Thx. Yeah I never really liked that anyway.

Since you are talking about the ENV variables I think this should be implemented in the config library container-app-conf (I will create an issue there). Since I do like it to be able to use the hyphen variant in the yaml config, allowing both the hyphen and underscore variant in the ENV source should fix this right?

[zaggash]

Yeah, I think a conversion from hyphen to underscore in the config library is the way to go ;)
Thanks for taking care of it ;)

However, it will be a breaking change on this app tho for those like me who uses the current implementation.
Nevermind, I didn't pay attention you planned to allow both spelling.

Should be fixed with the new release, report back if it isn't.
