Quickstart: Set up the IoT Hub Device Provisioning Service with Azure CLI

The Azure CLI is used to create and manage Azure resources from the command line or in scripts. This quickstart details using the Azure CLI to create an IoT hub and an IoT Hub Device Provisioning Service instance, and to link the two services together.

If you don't have an Azure subscription, create an Azure free account before you begin.

Important

Both the IoT hub and the provisioning service you create in this quickstart will be publicly discoverable as DNS endpoints. Make sure to avoid any sensitive information if you decide to change the names used for these resources.

Prerequisites

Create a resource group

Create a resource group with the az group create command. An Azure resource group is a logical container into which Azure resources are deployed and managed.

The following example creates a resource group named my-sample-resource-group in the westus location.

az group create --name my-sample-resource-group --location westus

Tip

The example creates the resource group in the West US location. You can view a list of available locations by running the command az account list-locations -o table.

Create an IoT hub

Create an IoT hub with the az iot hub create command.

The following example creates an IoT hub named my-sample-hub in the westus location. An IoT hub name must be globally unique in Azure, so either add a unique prefix or suffix to the example name or choose a new name altogether. Make sure your name follows proper naming conventions for an IoT hub: it should be 3-50 characters in length, and can contain only upper or lower case alphanumeric characters or hyphens ('-').

az iot hub create --name my-sample-hub --resource-group my-sample-resource-group --location westus

Create a Device Provisioning Service instance

Create a Device Provisioning Service instance with the az iot dps create command.

The following example creates a Device Provisioning Service instance named my-sample-dps in the westus location. You must also choose a globally unique name for your own instance. Make sure it follows proper naming conventions for an IoT Hub Device Provisioning Service: it should be 3-64 characters in length and can contain only upper or lower case alphanumeric characters or hyphens ('-').

az iot dps create --name my-sample-dps --resource-group my-sample-resource-group --location westus

Tip

The example creates the provisioning service in the West US location. You can view a list of available locations by running the command az provider show --namespace Microsoft.Devices --query "resourceTypes[?resourceType=='ProvisioningServices'].locations | [0]" --out table or by going to the Azure Status page and searching for "Device Provisioning Service". In commands, locations can be specified either in one word or multi-word format; for example: westus, West US, WEST US, etc. The value is not case sensitive. If you use multi-word format to specify location, enclose the value in quotes; for example, --location "West US".

For resiliency and reliability, we recommend deploying to one of the regions that support Availability Zones.

Get the connection string for the IoT hub

You need your IoT hub's connection string to link it with the Device Provisioning Service. Use the az iot hub show-connection-string command to get the connection string and use its output to set a variable that's used later, when you link the two resources.

The following example sets the hubConnectionString variable to the value of the connection string for the primary key of the hub's iothubowner policy (the --policy-name parameter can be used to specify a different policy). Trade out my-sample-hub for the unique IoT hub name you chose earlier. The command uses the Azure CLI query and output options to extract the connection string from the command output.

hubConnectionString=$(az iot hub show-connection-string --name my-sample-hub --key primary --query connectionString -o tsv)

You can use the echo command to see the connection string.

echo $hubConnectionString

Note

These two commands are valid for a host running under Bash.

If you're using a local Windows/CMD shell or a PowerShell host, modify the commands to use the correct syntax for that environment.

If you're using Azure Cloud Shell, check that the environment drop-down on the left side of the shell window says Bash.

Link the IoT hub and your provisioning service with the az iot dps linked-hub create command.

The following example links an IoT hub named my-sample-hub in the westus location and a Device Provisioning Service named my-sample-dps. Trade out these names for the unique IoT hub and Device Provisioning Service names you chose earlier. The command uses the connection string for your IoT hub that was stored in the hubConnectionString variable in the previous step.

az iot dps linked-hub create --dps-name my-sample-dps --resource-group my-sample-resource-group --connection-string $hubConnectionString --location westus

The command may take a few minutes to complete.

Verify the provisioning service

Get the details of your provisioning service with the az iot dps show command.

The following example gets the details of a provisioning service named my-sample-dps. Trade out this name for your own Device Provisioning Service name.

az iot dps show --name my-sample-dps

The linked IoT hub is shown in the properties.iotHubs collection.

Verify Provisioning Service

Clean up resources

Other quickstarts in this collection build upon this quickstart. If you plan to continue on to work with subsequent quickstarts or with the tutorials, don't clean up the resources created in this quickstart. If you don't plan to continue, you can use the following commands to delete the provisioning service, the IoT hub or the resource group and all of its resources. Replace the names of the resources included in the following commands with the names of your own resources.

To delete the provisioning service, run the az iot dps delete command:

az iot dps delete --name my-sample-dps --resource-group my-sample-resource-group

To delete the IoT hub, run the az iot hub delete command:

az iot hub delete --name my-sample-hub --resource-group my-sample-resource-group

To delete a resource group and all its resources, run the az group delete command:

az group delete --name my-sample-resource-group

Next steps

In this quickstart, you deployed an IoT hub and a Device Provisioning Service instance, and linked the two resources. To learn how to use this setup to provision a device, continue to the quickstart for creating a device.
