CMD ["python","hello_world_ml.py"]

🏗️ Step 2: Build the Docker Image

Use the command below to build the image from the Dockerfile.

Git is a version control system that helps track code changes, manage versions, and enable collaboration among developers. GitHub is an online platform that hosts Git repositories, allowing you to store code in the cloud and collaborate with others.

`git diff`	Shows the difference between modified files and the last committed version.
`git log`	Displays a list of all commits made in the repository’s history.
`git clone`	Creates a local copy of a remote Git repository.
`git pull`	Fetches and merges changes from a remote repository into your current branch.
`git push`	Uploads your local commits to a remote repository.
