Environment Variables

Fig reads a number of environment variables. Some are required for base functionality while others can be used to override setting configuration without having to made code changes.

The following environment variables are available:

Category	Function	Format	Example
Mandatory - Basic Function	Specifies the location of the Fig API so the client knows where it should contact.	FIG_API_URI	FIG_API_URI=http://localhost:7281
Setting Configuration	Overrides the group attribute for a specific setting.	FIG_[SettingName]_GROUP	FIG_MYSETTING_GROUP = MyGroup
Setting Configuration	Overrides the Validation Regex attribute for a specific setting	FIG_[SettingName]_VALIDATIONREGEX	FIG_MYSETTING_VALIDATIONREGEX = \d
Setting Configuration	Overrides the Validation Explanation attribute for a specific setting	FIG_[SettingName]_VALIDATIONEXPLANATION	FIG_MYSETTING_VALIDATIONEXPLANATION = Number
Setting Configuration	Overrides the lookup table key attribute for a specific setting	FIG_[SettingName]_LOOKUPTABLEKEY	FIG_MYSETTING_LOOKUPTABLEKEY = MyLookup
Client Configuration	Sets the instance that this client should attempt to read. If instance does not exist, it will get the base settings.	FIG_[CLIENTNAME]_INSTANCE	FIG_MYCLIENT_INSTANCE = MyInstance
Client Configuration	Overrides the poll interval that will be used to poll the API for updates	FIG_POLL_INTERVAL_MS	FIG_POLL_INTERVAL_MS = 30000
