Hi ,

What was your goal? There is a docker/whalesay image and a hello-world image. The whalesay image description is on Docker Hub

https://hub.docker.com/r/docker/whalesay

And the example command shows that you need to use the cowsay command.

docker run docker/whalesay cowsay boo

“boo” could be “hello-world” too
