Application settings and connection strings in Azure - Mini Project: Build & Apply

Application settings and connection strings

📖 Scenario: You are setting up a web application in Azure. To make your app work correctly, you need to store some important information like application settings and connection strings securely. These settings tell your app how to connect to databases and other services.

🎯 Goal: Build an Azure App Service configuration with application settings and connection strings defined in a JSON format. This configuration will be used to deploy the app with the correct environment variables.

📋 What You'll Learn

Create a JSON object for app settings with exact keys and values

Add a connection strings section with a named connection string

Use correct Azure App Service configuration structure

Ensure the JSON is valid and deployable

💡 Why This Matters

🌍 Real World

Storing app settings and connection strings securely is essential for cloud apps to connect to databases and services without hardcoding sensitive info.

💼 Career

Cloud engineers and DevOps professionals often create and manage these configurations to ensure apps run correctly and securely in Azure.

1

Create the application settings section

Create a JSON object called appSettings with these exact key-value pairs: "ENVIRONMENT": "Production" and "LOG_LEVEL": "Warning".

Azure

{
  "appSettings": {
    // Your code here
  }
}

Need a hint?

Use a JSON object with keys and string values inside appSettings.

2

Add the connection strings section

Add a JSON object called connectionStrings with one entry named DefaultConnection having the value "Server=myserver;Database=mydb;User Id=myuser;Password=mypassword;".

Azure

{
  "appSettings": {
    "ENVIRONMENT": "Production",
    "LOG_LEVEL": "Warning"
  },
  "connectionStrings": {
    // Your code here
  }
}

Need a hint?

Place the connection string inside connectionStrings as a key-value pair.

3

Wrap settings in Azure App Service configuration format

Wrap the existing appSettings and connectionStrings inside a top-level JSON object with the key properties.

Azure

{
  "properties": {
    // Your code here
  }
}

Need a hint?

Put both appSettings and connectionStrings inside properties.

4

Add the slot setting flag to connection strings

Inside connectionStrings, add a nested object for DefaultConnection with keys value set to "Server=myserver;Database=mydb;User Id=myuser;Password=mypassword;" and slotSetting set to true.

Azure

{
  "properties": {
    "appSettings": {
      "ENVIRONMENT": "Production",
      "LOG_LEVEL": "Warning"
    },
    "connectionStrings": {
      // Your code here
    }
  }
}

Need a hint?

Use an object for DefaultConnection with value and slotSetting keys.
