Run an Nginx container using the Docker command

Here's how you can run an Nginx container using the Docker command:

Step 10 : Pull the Nginx image from the Docker Hub:

docker pull nginx

Step 11 : Start an Nginx container:

docker run --name mynginx -p 80:80 -d nginx

• The --name option gives the container a name.
• The -p option maps the host's port 80 to the container's port 80.
• The -d option runs the container in the background.

Step 12 : Verify that the container is running:

docker ps

Step 13 : Access the Nginx server:

• Open your web browser and navigate to http://<host-IP>.
• Replace <host-IP> with the IP address of the host machine.
