought that in lieu of swag we could give course attendees the opportunity to vote for their favorite charity and help guide our monthly donation to charitable causes. The charity that won this workshop’s voting was Every Mother Counts (EMC). The Every Mother Counts is a non-profit organization dedicated to making pregnancy and childbirth safe for every mother. They inform, engage, and mobilize new audiences to take actions and raise funds that support maternal health programs around the world. We are pleased to be making a donation of $100 to them on behalf of the Kubeflow community. Again, thanks to all of you who attended and voted!


What topics were covered in the course?


This initial course aimed to get data scientists and DevOps engineers with little or no experience familiar with the fundamentals of how Kubeflow works.

  • Kubeflow Fundamentals Review
  • Katib Basics
  • Getting Started with Katib
  • Navigating the Katib UI
  • Running Katib Experiments
  • Kale Basics
  • AutoML Example: Kaggle’s OpenVaccine Notebook
  • AutoML Example: Kaggle’s Bulldozers Notebook


What did I miss?

Here’s a short teaser from the 90 minute training. In this video we show you how to use Katib and Kale inside of Kubeflow to perform hyperparameter tuning on Kaggle’s OpenVaccine notebook.

Q&A from the training

Below is a summary of some of the questions that popped into the Q&A box during the course. [Edited for readability and brevity.]


My understanding is that MiniKF is a one-node Kubernetes instance. Does it scale on an on-prem cluster?

Correct, the MiniKF packaged distribution and Arrikto’s Kubeflow as a Service are single VM deployments of Kubeflow. If you are looking for a scalable Kubeflow deployment, we recommend checking out the Enterprise Kubeflow distribution.


I’m wondering if it is possible to train ARIMA models in MiniKF?

If Kubeflow supports ARIMA models, then MiniKF will as well.


Are there any requirements for the docker image used for Katib jobs?

Yes, you learn more under “Running an Experiment” in the official Kubeflow documentation.


Is it possible to access the files, e.g. submission.csv, on the web UI?

Yes. For example, here is the submission.csv viewed from the web UI.
