Недопустимое свойство верхнего уровня "network_mode" из docker -compose

Question

Я хочу использовать network_mode: "host" при docker -композиции, но она была отклонена.

$ cat docker-compose.yml
version: "3.7"
services:
  hello:
    image: hello-world:latest
$ docker-compose up
Creating network "tmp_default" with the default driver
Creating tmp_hello_1 ... done
Attaching to tmp_hello_1
hello_1  |
hello_1  | Hello from Docker!
hello_1  | This message shows that your installation appears to be working correctly.
:
tmp_hello_1 exited with code 0

OK. Позвольте мне использовать network_mode: "host"

$ nano docker-compose.yml
$ cat docker-compose.yml
version: "3.7"
network_mode: "host"
services:
  hello:
    image: hello-world:latest
$ docker-compose up
ERROR: The Compose file './docker-compose.yml' is invalid because:
Invalid top-level property "network_mode". Valid top-level sections for this Compose file are: version, services, networks, volumes, secrets, configs, and extensions starting with "x-".

WHY !? это официально не так ли? https://docs.docker.com/compose/compose-file/#network_mode

$ docker-compose -v
docker-compose version 1.24.1, build 4667896b
$ docker -v
Docker version 19.03.2, build 6a30dfca03
$  cat /etc/os-release

network_mode не является свойством верхнего уровня. Запишите это под обслуживание.

version: "3.7"
services:
  hello:
    network_mode: "host"
    image: hello-world:latest
