Using Nginx on Docker
Introduction
Nginx is a popular open-source web server known for its superior performance compared to the Apache web server. Nginx supports various functionalities, including deploying an API gateway (reverse proxy), load balancer, and email proxy. It was initially developed to build a web server capable of efficiently handling 10,000 concurrent connections with low memory usage.
Run Nginx with Docker
To use Nginx with Docker, simply execute the following command:
docker run -dp 8080:80 nginx:alpineBy default, Nginx uses port 80, but you can map it to a different port if needed.
Custom Nginx Configuration
To customize the Nginx configuration, first, create a ` docker-compose.yml` file with the following content:
services:
serviceName:
image: nginx:alpine
ports:
- 8080:80
volumes:
- ./default.conf:/etc/nginx/conf.d/default.conf
- ./index.html:/usr/share/nginx/html/index.htmlIn the ` volumes` field, note that I have mapped two files: ` default.conf` to change the default Nginx configuration and ` index.html` to customize the default interface when accessing the Nginx web view.
The content of the ` default.conf` file is as follows:
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
location / {
}
}This is the content of the ` index.html` file, which you can modify as needed:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Nginx</title>
</head>
<body>
<h1>This is custom index page</h1>
</body>
</html>After that, run Docker Compose with the following command:
docker compose up -dThe result will be as follows:
