Deploy a model to Azure Container Instances with CLI (v1)

Learn how to use Azure Machine Learning to deploy a model as a web service on Azure Container Instances (ACI). Use Azure Container Instances if you:

• prefer not to manage your own Kubernetes cluster
• are okay with having only a single replica of your service, which might affect uptime

For information on quota and region availability for ACI, see the Quotas and region availability for Azure Container Instances article.

Prerequisites

• An Azure Machine Learning workspace. For more information, see Create an Azure Machine Learning workspace.

• A machine learning model registered in your workspace. If you don't have a registered model, see How and where to deploy models.

• The Azure CLI extension (v1) for Machine Learning service, Azure Machine Learning Python SDK, or the Azure Machine Learning Visual Studio Code extension.

• The Python code snippets in this article assume that the following variables are set:

  • ws - Set to your workspace.
  • model - Set to your registered model.
  • inference_config - Set to the inference configuration for the model.

  For more information on setting these variables, see How and where to deploy models.

• The CLI snippets in this article assume that you created an inferenceconfig.json file. For more information on creating this file, see How and where to deploy models.

Limitations

Deploy to ACI

To deploy a model to Azure Container Instances, create a deployment configuration that describes the compute resources needed, such as the number of cores and memory. You also need an inference configuration, which describes the environment needed to host the model and web service. For more information on creating the inference configuration, see How and where to deploy models.

Using the SDK

APPLIES TO: Azure Machine Learning SDK v1 for Python

from azureml.core.webservice import AciWebservice, Webservice
from azureml.core.model import Model

deployment_config = AciWebservice.deploy_configuration(cpu_cores = 1, memory_gb = 1)
service = Model.deploy(ws, "aciservice", [model], inference_config, deployment_config)
service.wait_for_deployment(show_output = True)
print(service.state)

For more information on the classes, methods, and parameters used in this example, see the following reference articles:

• AciWebservice.deploy_configuration
• Model.deploy
• Webservice.wait_for_deployment

Using the Azure CLI

APPLIES TO: Azure CLI ml extension v1

To deploy by using the CLI, run the following command. Replace mymodel:1 with the name and version of the registered model. Replace myservice with the name to give this service:

az ml model deploy -n myservice -m mymodel:1 --ic inferenceconfig.json --dc deploymentconfig.json

The entries in the deploymentconfig.json file map to the parameters for AciWebservice.deploy_configuration. The following table describes the mapping between the entities in the JSON file and the parameters for the method:

The following JSON is an example deployment configuration for use with the CLI:

{
    "computeType": "aci",
    "containerResourceRequirements":
    {
        "cpu": 0.5,
        "memoryInGB": 1.0
    },
    "authEnabled": true,
    "sslEnabled": false,
    "appInsightsEnabled": false
}

For more information, see the az ml model deploy reference.
