As part of Azure Machine Learning (AzureML) service capabilities, AzureML Kubernetes extends AzureML service capabilities seamlessly from Azure cloud setting to any infrastructure across on-premises, multicloud, and the edge. With a simple AzureML extension deployment, you can instantly onboard your teams of ML professionals with productivity tools for full ML lifecycle, and have access to both Azure managed compute and customer managed Kubernetes anywhere. Your teams of ML professionals are flexible to build, train, and deploy models wherever and whenever business requires so and get consistent ML experience across different infrastructures.
You can easily bring AzureML capabilities to your Kubernetes cluster from cloud or on-premises by deploying AzureML extension.
- For Azure Kubernetes Service (AKS) in Azure, deploy AzureML extension to the AKS directly. For more information, see Deploy and manage cluster extensions for Azure Kubernetes Service (AKS).
- For Kubernetes clusters on-premises or from other cloud providers, you can connect the cluster with Azure Arc, then deploy AzureML extension. For more information, see Azure Arc-enabled Kubernetes.
This repository is intended to serve as an information hub for customers and partners who are interested in Azure Machine Learning anywhere with Kubernetes. Use this repository for onboarding and testing instructions as well as an avenue to provide feedback, issues, enhancement requests and stay up to date as the product evolves.
AzureML Kubernetes is customer fully configured and managed compute for machine learning. It can be used as both training compute target and inference compute target. It provides the following benefits:
- Harness existing heterogeneous or homogeneous Kubernetes cluster, with CPUs or GPUs.
- Share the same Kubernetes cluster in multiple AzureML Workspaces across region.
- Use the same Kubernetes cluster for different machine learning purposes, including model training, batch scoring, and real-time inference.
- Secure network communication between the cluster and cloud via Azure Private Link and Private Endpoint.
- Isolate team projects and machine learning workloads with Kubernetes node selector and namespace.
- Target certain types of compute nodes and CPU/Memory/GPU resource allocation for training and inference workloads.
- Connect with custom data sources for machine learning workloads using Kubernetes PV and PVC.
- A Kubernetes cluster up and running - We recommend minimum of 4 vCPU cores and 8GB memory, around 2 vCPU cores and 3GB memory will be used by Azure Arc agent and AzureML extension components.
- Other than Azure Kubernetes Services (AKS) cluster in Azure, you must connect your Kubernetes cluster to Azure Arc. Please follow instructions in connect existing Kubernetes cluster to Azure Arc.
- if you have Azure RedHat OpenShift Service (ARO) cluster or OpenShift Container Patform (OCP) cluster, follow additional prerequisite step here before AzureML extension deployment.
- if you have AKS cluster in Azure, Azure Arc connection is not required.
- Cluster running behind an outbound proxy server or firewall needs additional network configurations. Fulfill the network requirements
- Install or upgrade Azure CLI to version >=2.16.0
- Install Azure CLI extension
k8s-extension(version>=1.2.2) by runningaz extension add --name k8s-extension
Getting started with AzureML anywhere is easy with following steps:
- Deploy AzureML extension
- Attach Kubernetes cluster to AzureML workspace and create a compute target
- Train image classification model with AzureML CLI v2
- Deploy a trained image classification model
- Troubleshooting guide
AzureML anywhere essentially brings a new compute target to Azure Machine Learning service. With this new Kubernetes compute target, you can use existing AzureML tools and service capabilities to build, train, and deploy model on Kubernetes cluster anywhere. This seamless integration supports many AzureML built-in features , and existing AzureML examples can run on Kubernetes cluster with a smple change of compute target name.
In addition to many built-in AzureML features support, AzureML anywhere also supports following unique features leveraging native Kubernetes capability:
- Run training or inference workload with custom instance types for resource efficiency
- Train model with PV/PVC storage mount
- Assign managed identity to the compute
- Use managed identity for your endpoint
- Custom container registry support
- Multiple AzureML workspaces share the same Kubernetes cluster
- Deploy model using custom container with built-in model or entry script. In this case, the model and the entry scripts will stay on-premises localy and not uploaded to Azure cloud.

Kubernetes clusters installing AzureML extension have a version support window of "N-2", that is aligned with Azure Kubernetes Service (AKS) version support policy, where 'N' is the latest GA minor version of Azure Kubernetes Service.
For example, if AKS introduces 1.20.a today, versions 1.20.a, 1.20.b, 1.19.c, 1.19.d, 1.18.e, and 1.18.f are supported.
If customers are running an unsupported Kubernetes version, they will be asked to upgrade when requesting support for the cluster. Clusters running unsupported Kubernetes releases are not covered by the AzureML extension support policies.
All AzureML examples can be found in https://github.com/Azure/azureml-examples.git.
For any AzureML example, you only need to update the compute target name to your own Kubernetes compute target, then you are all done.
