func GetenvFS

func GetenvFS(fsys fs.FS, key string, def ...string) string

GetenvFS retrieves the value of the environment variable named by the key. If the variable is unset, but the same variable ending in `_FILE` is set, the referenced file (resolved from the given filesystem) will be read into the value. Otherwise the provided default (or an emptry string) is returned.
