Kubeflow 2019 roadmap

The roadmap provides a high level overview of key areas that will likely span multiple releases.

The roadmap provides links to critical user journeys(CUJs) that we want to deliver. A CUJ shows how a user would accomplish some critical task (for example build, train, and deploy a model).

Kubeflow does a major release at the end of every quarter. Minor releases occur as needed to fix important bugs.

For detailed information about what will be in a release look for the issues tagged "area/X.Y.Z".

Kubeflow 0.6

0.6 was released in mid-july; blog post

Deployment

  • kustomize replaced ksonnet for application configuration
  • kfctl can now take a single YAML file specifying a KFDef describing Kubeflow (example)
  • ISTIO used as the service mesh

Metadata

  • Introduced support for artifact tracking via a UI and python SDK
  • Predefined schemas for models, datasets, and evaluation metrics

Multi-user support

  • ISTIO and RBAC for AuthZ
  • Dex provides a reference implementation for AuthN
  • Integration with GCP and AWS AuthN services
  • Profile resource to manage per-team namespaces
  • Kubeflow identity management API to manage multiple users/teams

Training

  • TFJob and PyTorch to 1.0

Pipelines

  • UI improvements:
    • 10x Perf improvement (e.g. load list of runs)
  • API performance optimization
  • streamlined run creation
  • stackdriver integration for logs (better debugging)
  • better visualization of metadata outputs
  • Tensorboard CRD
  • versioning for data volumes

Kubeflow 0.7

Following Kubeflow's quarterly relese schedule Kubeflow 0.7 will be released in October 2019.

Notebooks

  • Notebook infrastructure to beta quality in 0.7
    • 1.0 in the following release
  • The notebook infrastructure has 2 primary pieces; the jupyter notebook controller and web application for managing notebooks
  • Kanban board

Deployment

  • kfctl to beta quality in 0.7
    • 1.0 in the following release
  • v1beta1 for KfDef
    • Create a more consistent and clean API for describing Kubeflow deployments
    • Handle plugins and platforms consistently
  • Clean up kfctl flags and semantics
  • Upgradability between minor and major releases (issue)
  • Kanban board

Monitoring

  • Kubernetes' applications provide a unified view of the deployed Kubeflow applications and their state

Metadata

  • Generic logger to auto log K8s resources to metadata store
  • Kanban board

Pipelines

  • Local execution of pipelines for easy development
  • Enhanced metadata integration

Enterprise support

  • Restrict kubeflow access to subset of namespaces (kubeflow/kubeflow#3623)
  • Profile controller to beta
  • Kubeflow identity management API and UI to beta

Onpremise support

  • E2E CI for setup and multi-user support in on premise environments
  • Kanban board

Data management

  • Persistent volume management via a central dashboard UI

Engprod

  • Remove ksonnet from E2E testing
  • CI for applications in scope for 1.0 (notebooks, job operators, central dashboard etc..)
  • Kanban board

Support for hardware accelerated training and inference

  • Automatic injection of device configuration needed to use hardware accelerators for training and inference

Kubeflow 1.0

We are targeting a 1.0 release in January 2020. Our 1.0 release consists of the following key pieces

  1. A core set of applications targeting the critical user journey of build-train-deploy
  2. Scaffolding to securely deploy and manage multi-user Kubeflow environments on-prem and in the cloud.

We are currently targeting the following applications to graduate to 1.0 as part of the initial Kubeflow release

  • kfctl for deployment and upgrades
  • TFJob and PyTorch for distributed training (already 1.0)
  • Jupyter notebook controller and web app
  • Profile controller and UI for multiuser management

The following applications will likely be of beta quality for the 1.0 release with a goal of graduating to 1.0 in Q1 2020

  • Katib for hyper-parameter tuning
  • fairing SDK to facilite use of notebooks for build-train-deploy
  • Metadata SDK, UI, and backend
  • KFServing for model deployment and inference
  • Pipelines
    • CI/CD integration and Pipeline versioning are targeted for Q4 2019
    • Multi-tenancy and RBAC features are targeted for early Q1 2020

Here is a preliminary list of limitations and requirements that will be part of our 1.0 release

  • ISTIO will be required as a service mesh and for AuthN and AuthZ support

  • We will only support a single shared Kubeflow deployment per Kubernetes cluster

    • Users can consume Kubeflow in their own, isolated namespace
  • Upgrades will require downtime

  • Upgradability will not support advanced customization (e.g. custom overlays) for Kustomize packages

    • We expect application to expose a list of parameters that can be customized without breaking upgradability
    • Customization beyond these parameters will require manual configuration on upgrade
You can’t perform that action at this time.
