Quickstart: Create a Web PubSub instance with the Azure CLI

The Azure CLI is a set of commands used to create and manage Azure resources. The Azure CLI is available across Azure services and is designed to get you working quickly with Azure, with an emphasis on automation. This quickstart shows you the options to create Azure Web PubSub instance with the Azure CLI.

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

Prerequisites

• Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.

  

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

• This quickstart requires version 2.22.0 or higher of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Create a resource group

A resource group is a logical container into which Azure resources are deployed and managed. Use the az group create command to create a resource group named myResourceGroup in the eastus location.

az group create --name myResourceGroup --location EastUS

Create a Web PubSub instance

Run az extension add to install or upgrade the webpubsub extension to the current version.

az extension add --upgrade --name webpubsub

Use the Azure CLI az webpubsub create command to create a Web PubSub in the resource group you've created. The following command creates a Free Web PubSub resource under resource group myResourceGroup in EastUS:

az webpubsub create --name "<your-unique-resource-name>" --resource-group "myResourceGroup" --location "EastUS" --sku Free_F1

The output of this command shows properties of the newly created resource. Take note of the two properties listed below:

• Resource Name: The name you provided to the --name parameter above.
• hostName: In the example, the host name is <your-unique-resource-name>.webpubsub.azure.com/.

At this point, your Azure account is the only one authorized to perform any operations on this new resource.

Try the newly created instance

Clean up resources

If you plan to continue on to work with subsequent quickstarts and tutorials, you may wish to leave these resources in place.

When no longer needed, you can use the Azure CLI az group delete command to remove the resource group and all related resources:

az group delete --name "myResourceGroup"

Next steps

In real-world applications, you can use SDKs in various languages build your own application. We also provide Function extensions for you to build serverless applications easily.
