Functions

func Init

func Init()

Init should be called at the beginning of execution to load base configuration and generate dependent configuration files. The defaults for the config package will be loaded from values defined in defaults.yaml in this package, then overridden the corresponding environment variables.

func InitBifrost

func InitBifrost()

func InitThornode

func InitThornode(ctx context.Context)
