# Lab 09b - Implement Azure Container Instances
# Lab 09b - Implement Azure Container Apps
## Lab introduction
In this lab, you learn how to implement Azure Container Instances and Azure Container Apps. You learn to deploy an Azure Container Instance to display a Hello World app.
You learn to deploy the default Azure Container App.
In this lab, you learn how to implement and deploy Azure Container Apps.
This lab requires an Azure subscription. Your subscription type may affect the availability of features in this lab. You may change the region, but the steps are written using **East US**.

## Interactive lab simulations
There are interactive lab simulations that you might find useful for this topic. The simulation lets you to click through a similar scenario at your own pace. There are differences between the interactive simulation and this lab, but many of the core concepts are the same. An Azure subscription is not required.

## Task 1: Deploy an Azure Container Instance using a Docker image
In this task, you will create a new container instance for the web application. Docker is a platform that provides the ability to package and run applications in isolated environments called containers. Azure Container Instances provides the compute environment for a container image.
1. Sign in to the **Azure portal** - `https://portal.azure.com`.
1. In the Azure portal, search for and select `Container instances` and then, on the **Container instances** blade, click **+ Create**.
1. On the **Basics** tab of the **Create container instance** blade, specify the following settings (leave others with their default values):
| Setting | Value |
| ---- | ---- |
| Subscription | Select your Azure subscription |
| Resource group | `az104-rg9` (If necessary, select **Create new**) |
| Container name | `az104-c1` |
| Region | **East US** (or a region available near you)|
| Image Source | **Quickstart images** |
| Image | **mcr.microsoft.com/azuredocs/aci-helloworld:latest (Linux)** |
1. Click **Next: Networking >** and specify the following settings (leave others with their default values):
| Setting | Value |
| --- | --- |
| DNS name label | any valid, globally unique DNS host name |
>**Note**: Your container will be publicly reachable at dns-name-label.region.azurecontainer.io. If you receive a **DNS name label not available** error message, specify a different value.
1. Click **Next: Advanced >**, review the settings without making any changes.
1. Click **Review + Create**, ensure that the validation passed and then select **Create**.
>**Note**: Wait for the deployment to complete. This should take 2-3 minutes.
>**Note**: While you wait, you may be interested in viewing the [code behind the sample application](https://github.com/Azure-Samples/aci-helloworld). To view the code, browse the \\app folder.
## Task 2: Review the functionality of the Azure Container Instance
In this task, you will review the deployment of the container instance. By default, the Azure Container Instance will be accessible over port 80. After the instance has been deployed, you can navigate to the container using the DNS name that you provided in the previous task.
1. On the deployment blade, click the **Go to resource** link.
1. On the **Overview** blade of the container instance, verify that **Status** is reported as **Running**.
1. Copy the value of the container instance **FQDN**, open a new browser tab, and navigate to the corresponding URL.
![Screenshot of the ACI overview page in the portal.](../media/az104-lab09b-aci-overview.png)
1. Verify that the **Welcome to Azure Container Instance** page is displayed. Refresh the page several times to create some log entries then close the browser tab.
1. In the **Settings** section of the container instance blade, click **Containers**, and then click **Logs**.
1. Verify that you see the log entries representing the HTTP GET request generated by displaying the application in the browser.

## Task 1: Create a container app and environment
Azure Container Apps take the concept of a managed Kubernetes cluster a step further and manages the cluster environment as well as provides other managed services on top of the cluster. Unlike an Azure Kubernetes cluster, where you must still manage the cluster, an Azure Container Apps instance removes some of the complexity to setting up a Kubernetes cluster.

Congratulations on completing the lab. Here are the main takeaways for this lab.
+ Azure Container Instances (ACI) is a service that enables you to deploy containers on the Microsoft Azure public cloud. ACI doesn't require you to provision or manage any underlying infrastructure. The service supports both Linux containers and Windows containers.
+ Azure Container Apps (ACA) is a serverless platform that allows you to maintain less infrastructure and save costs while running containerized applications. Instead of worrying about server configuration, container orchestration, and deployment details, Container Apps provides all the up-to-date server resources required to keep your applications stable and secure.
+ Workloads on ACI are usually started and stopped by some kind of process or trigger and are usually short-lived. Workloads on ACA are usually long-running processes like a Web App.

## Learn more with self-paced training
+ [Run container images in Azure Container Instances](https://learn.microsoft.com/training/modules/create-run-container-images-azure-container-instances/). Learn how Azure Container Instances can help you quickly deploy containers, how to set environment variables, and specify container restart policies.
+ [Configure a container app in Azure Container Apps](https://learn.microsoft.com/training/modules/configure-container-app-azure-container-apps/). Examines the features and capabilities of Azure Container Apps, and then focuses on how to create, configure, scale, and manage container apps using Azure Container Apps.
## Cleanup your resources
If you are working with your own subscription take a minute to delete the lab resources. This will ensure resources are freed up and cost is minimized. The easiest way to delete the lab resources is to delete the lab resource group.
