Nginx is a web server that can act as a reverse proxy, load balancer, or HTTPcache. By using Nginx, your application can handle a higher volume of requests with fewer resources compared to other web servers.

Docker is a popular containerization method to provide a lightweight and
scalable way to deploy applications. This article will guide you on how to run Nginx in a Docker Container so that you can quickly deploy the Nginx server for testing purposes, or easily scale out the Nginx server if needed in a production environment.

Prerequisites

To follow along with the step-by-step guidelines in the article, you need to
prepare the following prerequisites:

1. A ready-to-use Linux machine, such as an
Ubuntu version 22.04 server.
2. A recent version of Docker installed
and accessible without administration priviledge.

Deploy the Application With Docker Compose

To understand how Nginx works, let’s use Nginx to route traffic to a demo
application. In this section, you will deploy a demo application using Docker Compose.
