Lab 09c: Implement Azure Container Apps

Objective: This lab guides you through deploying a simple containerized application to Azure Container Apps (ACA).

Scenario: Your organization is migrating an on-premises web application to the cloud and wants to minimize server management. You'll evaluate Azure Container Apps as a serverless container solution.

Key Concepts:

• Azure Container Apps (ACA): A fully managed, serverless container platform built on Kubernetes. It allows you to run containerized applications without managing the underlying infrastructure (VMs or Kubernetes clusters directly).

• Container App Environment: A secure boundary around a group of container apps. All container apps within an environment share the same virtual network and write logs to the same Log Analytics workspace.

• Container App: A single application deployed to ACA, which can consist of one or more revisions. Each revision is an immutable snapshot of the app's configuration.

• Revision: A version of your container app's configuration. Changes to the container image, environment variables, or scaling rules create a new revision.

• Ingress: Controls how external traffic reaches your container app. ACA automatically configures HTTP ingress for you.

Job skills

• Task 1: Create and configure an Azure Container App and environment.

• Task 2: Test and verify deployment of the Azure Container App.

Task 1: Create and Configure an Azure Container App and Environment

• Sign In: Log in to the Azure portal (https://portal.azure.com).

• Create Container App: Search for and select "Container Apps" and click "Create."

  • Basics tab:

    • Container app name: my-app (or a unique name)

    • Container Apps Environment: Click "Create new."

      • Environment name: my-environment

      • Click "Create".

  • Container tab:

    • Ensure "Use quickstart image" is enabled.

    • The quick start image should be set to "Simple hello world container".

• Review + create: Verify the settings, and click "Create."

Task 2: Test and Verify Deployment

1. Go to Resource: Once deployed, click "Go to resource."

2. Access the Application:

   • On the "Overview" blade, find the "Application URL." This is the public endpoint for your container app.

   • Click the "Application URL" link. A new browser tab will open.

3. Verify Application: You should see a page with the message "Your Azure Container Apps app is live!". This confirms that your container app is running and accessible.

Cleanup (Crucial):

• Delete the az104-rg9 resource group (or the resource group you used) to remove all lab resources. This prevents unnecessary charges.
