Not able to run demo/simple

[tzeller]

Looks like some services do not start properly when running the simple demo :

docker-compose -f demo/simple/docker-compose.yml up

simple-midpoint_server-1  |  [proxy:error] [pid 196:tid (111)Connection refused: AH00957: AJP: attempt to connect to 127.0.0.1:9090 (localhost) failed
...
simple-midpoint_server-1  | midpoint;midpoint.log;demo;;java.sql.SQLNonTransientConnectionException: Could not connect to address=(host=midpoint_data)(port=3306)(type=master) : Could not connect to midpoint_data:3306 : unexpected end of stream, read 0 bytes from 4 (socket was closed by server)
...

on an Apple M1 device, maybe that's the issue ?
