🎯 Goal: Learn how to run a Docker container using the docker run command with specific options to start a web server and expose it to your computer.

📋 What You'll Learn

Use the official nginx Docker image

Run the container in detached mode

Map port 8080 on your computer to port 80 in the container

Name the container mynginx

💡 Why This Matters

🌍 Real World

Running containers is how many developers and system administrators deploy applications quickly and consistently on any machine.

💼 Career

Knowing how to use <code>docker run</code> is a fundamental skill for DevOps roles, cloud engineers, and software developers working with containerized applications.

1

Pull the nginx image

Write the docker pull nginx command to download the official nginx image from Docker Hub.

Docker

# Write the command to pull the nginx image
# Your code here

Need a hint?

Use docker pull nginx to get the image from Docker Hub.

2

Run nginx container in detached mode

Write the docker run command to start a container named mynginx from the nginx image in detached mode.

Docker

docker pull nginx
# Run the nginx container named mynginx in detached mode
# Your code here

Need a hint?

Use docker run --name mynginx -d nginx to start the container in the background.

3

Map port 8080 to port 80

Modify the docker run command to map port 8080 on your computer to port 80 inside the container.

Docker

docker pull nginx
docker run --name mynginx -d nginx
# Add port mapping from 8080 to 80
# Your code here

Need a hint?

Add -p 8080:80 to map ports.

4

Verify the container is running

Write the docker ps command to list running containers and verify mynginx is running.

Docker

docker pull nginx
docker run --name mynginx -d -p 8080:80 nginx
# List running containers
# Your code here

Need a hint?

Use docker ps to see running containers.
