Documentation

This module attempts to retrieve configuration from the following places:

UNIX:

• Default settings.
• $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/balena

That specific environment will have the following configuration:

	balenaUrl: 'balena-staging.com'
	projectsDirectory: '/Users/balena/Projects'
	dataDirectory: '/opt/cache/balena'

Modifying settings

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.
