I'm not able to imagine the reason for the error, my dockercompose seems to be configured correctly.
I configured the right port, but I have these errors I tried to fix and I can't.

Answer 1

Production
In case of MySQL or PostgresSQL adapters, Konga will not perform db migrations when running in production mode.
You can manually perform the migrations by calling $ node ./bin/konga.js prepare , passing the args needed for the database connectivity.
so in first run,you need set NODE_ENV as development,not production
