Docker Challenge: Run Your First Container

Introduction

Welcome to the "Run Your First Container" challenge! You've already learned how to run the hello-world container. Now, let's take it a step further and run a different, interesting container. In this challenge, you'll use your newly acquired Docker skills to run a container that displays a fun message.

Run a New Container

Tasks

Your task is simple:

Run a Docker container based on the docker/getting-started image.

Requirements

To complete this challenge, you must:

Use the docker run command to start the container.
Use the image docker/getting-started.
Execute the command in the ~/project directory.

Example

When you successfully run the container, you should see output that includes some information about Docker.

Don't worry if you see a warning message about the /docker-entrypoint.d/ directory not being empty.

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration

2024/10/29 09:26:17 [notice] 1#1: start worker process 32

You can open a new terminal window to verify that the container is running by using the docker ps command.

docker ps

Note: Don't exit the terminal before you click the Continue button.

Summary

In this challenge, you've expanded your Docker skills by running a new container. You've used the docker run command to start a container from the docker/getting-started image, which displays some introductory information about Docker. This exercise reinforces your understanding of how to use Docker to run containers and introduces you to a new, informative Docker image. It's a great way to see how Docker can be used to quickly access and run pre-configured applications. Keep exploring different Docker images to continue expanding your containerization skills!
