Create a Premium Azure Cache for Redis with clustering

In this scenario, you learn how to create a 6 GB Premium tier Azure Cache for Redis with clustering enabled and two shards. You then learn to get details of an Azure Cache for Redis instance, including provisioning status, the hostname, ports, and keys for an Azure Cache for Redis instance. Finally, you learn to delete the cache.

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 subscriptionId with your Azure subscription ID.

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

subscription="subscriptionId" # Set Azure subscription ID 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 and manage a premium P1 Redis Cache with clustering

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="East US"
resourceGroup="msdocs-redis-cache-rg-$randomIdentifier"
tag="create-manage-premium-cache-cluster"
cache="msdocs-redis-cache-$randomIdentifier"
sku="premium"
size="P1"
shardCount="2"

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

# Create a Premium P1 (6 GB) Redis Cache with clustering enabled and 2 shards (for a total of 12 GB)
echo "Creating $cache"
az redis create --name $cache --resource-group $resourceGroup --location "$location" --sku $sku --vm-size $size --shard-count $shardCount

# Get details of an Azure Cache for Redis
echo "Showing details of $cache"
az redis show --name $cache --resource-group $resourceGroup 

# Retrieve the hostname and ports for an Azure Redis Cache instance
redis=($(az redis show --name $resourceGroup --resource-group $resourceGroup --query [hostName,enableNonSslPort,port,sslPort] --output tsv))

# Retrieve the keys for an Azure Redis Cache instance
keys=($(az redis list-keys --name contosoCache --resource-group contosoGroup --query [primaryKey,secondaryKey] --output tsv))

# Display the retrieved hostname, keys, and ports
echo "Hostname:" ${redis[0]}
echo "Non SSL Port:" ${redis[2]}
echo "Non SSL Port Enabled:" ${redis[1]}
echo "SSL Port:" ${redis[3]}
echo "Primary Key:" ${keys[0]}
echo "Secondary Key:" ${keys[1]}

# Delete a redis cache
echo "Deleting $cache"
az redis delete --name $resourceGroup --resource-group $resourceGroup -y

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

This script uses the following commands to create a resource group and a Premium tier Azure Cache for Redis with clustering enable. Each command in the table links to command specific documentation.

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az redis create	Create Azure Cache for Redis instance.
az redis show	Retrieve details of an Azure Cache for Redis instance.
az redis list-keys	Retrieve access keys for an Azure Cache for Redis instance.
az redis delete	Delete Azure Cache for Redis instance.
