My AzerothCore docker-compose fails with the following:

The real error was right before the database logs:
ac-worldserver_1 | Map file '/azeroth-server/data/maps/0004331.map': does not exist!
which means: the datafiles are missing.
As the official guide said, I had to:
Put your data files into the docker/worldserver/data/ folder that is inside azerothcore-wotlk.
I was having problems after docker-compose-up creating database which world kept shutting down and having this on log

azerothcore-wotlk_ac-worldserver_1 exited with code 137
Which fixed by increasing memory from default 1 gb to 2 gb. Here is how to increase https://www.petefreitag.com/item/848.cfm
