# syntax=docker/dockerfile:1
FROM busybox
CMD echo "Hello world! This is my first Docker image."

Run

docker build -t <your_username>/my-private-repo .

to build your Docker image.

Run

docker run <your_username>/my-private-repo 

to test your Docker image locally.

Run

docker push <your_username>/my-private-repo
