      compose := tf.Cmd("docker", "compose", "-f", dcBase, "-f", dcMySQL, "down", "--volumes", "--remove-orphans")
      if err := compose.Run(); err != nil {
        tf.Fatalf(":heavy_exclamation_mark: docker-compose down failed: [%v]", err)
      }
      tf.Log(":white_check_mark: docker-compose ran successfully")
