KC Quarkus cluster mode on AWS ECS Fargate

Okay !
I understand best now, Thank you again for the clarification.

Yes with this network mode, mapping should just work, and that explains how yuou get the right IP.

Unfortunately for me I cant use this mode,
but good news for anyone stepping by with such issues : is is possible to use the good old JDBC_PING
