Where should I save a custom config file

[kn327]

I would like to override the ARDB config by providing an explicit environment variable for the ARDB data directory within docker

However, I cannot seem to get the instance to properly recognize the custom configuration file created

How is ardb being started in docker? The config file is the first argument when you start the server.
ardb-server your_custom_config.conf
