我正在尝试运行一个容器，我需要将网络驱动程序用户作为“主机”而不是“桥接器”。我在 Centos 机器上运行它，我的 docker-compose.yml 是

version: '3.4'

services:
  testContainer:
    build:
      context: .
      args: 
        HADOOP_VERSION: 2.6.0
        HIVE_VERSION: 1.1.0
    image: testcontainer
    container_name: testcontainer
    hostname: testcontainer
    ports:
      - 9200:9200
      - 9300:9300
      - 5601:5601
      - 9001:9001
    ulimits:
      memlock:
        soft: -1
        hard: -1  
    networks:
      - elknet  

networks:
  elknet:
    driver: host      

但是当我启动“ docker-compose up ”时，我收到以下错误:

ERROR: only one instance of "host" network is allowed

任何人都可以建议我如何使用 docker-compose.yml 使用主机网络。
另请注意，如果我按照@larsks 的建议使用 network_host，我仍然会收到错误

version: '3.4'

services:
  testContainer:
    build:
      context: .
      args: 
        HADOOP_VERSION: 2.6.0
        HIVE_VERSION: 1.1.0
    image: testcontainer
    container_name: testcontainer
    hostname: testcontainer
    ports:
      - 9200:9200
      - 9300:9300
      - 5601:5601
      - 9001:9001
    ulimits:
      memlock:
        soft: -1
        hard: -1  
    network_mode: host

我收到以下错误

ERROR: The Compose file './docker-compose.yml' is invalid because:Unsupported config option for services: 'testContainer'

摆脱networks您的 docker-compose.yml 中的部分，并添加 network_mode对您的服务定义的指令:

services:
  testContainer:
    build:
      context: .
      args: 
        HADOOP_VERSION: 2.6.0
        HIVE_VERSION: 1.1.0
    image: testcontainer
    container_name: testcontainer
    hostname: testcontainer
    ports:
      - 9200:9200
      - 9300:9300
      - 5601:5601
      - 9001:9001
    ulimits:
      memlock:
        soft: -1
        hard: -1  
    network_mode: host
