Using CLI to create Azure Bus Service

Service Bus queues are a general-purpose technology that can be used for a wide variety of scenarios:

• Communication between web and worker roles in a multi-tier Azure application.
• Communication between on-premises apps and Azure-hosted apps in a hybrid solution.
• Communication between components of a distributed application running on-premises in different organizations or departments of an organization.

In Cloud Shell, from the Bash prompt issue the following commands to provision Service Bus resources. Be sure to replace all placeholders with the appropriate values: The Java sample program expects the queue name to be BasicQueue, so do not change it. 

1. Create a resource group

resourceGroupName="myResourceGroup"

az group create --name $resourceGroupName --location eastus

2. Create a Service Bus messaging namespace with a unique name

namespaceName=myNameSpace$RANDOM

az servicebus namespace create --resource-group $resourceGroupName --name $namespaceName --location eastus

3. Create a Service Bus queue

az servicebus queue create --resource-group $resourceGroupName --namespace-name $namespaceName --name BasicQueue

4. Get the connection string for the namespace

connectionString=$(az servicebus namespace authorization-rule keys list --resource-group $resourceGroupName --namespace-name $namespaceName --name RootManageSharedAccessKey --query primaryConnectionString --output tsv)
