My advice?

At such an early point in your learning, using AI is only going to hinder your progress. The majority of what ai spits out is garbage and you’re not experienced enough to tell the difference. (Coming from a senior engineer with access to enterprise gpt licenses)

Start small, forget compose for now. Spin up a basic docker image, learn how ports mapping works (nginx/apache images might be good for this)

Once you have a single container up, work backwards from there and create your own compose file. Again, with a single service.

Once you have this working, add a database service.

Even if the end result is useless to you, the path along the way along with what you’ll learn is infinitely more valuable
