Kubeflow Pipelines meets Tekton and Watson
Create your machine learning pipeline using Kubeflow Pipelines DSL and compile it to Tekton YAML.
More machine learning models need to be deployed in production in a faster, repeatable, and consistent manner — and with the right governance.
In March 2018 at the Strata Data Conference, IBM VP Dinesh Nirmal noted a common refrain) in the machine learning echelon, “The story of enterprise Machine Learning — It took me 3 weeks to develop the model. It’s been >11 months, and it’s still not deployed.”
Echoing this sentiment, Forrester states in their 2020 report, “A top complaint of data science, application development and delivery (AD&D) teams, and, increasingly, line-of-business leaders is the challenge in deploying, monitoring, and governing machine learning models in production. Manual handoffs, frantic monitoring, and loose governance prevent organizations from deploying more AI use cases.”
MLOps and Kubeflow Pipelines speed deployment
To solve this problem, data scientists, data engineers, and DevOps folks worked together to move this discipline forward with the rigor of engineering as opposed to science. The MLOps and DataOps domains rose based on this demand and need, and consequently data and machine learning pipelines became a primary vehicle to drive these domains.
Kubeflow became a leading solution to address MLOps needs. Kubeflow is an end-to-end machine learning platform that is focused on distributed training, hyperparameter optimization, production model serving and management, and machine learning pipelines with metadata and lineage tracking.
Needless to say, Kubeflow Pipelines became a primary vehicle to address the needs of both DevOps engineers and data scientists.
- For DevOps folks, Kubeflow taps into the Kubernetes ecosystem, leveraging its scalability and containerization principles
- For Data Scientists, Kubeflow Pipelines offers a Python interface to define and deploy Pipelines, enabling metadata collection and lineage tracking
- For DataOps folks, Kubeflow Pipelines brings in ETL bindings to participate more fully in collaboration with peers by providing support for multiple ETL components and use cases.
With IBM’s standardization on Kubernetes and leadership in the Kubeflow community, IBM has adopted Kubeflow Pipelines as the natural choice to define our strategy for end-to-end data and machine learning pipelines.
Announcing: Kubeflow Pipelines on Tekton
The decision to adopt Kubeflow Pipelines on our side came with an internal requirement to redesign Kubeflow Pipelines to run on top of Tekton (a Kubernetes-native CI/CD engine) instead of Argo. Tekton provides Kubernetes-style resources for declaring CI/CD-style pipelines, and introduces several new Custom Resource Definitions (CRDs) including Task, Pipeline, TaskRun, and PipelineRun. Within IBM, we have standardized on Tekton as a cloud CI/CD engine, and OpenShift Pipelines is based on Tekton. Additionally, Tasks in Tekton can be managed and executed independently of pipelines, which is valuable for us.
Given the strategic and technical alignment with Tekton, it was a natural fit for our team to rewrite and run Kubeflow Pipelines on top of Tekton. As we set out to design and execute this work, we got great support through Google Kubeflow Pipelines team, CD Foundation MLOps Sig, and Red Hat. After an extensive effort, we have Kubeflow Pipelines running on Tekton end-to-end and available in open source. Read our design document to understand our process and requirements.
With this milestone, you can:
- Create your pipeline using Kubeflow Pipelines DSL and compile it to Tekton YAML.
- Upload the compiled Tekton YAML to the Kubeflow Pipeline engine (API and UI), and run end-to-end with logging and artifacts tracking enabled.
If you are using Kubeflow Pipelines in the community with the open source codebase, your experience remains the same! You can use:
- Python SDK published by us to compile your Pipelines Python DSLs
- On the Kubeflow Pipelines UI, you get the same KFP DAG experience, backed by Tekton YAML
Additionally, real-time log streaming, artifact tracking, and lineage tracking work fully as needed.
Kubeflow Pipelines with Tekton on Red Hat OpenShift and IBM Cloud Kubernetes Service (IKS)
OpenShift Pipelines provides a cloud-native CI/CD on OpenShift, automating build, test, and deployment of applications across on-premises and public cloud platforms. Follow the instructions at Deploy Kubeflow Pipelines with Tekton backend on OpenShift Container Platform to see how to run Kubeflow Pipelines with Tekton on OpenShift. Depending on your situation, you can choose between the two approaches:
- Leverage OpenShift Pipelines (built on Tekton) as the core.
- Install Tekton as part of a deployment.
The next step for us is to integrate Kubelflow Pipelines with Tekton into Red Hat’s OpenDataHub project given its charter as an open source AI/ML platform on OpenShift.
In addition, with the upcoming Kubeflow 1.2 release, Kubeflow Pipelines with Tekton is available for deployment on IBM Cloud Kubernetes Service and is included by default with Kubeflow deployment on IBM Cloud.
Launching soon: Watson AI Platform Pipelines
Taking this further, we are launching Watson AI Platform Pipelines, end-to-end machine learning and data pipelines, on this stack. We are adding additional features to make it easier to build pipelines with drag-and-drop canvas, pipeline components registry, production-grade logging and governance capabilities by virtue of integration with IBM Watson Studio, Watson AutoAI, Watson Knowledge Catalog, Notebooks, and others. Stay tuned, provide feedback, and request early access!
