$HOME/.balenarc.yml.$PWD/balenarc.yml.- Environment variables matching
BALENARC_<SETTING_NAME>.
Windows:
- Default settings.
%UserProfile%\_balenarc.yml.%cd%\balenarc.yml.- Environment variables matching
BALENARC_<SETTING_NAME>.
The values from all locations are merged together, with sources listed below taking precedence.
For example:
$ cat $HOME/.balenarc.yml
balenaUrl: 'balena-staging.com'
projectsDirectory: '/opt/balena'
$ cat $PWD/.balenarc.yml
projectsDirectory: '/Users/balena/Projects'
dataDirectory: '/opt/balena-data'
$ echo $BALENARC_DATA_DIRECTORY
/opt/cache/balenaThat specific environment will have the following configuration:
balenaUrl: 'balena-staging.com'
projectsDirectory: '/Users/balena/Projects'

This module is intended to only provide read only access to the settings. Balena settings client reads settings from various locations, like a local balenarc file and a per user config file, therefore the module doesn't know where to write changes back.
If you want to persist data related to balena, consider using balena settings storage instead.
