docker-compose.yml 增加 extra_hosts

services:
  xx:
    container_name: "xx"
    image: my_image
    network_mode: host
    extra_hosts:
      - "ims.gd.chinamobile.com:162.242.195.82" #host and ip
      - "ims.sbc1.chinamobile.com ims.sbc2.chinamobile.com:50.31.209.229"
    logging:
      driver: "json-file"
      options:
        max-file: "10"
        max-size: "200m"
    restart: always
    env_file: ./.env
    ulimits:
      core: -1
    privileged: true
    stdin_open: true
    tty: true
    volumes:
      - ./data/log:/var/log

搞定！

进到容器，`cat /etc/hosts`，正是上面配置的内容

再定义一个全局变量， sip_gethostbyname=true

现在配置一个向 IMS 注册的 Fs 网关，就易如反掌了
