Docker Desktop overview - Mini Project: Build & Apply

Docker Desktop overview

📖 Scenario: You are starting to learn Docker on your computer using Docker Desktop. Docker Desktop helps you run containers easily on your laptop or desktop.In this project, you will create a simple Docker setup step-by-step to understand how Docker Desktop works with images and containers.

🎯 Goal: You will create a Dockerfile, build a Docker image, run a container from that image, and see the output from the container using Docker Desktop.

📋 What You'll Learn

Create a Dockerfile with a base image and a command

Build a Docker image with a specific name

Run a container from the built image

Display the output from the running container

💡 Why This Matters

🌍 Real World

Docker Desktop is used by developers to build, test, and run containerized applications easily on their local machines.

💼 Career

Understanding Docker Desktop is essential for roles in DevOps, software development, and system administration to manage containerized environments.

1

Create a Dockerfile

Create a file named Dockerfile with these exact contents:
FROM alpine:latest
CMD ["echo", "Hello from Docker Desktop!"]

Docker

# Create a Dockerfile with FROM alpine:latest and CMD ["echo", "Hello from Docker Desktop!"]

Need a hint?

The Dockerfile must start with FROM alpine:latest and use CMD to run the echo command.

2

Build the Docker image

Use the Docker CLI command to build an image named mydockerdesktop from the current directory with the Dockerfile you created. Write the exact command:
docker build -t mydockerdesktop .

Docker

FROM alpine:latest
CMD ["echo", "Hello from Docker Desktop!"]
# Write the docker build command to create image mydockerdesktop
# Your code here

Need a hint?

Use docker build with -t mydockerdesktop and . to build the image from the current folder.

3

Run a container from the image

Write the Docker CLI command to run a container from the image mydockerdesktop and show its output. Use the exact command:
docker run mydockerdesktop

Docker

# Write the docker run command to start a container from mydockerdesktop
# Your code here

Need a hint?

Use docker run followed by the image name to start the container and see the output.

4

See the output from the container

Run the full Docker commands and write the exact output you see from running docker run mydockerdesktop. The output should be:
Hello from Docker Desktop!

Docker

# Write the output you see below
# Your code here

Need a hint?

After running the container, the output should exactly say Hello from Docker Desktop!
