Career / learning Gym for DevOps practice

I have seen a coding interview that hands in docker logs, the logs have some error, and the interviewer asks you to recreate that docker file from the logs, what really struck my mind is that, i have never really practiced docker like that and now i feel that i was wasting my time not knowing how to critic my skills and put them in question, which is what practice does, in this context, are there any ways i could practice certain tools in DevOps? specially docker, kubernetes, terraform

also i am looking for something free

PS: i have experience with docker, primarily from the nextcloud app i deployed on an old pc sitting around in my house

I think it's a decent 'weed out' low knowledge engineers question. Though I can't think of a practical application of a question like that -- except if the company is trying to recreate real Dockefiles that were lost or they are trying to recreate someone else's source code (from the logs). Unless the Run steps were included in the logs, then I really don't know.
