Bicep Deployment

This directory contains the Bicep template and a deployment script for provisioning Azure Database for PostgreSQL Flexible Server resources in LocalStack for Azure. Refer to the Azure Database for PostgreSQL Flexible Server guide for details about the sample application.

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 deploy.sh script creates the Azure Resource Group for all the Azure resources, while the main.bicep Bicep module creates the following Azure resources:

  1. Azure Database for PostgreSQL Flexible Server: Managed PostgreSQL database server with version 16.
  2. PostgreSQL Database: The sampledb database for the Notes application.
  3. Firewall Rule: Allows access from all IP addresses for development.

For more information, see Azure Database for PostgreSQL Flexible Server.

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:

export LOCALSTACK_AUTH_TOKEN=<your_auth_token>
IMAGE_NAME=localstack/localstack-azure-alpha localstack start

Navigate to the bicep folder:

cd samples/postgresql-flexible-server/python/bicep

Make the script executable:

chmod +x deploy.sh

Run the deployment script:

./deploy.sh

Validation

After deployment, you can use the validate.sh script to verify that all resources were created and configured correctly:

#!/bin/bash

# Variables
ENVIRONMENT=$(az account show --query environmentName --output tsv)

# 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
$AZ group show \
--name rg-pgflex-bicep \
--output table

# List resources
$AZ resource list \
--resource-group rg-pgflex-bicep \
--output table

# Check PostgreSQL Flexible Server
$AZ postgres flexible-server list \
--resource-group rg-pgflex-bicep \
--output table

Cleanup

To destroy all created resources:

# Delete resource group and all contained resources
azlocal group delete --name rg-pgflex-bicep --yes --no-wait

# Verify deletion
azlocal group list --output table

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