in the compiled release my files from the config folder are not included, instead links are made to my folder on the computer I work on, I don’t understand how to correctly specify in rebar.config where to get the files for inclusion in the release?
Are you using rebar3 to build your releases? I vaguely remember it would create symlinks in dev mode and actually copy files around in prod mode. So perhaps rebar3 as prod release command should do it for you.
Yup, uses symlinks by default. Use rebar3 as prod release to get a copy.
