Sorry guys, I realized it is a spoiler, but I didn’t feel that way when using the screenshots because when you arrive at this point, you already did the hard part. I will blur the machine name this evening in the article.
About how the box initial state:
- There is no container running (
docker psreturns no container). - An Ubuntu image has already been pulled and
docker imagereturns a result with 1 image. - A harder way would be to have to copy an image and a Dockerfile to exploit them (which should usually be easy with an internet connection as you can pull images from Docker Hub)
