Kubeflow Operators

Introduction

Charmed Kubeflow is a full set of Kubernetes operators to deliver the 30+ applications and services that make up the latest version of Kubeflow, for easy operations anywhere, from workstations to on-prem, to public cloud and edge.

A charm is a software package that includes an operator together with metadata that supports the integration of many operators in a coherent aggregated system.

This technology leverages the Juju Operator Lifecycle Manager to provide day-0 to day-2 operations of Kubeflow.

Visit charmed-kubeflow.io for more information.

Install

For any Kubernetes, follow the installation instructions.

Testing

To deploy this bundle and run tests locally, do the following:

  1. Set up Kubernetes, Juju, and deploy the bundle you're interested in (kubeflow or kubeflow-lite) using the installation guide. This must include populating the .kube/config file with your Kubernetes cluster as the active context. Do not create a namespace with the same name as the username, this will cause pipelines tests to fail. Beware of using admin as the dex-auth static-username as the tests attempt to create a profile and admin conflicts with an existing default profile.

  2. Install test prerequisites:

    sudo snap install juju-wait --classic
    sudo snap install juju-kubectl --classic
    sudo snap install charmcraft --classic
    sudo apt update
    sudo apt install -y libssl-dev firefox-geckodriver
    sudo pip3 install tox
    sudo pip3 install -r requirements.txt
  3. Run tests on your bundle with tox. As many tests need authentication, make sure you pass the username and password you set in step (1) through environment variable or argument, for example:

    • full bundle (using command line arguments):
      tox -e tests -- -m full --username user123@email.com --password user123
      
    • lite bundle (using environment variables):
      export KUBEFLOW_AUTH_USERNAME=user1234@email.com
      export KUBEFLOW_AUTH_PASSWORD=user1234
      tox -e tests -- -m lite
      

Subsets of the tests are also available using pytest's substring expression selector (e.g.: tox -e tests -- -m full --username user123@email.com --password user123 -k 'selenium' to run just the selenium tests).
