On our day 20 we have completed the Docker hands-on sessions, and I am certainly learning something valuable from this challenge.
Now it's time to take my Docker skills to the next level by creating a comprehensive cheat-sheet of all the commands i have learned so far. This cheat-sheet would include commands for both Docker and Docker Compose, along with brief explanations of their usage. This cheat-sheet will also serve as a valuable resource for the DevOps community.
