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!

Protip: you can configure the default host bind IP via /etc/docker/daemon.json. You could for example set:

{
  "ip": "127.0.0.1"
}

which would result in -p "8080:8080" being equivalent to -p "127.0.0.1:8080:8080"
