Meta Description
Learn how to deploy a website using Docker with this step-by-step beginner’s guide. Discover how to containerize, build, and run websites using Docker in 2026.
How to Deploy a Website Using Docker Step-by-Step
Docker has completely changed the way developers deploy websites and applications. Instead of worrying about server configurations, dependencies, and compatibility issues, Docker allows you to package everything your website needs into a lightweight container that can run anywhere.
Whether you’re deploying a simple HTML website, a WordPress blog, or a modern web application, Docker makes deployment faster, more reliable, and easier to manage.
In this guide, you’ll learn how to deploy a website using Docker step by step, even if you’re a complete beginner.
What Is Docker?
Docker is an open-source platform that allows developers to package applications and their dependencies into containers.
A container includes:
- Application code
- Runtime environment
- Libraries
- Dependencies
- Configuration files
This ensures your website works the same way on:
- Local computer
- Development server
- Production server
- Cloud platforms
Why Use Docker for Website Deployment?
Benefits of Docker
| Feature | Benefit |
|---|---|
| Portability | Run anywhere |
| Fast Deployment | Deploy in minutes |
| Consistency | Eliminates “works on my machine” issues |
| Scalability | Easy to scale applications |
| Isolation | Applications run independently |
| Resource Efficient | Uses fewer resources than virtual machines |
Prerequisites
Before deploying your website with Docker, make sure you have:
- Basic command line knowledge
- A Linux, Windows, or Mac computer
- Docker installed
- A website project ready for deployment
Step 1: Install Docker
On Ubuntu
sudo apt update
sudo apt install docker.io
Start Docker:
sudo systemctl start docker
sudo systemctl enable docker
Check installation:
docker --version
Example output:
Docker version 28.x.x
On Windows or Mac
Download and install:
- Docker Desktop
After installation:
docker --version
Step 2: Create Your Website Files
Example project structure:
my-website/
│
├── index.html
├── style.css
├── app.js
└── Dockerfile
Example HTML file:
<!DOCTYPE html>
<html>
<head>
<title>My Docker Website</title>
</head>
<body>
<h1>Hello from Docker!</h1>
</body>
</html>
Step 3: Create a Dockerfile
A Dockerfile contains instructions for building your container.
Create a file named:
Dockerfile
Add the following code:
FROM nginx:latest
COPY . /usr/share/nginx/html
EXPOSE 80
Understanding the Dockerfile
| Command | Purpose |
|---|---|
| FROM | Selects base image |
| COPY | Copies website files |
| EXPOSE | Opens container port |
Step 4: Build the Docker Image
Navigate to your project folder:
cd my-website
Build the image:
docker build -t mywebsite .
Explanation:
docker build
Builds the image.
-t mywebsite
Names the image.
.
Uses the current directory.
Step 5: Verify the Image
List available images:
docker images
Example:
REPOSITORY TAG IMAGE ID
mywebsite latest a1b2c3d4
nginx latest x1y2z3
Step 6: Run the Docker Container
Start the container:
docker run -d -p 8080:80 mywebsite
Explanation:
| Option | Meaning |
|---|---|
| -d | Run in background |
| -p | Map ports |
| 8080 | Host machine port |
| 80 | Container port |
Step 7: Access Your Website
Open your browser:
http://localhost:8080
You should now see:
Hello from Docker!
Congratulations! Your website is running inside Docker.
Step 8: View Running Containers
docker ps
Example output:
CONTAINER ID IMAGE PORTS
123abc mywebsite 0.0.0.0:8080->80/tcp
Step 9: Stop the Container
docker stop container_id
Example:
docker stop 123abc
Step 10: Restart the Container
docker start container_id
Step 11: Remove a Container
docker rm container_id
Step 12: Remove an Image
docker rmi mywebsite
Deploying Docker on a VPS Server
You can deploy your Docker website on:
- Ubuntu VPS
- AWS EC2
- Google Cloud VM
- Azure Virtual Machine
- DigitalOcean Droplet
Typical deployment steps:
git clone your-project
cd project
docker build -t mywebsite .
docker run -d -p 80:80 mywebsite
Your website will become publicly accessible through:
http://your-server-ip
Using Docker Compose
For websites with databases and multiple services, Docker Compose is recommended.
Example:
version: '3'
services:
web:
build: .
ports:
- "80:80"
Start services:
docker compose up -d
Stop services:
docker compose down
Docker Deployment Architecture
| Component | Purpose |
|---|---|
| Docker Engine | Runs containers |
| Docker Image | Application template |
| Container | Running application |
| Dockerfile | Build instructions |
| Docker Compose | Multi-container management |
Best Practices for Docker Website Deployment
Use Lightweight Images
Prefer:
nginx:alpine
instead of:
nginx:latest
Use Environment Variables
Avoid storing secrets directly in code.
Keep Images Small
Smaller images:
- Deploy faster
- Use less storage
- Improve security
Enable Automatic Restart
docker run -d --restart always -p 80:80 mywebsite
Use Reverse Proxy
Popular choices:
- Nginx
- Traefik
- Caddy
Common Docker Errors and Solutions
| Error | Solution |
|---|---|
| Port already in use | Change port mapping |
| Permission denied | Use sudo |
| Container exits immediately | Check logs |
| Image not found | Build image again |
View logs:
docker logs container_id
Advantages of Docker Deployment
| Benefit | Description |
|---|---|
| Fast Deployment | Launch websites quickly |
| Easy Migration | Move between servers easily |
| Consistent Environment | No compatibility issues |
| Scalability | Run multiple containers |
| Simplified Maintenance | Easier updates and rollbacks |
