How to Deploy a Web App Using Docker & Docker Hub on AWS EC2

How to Deploy a Web App Using Docker & Docker Hub on AWS EC2 | Step-by-Step Guide

**Description:**
Want to deploy your web application using Docker and host it on a cloud server? In this comprehensive tutorial, you’ll learn **how to deploy a web app on an AWS EC2 instance using Docker and Docker Hub**. Whether you're running a frontend app, backend server, or full-stack project — this guide walks you through every step of deploying containerized apps in the cloud.

Docker simplifies application deployment by packaging everything your app needs into a single container. When paired with Docker Hub (for storing and sharing images) and AWS EC2 (for hosting), you get a reliable and scalable setup.

✅ In this video, you’ll learn:

* How to set up an EC2 virtual machine on AWS
* How to install Docker on your EC2 instance
* How to pull your Docker image from Docker Hub
* How to run containers to serve your web application
* How to expose your app to the internet via open ports
* Tips on using custom domains and persistent storage

🛠 Prerequisites:

* Docker image pushed to [hub.docker.com](https://hub.docker.com)
* AWS account with EC2 access
* Basic knowledge of Docker and terminal commands

🚀 Steps Covered:

1. **Launch EC2 Instance**

* Use Ubuntu or Amazon Linux
* Open ports 22 (SSH) and 80/443 (HTTP/HTTPS) in security groups

2. **Connect to Your Instance**

* Use SSH or a terminal like PuTTY or Git Bash

3. **Install Docker on EC2**

```bash
sudo apt update
sudo apt install docker.io -y
sudo systemctl start docker
sudo systemctl enable docker
```

4. **Login to Docker & Pull Your Image**

```bash
sudo docker login
sudo docker pull yourdockerhubusername/yourimage:tag
```

5. **Run Your Container**

```bash
sudo docker run -d -p 80:80 yourdockerhubusername/yourimage:tag
```

6. **Access Your Web App**

* Use the EC2 instance’s public IP in any browser
* Ensure your app listens on the right port inside the container

💡 Bonus Tips:

* Use **Docker Compose** for multi-container apps
* Secure with **Nginx and Let’s Encrypt SSL**
* Add **Elastic IP** to keep your server address fixed
* Use **GitHub Actions** to automate Docker builds and pushes

🧑‍💻 Perfect For:

* Developers deploying full-stack or microservice apps
* Students learning DevOps, Docker, and AWS
* Anyone containerizing apps and hosting in the cloud
