In this project, you will write a basic Dockerfile to create a Docker image. When this Docker image is run, it should print "Hello, Captain!" to the console before exiting.

Requirements

• The Dockerfile should be named Dockerfile.
• The Dockerfile should be in the root directory of the project.
• The base image should be alpine:latest.
• The Dockerfile should contain a single instruction to print "Hello, Captain!" to the console before exiting.

You can learn more about writing a Dockerfile here.

If you are looking to build a more advanced version of this project, you can consider adding the ability to pass your name to the Docker image as an argument, and have the Docker image print "Hello, [your name]!" instead of "Hello, Captain!".
