The dreaded Java SpringBoot app not connecting to MySQL with Docker-compose java.net.ConnectException: Connection refused

Hi Folks,

I have been struggling with the following issue - the dreaded Java SpringBoot app not connecting to MySQL with docker compose exceptions:

com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

JDBCConnectionException: Unable to open JDBC Connection for DDL execution

java.net.ConnectException: Connection refused

The app works fine on its own, but it can't seem to connect to mysql once I get it in Docker. I am going out of my mind as I think I have all parameters correct, so any help is greatly appreciated! (:

So, I made some high speed opencv camera detection code, got it running on my debian labtop, and bought some 720p60 chinese usb cam. All worked well. However I wanted to make it run on my TinkerBoard S (tinkerOS - debian).

Here the camera simply refused to get detected, as my lsusb output hinted (also tried guvcview & cheese, none worked):

I am using the MYIR Z-turn Board MYS-7Z020. The included 8G SD card has a functioning System on it, the USB port is working here. The SD card has two partitions first partition FAT32 with boot.bin, devicetree, bitstream, kernel image and second partition ext3/4 rootfs ubuntu. I created a Vivado Project in Version 2019.1 with the example project delivered on CD with the Board. I had to correct a pin in the Zynq-7000 IP Core: MIO 51 for USB Reset wasn't set. The other Configurations are correctly i compared the IO settings with the included schematic.
