Create a SignalR Service

This sample script creates a new Azure SignalR Service resource in a new resource group with a random name.

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.

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

# Create a SignalR Service

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-azure-signalr-rg-$randomIdentifier"
tag="create-signal-service-and-group"
signalRSvc=msdocs-signalr-svc-$randomIdentifier
signalRSku="Standard_S1"
unitCount="1"
serviceMode="Default"

# Create a resource group
echo "Creating $resourceGroup in "$location"..."
az group create --name $resourceGroup --location "$location" --tag $tag

# Create the Azure SignalR Service resource
echo "Creating $signalRSvc"
az signalr create \
  --name $signalRSvc \
  --resource-group $resourceGroup \
  --sku $signalRSku \
  --unit-count $unitCount \
  --service-mode $serviceMode

# Get the SignalR primary connection string 
primaryConnectionString=$(az signalr key list --name $signalRSvc \
  --resource-group $resourceGroup --query primaryConnectionString -o tsv)

echo "$primaryConnectionString"

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

Each command in the table links to command specific documentation. This script uses the following commands:

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az signalr create	Creates an Azure SignalR Service resource.
az signalr key list	List the keys, which will be used by your application when pushing real-time content updates with SignalR.
