go - Config file masks -

-

we deploy services docker containers using marathon. containers include base config file, marathon pulls environment config file (which has subset of base keys) @ deployment time when app starts has;

  • environment.toml
  • config.toml

when reading config need conflate values in both files single set, masking/shadowing values present in both files in environment file.

i didn't find functionality in viper docs. unless have missed seems options are;

  • write package uses viper read both files , perform conflation.
  • extend viper

before start writing code, there mechanism doing this?
