Functions

func ExpandEnv

func ExpandEnv(s []byte) []byte

ExpandEnv looks for ${var} in s and replaces them with value of the corresponding environment variable. It's not like os.ExpandEnv which handles both ${var} and $var. $var is considered invalid, since configurations like password for redis/mysql may contain $.
