Using MariaDB on NetPi

[Armin@netPI]

But Phil, here is what I can tell you. If you script runs in the same container as mariadb, then port mapping is not necessary at all and also using the host mode isn't.

I suppose you python script addresses an IP address to get in touch with the container ... and likely it is the Rpi IP address (I suppose).

But if phython runs in the same container then the context to address ports in the same container is the IP address 127.0.0.1:port and not any IP address of the "outside world".

So try this IP address locally or use "localhost:port" as address
