Lab Objectives

By the end of this lab, you will:

• Understand how Azure Container Instances (ACI) works
• Create and deploy a containerized application using ACI
• Access and test the deployed container application

---

Pre-requisites

• An active Azure subscription
• Azure CLI installed locally
• Docker installed (optional, if building your own image)

---

Lab Steps

Step 1: Log in to Azure

bashCopyaz login

Step 2: Create a Resource Group

bashCopyaz group create --name myContainerRG --location eastus

Step 3: Deploy a Public Container Image

Let’s use the official mcr.microsoft.com/azuredocs/aci-helloworld image.

bashCopyaz container create \
  --resource-group myContainerRG \
  --name mycontainerapp \
  --image mcr.microsoft.com/azuredocs/aci-helloworld \
  --cpu 1 --memory 1 \
  --dns-name-label mycontainerappdemo123 \
  --ports 80

🔹 Make sure the --dns-name-label is unique across Azure.

Step 4: Check the Container Status

bashCopyaz container show --resource-group myContainerRG --name mycontainerapp --query "{FQDN:ipAddress.fqdn, ProvisioningState:provisioningState}" --out table

Step 5: Access the Application

Visit the URL output in the FQDN field from the previous step, such as:

arduinoCopyhttp://mycontainerappdemo123.eastus.azurecontainer.io

You should see a simple web page with the message “Welcome to Azure Container Instances!”

---

Bonus: Deploy a Custom Docker Image from Docker Hub

If you have a custom image on Docker Hub:

bashCopyaz container create \
  --resource-group myContainerRG \
  --name customcontainerapp \
  --image <yourdockerhubusername>/<imagename>:<tag> \
  --dns-name-label customcontainerdemo123 \
  --ports 80

Replace <yourdockerhubusername>/<imagename>:<tag> with your actual image details.

---

Clean Up Resources

bashCopyaz group delete --name myContainerRG --yes --no-wait

---

Conclusion

You have successfully deployed a containerized application using Azure Container Instances. This is a fast and cost-effective way to run containers without managing VMs or orchestration platforms.
