Ensure Docker Compose is working by entering:

docker-compose version

To receive something like:

docker-compose version 1.27.2, build 8d51620a
docker-py version: 4.3.1
CPython version: 3.7.7
OpenSSL version: OpenSSL 1.1.1c  10 Sep 2019

Optionally, try entering:

docker run hello-world

To verify Docker can pull an image from Docker Hub and start containers as expected.
