Step 4 : Add the Docker repository:

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.
