When does this error pop up?

The error occurs when trying to start using the commands shown in README:

docker run -d --network ep_network -e MYSQL_ROOT_PASSWORD=12345 --name ep_mysql mysql && sleep 10 && docker run --network ep_network -e ETHERPAD_DB_HOST=ep_mysql -e ETHERPAD_DB_PASSWORD=12345 -p 9001:9001 --name=ep_app tvelocity/etherpad-lite.

Appears to be an incompatibility with mysql:latest (atm 8.0.11), forcing mysql:5 (5.7.22) seems to work
