Run your workflow on JupyterHub

JupyterFlow

Run your workflow on JupyterHub!

What is JupyterFlow?

Run Argo Workflow on JupyterHub with single command.

• No Kubernetes knowledge (YAML) needed to run.
• No container image build & push or deploy.
• Just simply run your workflow with single command jupyterflow.

jupyterflow is a single command that helps user utilize Argo workflow engine without making any YAML files or building containers on JupyterHub. The following jupyterflow command will make sequence workflow for you. That's it!

jupyterflow run -c "python hello.py >> python world.py"

To make parallel workflow, write your own workflow.yaml file.

Problem to solve

• I wanted to train multiple ML models efficiently.
• Using Kubernetes was a good idea, since
  • it is easy to make distributed jobs.
  • it is easy to schedule ML jobs on multiple training server.
  • it has native resource management mechanism.
  • it has good monitoring system.
• But there were some drawbacks.
  • I needed to re-build & re-push image everytime I updated my model. This was painful.
  • People who were not familiar with k8s had a hard time using this method.

JupyterFlow aims to solve this problem. Run your workflow on JupyterHub with single command without Kubernetes & container troublesome task.

Limitation

JupyterFlow only works on JupyterHub deployed on Kubernetes.

• JupyterHub for Kubernetes
• Kubeflow

Therefore, although using JupyterFlow does not require Kubernetes knowledge, setting up JupyterFlow requires Kubernetes understandings(YAML, helm, Service). If you're familiar with Kubernetes, it will not be too hard.

Getting Started

To set up jupyterflow and start running your first workflow, follow the Getting Started guide.
