SQL for armf error even after trying tobi321:rpi-mariadb
Raspberry Pi 4; Getting an sql for armf error when following tutorial i even tried tobi321:rpi-mariadb it says the server is starting
Rails has a delayed logs buffer flush so server is starting is actually ok - give a moment and it should be up and running
can you verify that?
its up and running in the log, but still can't access it no port mapping on docker please check the image attached 
Container Log
see where a bundled gem is installed.

I have a similar issue on a raspberry pi 4b. Since mysql isnt available, i switched to tobi's mariadb and when i start the containers 4 of them decide not to play:
syncing-server_api-gateway_1 ./wait-for.sh syncing-serv ... Exit 1
syncing-server_auth_1 ./wait-for.sh syncing-serv ... Exit 1

they all have the same error:
