Exercise - Deploy KEDA on an Azure Kubernetes Service cluster

  • 5 minutes

Enable the KEDA add-on on an AKS cluster

  1. Use the following commands to create environment variables for the resource group name, location, and cluster name for use throughout this module:

    RESOURCE_GROUP=<resource-group-name>
LOCATION=<location>
CLUSTER_NAME=<aks-cluster-name>

  2. Create an Azure resource group using the az group create command.

    az group create --name $RESOURCE_GROUP --location $LOCATION

  3. Create an AKS cluster with the KEDA add-on enabled using the az aks create command and the --enable-keda flag.

    az aks create --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --enable-keda --generate-ssh-keys

    This command can take a few minutes to run.

  4. Connect to your AKS cluster using the az aks get-credentials command.

    az aks get-credentials --name $CLUSTER_NAME --resource-group $RESOURCE_GROUP

  5. Verify the KEDA add-on is installed on your cluster using the az aks show command and set the --query flag to workloadAutoScalerProfile.keda.enabled.

    az aks show --name $CLUSTER_NAME --resource-group $RESOURCE_GROUP --query "workloadAutoScalerProfile.keda.enabled"

    Your output should look like the following example output, which shows the KEDA add-on is installed on the cluster:

    true

Create an Azure Cache for Redis instance

  1. Use the following command to create an environment variable for the Redis name for use throughout this module:

    REDIS_NAME=contoso-redis-$RANDOM

  2. Create an Azure Cache for Redis instance using the az redis create command:

    az redis create --location $LOCATION --name $REDIS_NAME --resource-group $RESOURCE_GROUP --sku Basic --vm-size c0 --enable-non-ssl-port

    This command can take several minutes to run.

  3. Create environment variables for the Redis host and key for use throughout this module using the az redis show and az redis list-keys commands:

    REDIS_HOST=$(az redis show -n $REDIS_NAME -g $RESOURCE_GROUP -o tsv --query "hostName")
REDIS_KEY=$(az redis list-keys --name $REDIS_NAME --resource-group $RESOURCE_GROUP -o tsv --query "primaryKey")
