Allow initial custom configuration on startup #5

Closed indigo423 closed 6 years ago

indigo423 commented 7 years ago

As a user, I would like to have a configuration directory which allows me to overwrite just specific configuration files on startup. For example, I have just changed the poller-configuration.xml, there should be a directory which gives me the possibility to overwrite just this file from the pristine config.

Do you mean, whatever files you put into the directory are imported directly over top of the files that exist in the container? Do you envision this primarily as a one-time option for initial configuration?

@gallenc came up with this use case and I documented it here so it's not forgotten. There is one problem, you can only copy files into the container during build-time not runtime. Our configuration is not made for running in a container, so having them accessible persisted somewhere is the only solution I can think of right now. But happy for any input here.
