Docker结合网络和“内部”属性示例

我试图在docker-compose.yml v2中找到带有网络声明的用法“ internal”属性的示例.

我搜索如何做这句话：

docker network create someName --internal

但在docker-compose.yml中.

尝试使用此变体时出现错误：

version: '2'

services:
# services definition

networks:
  someName:
    internal: true

错误信息：

The Compose file '.docker-compose.yml' is invalid because:
networks.someName value Additional properties are not allowed ('internal' was unexpected)
