Dapr integration overview in Azure - Mini Project: Build & Apply

Dapr Integration Overview on Azure

📖 Scenario: You are working on a cloud project where you want to use Dapr to simplify building microservices on Azure. Dapr helps your services communicate easily and securely.In this project, you will create a simple Azure resource setup that includes a container app with Dapr enabled.

🎯 Goal: Build an Azure Container App resource configuration that enables Dapr integration with a specified app ID and port.

📋 What You'll Learn

Create an Azure Container App resource with a specific name

Enable Dapr integration with a given app ID

Set the Dapr HTTP port to 3500

Configure the container app to listen on port 80

💡 Why This Matters

🌍 Real World

Dapr simplifies building microservices by handling service-to-service communication, state management, and more. Azure Container Apps is a managed service to run containers with Dapr support.

💼 Career

Understanding how to configure Dapr on Azure Container Apps is useful for cloud developers and architects working on scalable microservices.

1

Create the Azure Container App resource dictionary

Create a dictionary called container_app with keys name set to "myapp" and containers as a list containing one dictionary with name set to "mycontainer" and image set to "myimage:v1".

Need a hint?

Think of this as creating a box named 'myapp' that holds one smaller box named 'mycontainer' with an image inside.

2

Add Dapr configuration to the container app

Add a key dapr to the container_app dictionary. Set it to a dictionary with enabled as true, app_id as "mydaprapp", and http_port as 3500.

Azure

container_app = {
    "name": "myapp",
    "containers": [
        {
            "name": "mycontainer",
            "image": "myimage:v1"
        }
    ]
}
# Your code here

Need a hint?

Think of this as turning on Dapr for your app and giving it a name and port to listen on.

3

Add port configuration to the container

Inside the first container dictionary in container_app["containers"], add a key ports with a list containing the integer 80.

Azure

container_app = {
    "name": "myapp",
    "containers": [
        {
            "name": "mycontainer",
            "image": "myimage:v1"
        }
    ],
    "dapr": {
        "enabled": true,
        "app_id": "mydaprapp",
        "http_port": 3500
    }
}
# Your code here

This tells your container to listen on port 80, like opening a door for web traffic.

4

Complete the Azure Container App configuration dictionary

Add a key configuration to container_app with a dictionary containing ingress set to a dictionary with external as true and target_port as 80.

Azure

container_app = {
    "name": "myapp",
    "containers": [
        {
            "name": "mycontainer",
            "image": "myimage:v1",
            "ports": [80]
        }
    ],
    "dapr": {
        "enabled": true,
        "app_id": "mydaprapp",
        "http_port": 3500
    }
}
# Your code here

This final step opens your app to the internet on port 80, so users can reach it.
