Deploying Docker Containers in Azure – A Beginner’s Guide

Blog Article

Containerization is now a core part of modern application development, and Docker is at the center of it all. If you’re looking to deploy Docker containers in Azure, the good news is that Microsoft Azure offers several services to make it simple, fast, and scalable — even for beginners.

In this guide, we’ll walk you through what containers are, how Azure supports them, and the step-by-step process to deploy a Docker container on Azure.

???? What is a Docker Container?

A Docker container is a lightweight, portable package that includes everything your application needs to run — code, libraries, dependencies, and runtime. Unlike virtual machines, containers share the host OS and are much faster to start and manage.

???? Azure Services for Running Docker Containers

Azure gives you multiple options to run Docker containers:

  1. Azure Container Instances (ACI) – Easiest way to run containers without managing servers.

  2. Azure Kubernetes Service (AKS) – For running and orchestrating multiple containers at scale.

  3. App Service for Containers – Deploy web apps and APIs in Docker containers.

  4. Azure Virtual Machines – Manually install Docker and run containers, useful for custom setups.

For simplicity, we’ll focus on using Azure Container Instances in this tutorial.

✅ Prerequisites

Before we begin:

  • You need a Microsoft Azure account (Create one for free)

  • You need a Docker image (either custom or from Docker Hub)

???? Step-by-Step: Deploying a Docker Container with Azure Container Instances

Step 1: Log in to Azure Portal

Visit https://portal.azure.com and sign in.

Step 2: Create a Container Instance

  1. Click Create a resource

  2. Search for Container Instances

  3. Click Create

Basic Setup:

  • Subscription: Choose your Azure subscription

  • Resource Group: Create new or use an existing one

  • Container name: Name your container instance

  • Region: Choose the closest data center

  • Image source: Select Docker Hub or a private registry

  • Image type: Enter your image name (e.g., nginx, yourusername/myapp)

  • OS type: Linux or Windows (depending on your container)

  • Size: Choose CPU and memory requirements

Click Review + Create, then Create

Step 3: Access Your Container

Once deployed, you can access your container using the DNS name provided (e.g., myapp.eastus.azurecontainer.io).

Go to your container resource, and you’ll find the FQDN or public IP under the Overview tab.

⚙️ Optional: Deploy with Azure CLI

If you prefer command line, here’s how to deploy a container:

bash
az container create --resource-group myResourceGroup --name mycontainer --image nginx --dns-name-label mynginxdemo --ports 80

???? Real-World Use Cases

  • Hosting microservices and APIs

  • Running scheduled jobs or tasks

  • Development and test environments

  • Temporary web servers or demos

For production-level workloads, consider Azure Kubernetes Service (AKS), which offers full orchestration, scaling, and networking for complex apps.
