I'll start:

When I was first learning to use Docker, I didn't realize that most tutorials that include a database don't configure the database to persist. Imagine my surprise when I couldn't figure out why the database kept getting wiped!

Using Docker Desktop at work without a license. Use Rancher Desktop instead. It's essentially like what Oracle did with the Oracle JDK. To my knowledge they haven't gone after anyone but it is technically a license violation to use it for work without a license. I could not (easily) find a way to install Docker on Mac without using Docker Desktop but Rancher Desktop worked fine.

Also, podman exists as a drop in replacement for Docker for the curious. I haven't tried it myself though so this isn't a recommendation.
