Azure CLI Deployment

This directory contains Azure CLI scripts and a deployment script for provisioning Azure services in LocalStack for Azure. For further details about the sample application, refer to the Azure Service Bus with Spring Boot.

Prerequisites

Before deploying this solution, ensure you have the following tools installed:

Installing azlocal CLI

The deploy.sh Bash script uses the azlocal CLI instead of the standard Azure CLI to work with LocalStack. Install it using:

pip install azlocal

For more information, see Get started with the az tool on LocalStack.

Architecture Overview

The Azure CLI scripts create the following Azure resources:

  1. Azure Resource Group: A logical container scoping all resources in this sample.
  2. Azure Service Bus Namespace: The messaging namespace that hosts the queue used by the application.
  3. Azure Service Bus Queue: The myqueue queue used to send and receive messages.

The Spring Boot sample application connects to the Service Bus namespace, sends a test message to the sample queue, receives it back, and exits. For more information on the sample application, see Azure Service Bus with Spring Boot.

Provisioning Scripts

You can use the deploy.sh script to automate the deployment of all Azure resources and the sample application in a single step, streamlining setup and reducing manual configuration. The script executes the following steps:

  • Detects the environment (LocalStack vs Azure Cloud) and selects the appropriate CLI.
  • Checks whether each resource (resource group, namespace, queue) already exists before creating it.
  • Creates the Azure Resource Group in the specified location.
  • Creates the Service Bus Namespace within the resource group.
  • Creates the Service Bus Queue within the namespace.
  • Retrieves the connection string for the Service Bus namespace.
  • Compiles the Spring Boot project and runs the app on the host machine.

Deployment

You can set up the Azure emulator by utilizing LocalStack for Azure Docker image. Before starting, ensure you have a valid LOCALSTACK_AUTH_TOKEN to access the Azure emulator. Refer to the Auth Token guide to obtain your Auth Token and specify it in the LOCALSTACK_AUTH_TOKEN environment variable. The Azure Docker image is available on the LocalStack Docker Hub. To pull the Azure Docker image, execute the following command:

docker pull localstack/localstack-azure-alpha

Start the LocalStack Azure emulator using the localstack CLI, execute the following command:

# Set the authentication token
export LOCALSTACK_AUTH_TOKEN=<your_auth_token>

# Start the LocalStack Azure emulator
IMAGE_NAME=localstack/localstack-azure-alpha localstack start -d
localstack wait -t 60

# Route all Azure CLI calls to the LocalStack Azure emulator
azlocal start-interception

Navigate to the scripts folder:

cd samples/servicebus/java/scripts

Make the script executable:

chmod +x deploy.sh

Run the deployment script:

./deploy.sh

Validation

Once the deployment completes, run the validate.sh script to confirm that all resources were provisioned and configured as expected:

#!/bin/bash

# Variables
PREFIX='local'
SUFFIX='test'
RESOURCE_GROUP_NAME="${PREFIX}-rg"
SERVICEBUS_NAMESPACE_NAME="${PREFIX}-sb-ns-${SUFFIX}"
SERVICEBUS_QUEUE_NAME="myqueue"

# Choose the appropriate CLI based on the environment
if [[ $ENVIRONMENT == "LocalStack" ]]; then
  echo "Using azlocal for LocalStack emulator environment."
  AZ="azlocal"
else
  echo "Using standard az for AzureCloud environment."
  AZ="az"
fi

# Check resource group
echo -e "[$RESOURCE_GROUP_NAME] resource group:\n"
az group show \
  --name "$RESOURCE_GROUP_NAME" \
  --output table \
  --only-show-errors

# Check Service Bus namespace
echo -e "\n[$SERVICEBUS_NAMESPACE_NAME] Service Bus namespace:\n"
az servicebus namespace show \
  --resource-group "$RESOURCE_GROUP_NAME" \
  --name "$SERVICEBUS_NAMESPACE_NAME" \
	--query "{name:name, location:location, serviceBusEndpoint:serviceBusEndpoint, status:provisioningState}" \
  --output table \
  --only-show-errors

# Check Service Bus queue
echo -e "\n[$SERVICEBUS_QUEUE_NAME] Service Bus queue:\n"
az servicebus queue show \
  --resource-group "$RESOURCE_GROUP_NAME" \
  --namespace-name "$SERVICEBUS_NAMESPACE_NAME" \
  --name "$SERVICEBUS_QUEUE_NAME" \
	--query "{name:name, messageCount:messageCount, sizeInBytes:sizeInBytes}" \
  --output table \
  --only-show-errors

Cleanup

To destroy all created resources:

#!/bin/bash

# Variables
PREFIX='local'
SUFFIX='test'
RESOURCE_GROUP_NAME="${PREFIX}-rg"

# Delete resource group and all contained resources
az group delete --name $RESOURCE_GROUP_NAME --yes --no-wait

# Verify deletion
az group list --output table

This will remove all Azure resources created by the CLI deployment script.
