Step 3: Verify that Nginx is running
To verify that Nginx is running on Docker, open your web browser and enter the IP address of your Docker host machine or localhost:
http://localhost
You should see the default Nginx welcome page.
🐳 How to Configure Nginx Server on Docker
Configuring Nginx Server on Docker involves several steps, including creating a new configuration file and mapping it to the container. The following instructions assume that you have already installed Nginx on Docker and created a new Docker container.
Subheading
Step 1: Create a new configuration file for Nginx
Create a new configuration file for Nginx using your preferred text editor.
nano nginx.conf
Subheading
Step 2: Add your Nginx configuration settings
Add your Nginx configuration settings to the new configuration file. You can use the default Nginx configuration settings or customize them for your web application.
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://yourapplication:3000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
Subheading
Step 3: Map the configuration file to the container
Map the configuration file to the container using the following command:
docker run -d -p 80:80 -v /path/to/nginx.conf:/etc/nginx/nginx.conf:ro nginx
This will map the new configuration file to the Nginx container and make it read-only.
