Quickstart: Create an event hub using Azure CLI

Azure Event Hubs is a Big Data streaming platform and event ingestion service, capable of receiving and processing millions of events per second. Event Hubs can process and store events, data, or telemetry produced by distributed software and devices. Data sent to an event hub can be transformed and stored using any real-time analytics provider or batching/storage adapters. For detailed overview of Event Hubs, see Event Hubs overview and Event Hubs features.

In this quickstart, you create an event hub using Azure CLI.


To complete this quickstart, you need an Azure subscription. If you don't have one, create a free account before you begin.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article without having to install anything on your local environment.

To start Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com, or select the Launch Cloud Shell button to open Cloud Shell in your browser. Launch Cloud Shell in a new window
Select the Cloud Shell button on the menu bar at the upper right in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Start Cloud Shell.

  2. Select the Copy button on a code block to copy the code.

  3. Paste the code into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux or by selecting Cmd+Shift+V on macOS.

  4. Select Enter to run the code.

If you choose to install and use Azure CLI locally, this tutorial requires that you are running Azure CLI version 2.0.4 or later. Run az --version to check your version. If you need to install or upgrade, see Install the Azure CLI.

Sign in to Azure

The following steps are not required if you're running commands in Cloud Shell. If you're running the CLI locally, perform the following steps to sign in to Azure and set your current subscription:

Run the following command to sign in to Azure:

az login

Set the current subscription context. Replace MyAzureSub with the name of the Azure subscription you want to use:

az account set --subscription MyAzureSub

Create a resource group

A resource group is a logical collection of Azure resources. All resources are deployed and managed in a resource group. Run the following command to create a resource group:

# Create a resource group. Specify a name for the resource group.
az group create --name <resource group name> --location eastus

Create an Event Hubs namespace

An Event Hubs namespace provides a unique scoping container, referenced by its fully qualified domain name, in which you create one or more event hubs. To create a namespace in your resource group, run the following command:

# Create an Event Hubs namespace. Specify a name for the Event Hubs namespace.
az eventhubs namespace create --name <Event Hubs namespace> --resource-group <resource group name> -l <region, for example: East US>

Create an event hub

Run the following command to create an event hub:

# Create an event hub. Specify a name for the event hub. 
az eventhubs eventhub create --name <event hub name> --resource-group <resource group name> --namespace-name <Event Hubs namespace>

Congratulations! You have used Azure CLI to create an Event Hubs namespace, and an event hub within that namespace.

Next steps

In this article, you created a resource group, an Event Hubs namespace, and an event hub. For step-by-step instructions to send events to (or) receive events from an event hub, see the Send and receive events tutorials:
