Environment variables and configuration in Azure - Mini Project: Build & Apply

Environment variables and configuration

📖 Scenario: You are setting up a simple Azure App Service application. You need to manage environment variables to store configuration settings securely and access them in your app.

🎯 Goal: Build an Azure App Service configuration that defines environment variables and accesses them in the app settings.

📋 What You'll Learn

Create an Azure App Service resource configuration dictionary

Add environment variables as app settings

Use a configuration variable to hold environment variable names

Apply environment variables in the app service configuration

💡 Why This Matters

🌍 Real World

Managing environment variables securely is essential for cloud applications to separate code from configuration and protect sensitive data.

💼 Career

Cloud engineers and developers often configure environment variables in Azure App Services to manage app settings and secrets without hardcoding them.

1

Create Azure App Service configuration dictionary

Create a dictionary called app_service_config with these exact entries: 'name': 'myappservice', 'location': 'eastus', and 'resource_group': 'myResourceGroup'.

Azure

# Create the app_service_config dictionary with name, location, and resource_group
# Your code here

Need a hint?

Use a Python dictionary with keys 'name', 'location', and 'resource_group' and assign the exact string values.

2

Add environment variables as app settings

Add a key 'app_settings' to the app_service_config dictionary. Set its value to a dictionary with these exact environment variables: 'DATABASE_URL': 'mysql://user:pass@host/db' and 'API_KEY': '12345-abcde'.

Azure

app_service_config = {
    'name': 'myappservice',
    'location': 'eastus',
    'resource_group': 'myResourceGroup'
}
# Add 'app_settings' key with environment variables dictionary
# Your code here

Need a hint?

Add a nested dictionary under the key 'app_settings' with the exact environment variable names and values.

3

Create configuration variable for environment variable names

Create a list called env_vars containing the exact strings 'DATABASE_URL' and 'API_KEY'.

Azure

app_service_config = {
    'name': 'myappservice',
    'location': 'eastus',
    'resource_group': 'myResourceGroup',
    'app_settings': {
        'DATABASE_URL': 'mysql://user:pass@host/db',
        'API_KEY': '12345-abcde'
    }
}
# Create a list called env_vars with 'DATABASE_URL' and 'API_KEY'
# Your code here

Need a hint?

Use a Python list with the exact strings 'DATABASE_URL' and 'API_KEY'.

4

Apply environment variables in app service configuration

Add a new key 'environment_variables' to app_service_config. Set its value to a dictionary comprehension that includes keys and values from app_service_config['app_settings'] only for keys in the env_vars list.

Azure

app_service_config = {
    'name': 'myappservice',
    'location': 'eastus',
    'resource_group': 'myResourceGroup',
    'app_settings': {
        'DATABASE_URL': 'mysql://user:pass@host/db',
        'API_KEY': '12345-abcde'
    }
}
env_vars = ['DATABASE_URL', 'API_KEY']
# Add 'environment_variables' key with filtered app_settings using env_vars
# Your code here

Need a hint?

Use a dictionary comprehension to filter app_settings by keys in env_vars and assign it to 'environment_variables'.
