在Ansible
Playbook中，泊坞窗参数extra_host包含两部分主机：ip_address。我正在尝试将主机和ipaddress作为变量传递。它们来自即时变量。我的主机文件的最终结果是：1.2.3.4
{{server_hostname}}。这是代码：

vars_prompt:
  - name: "server_ip"
    prompt: "Please enter the server IP address"
    private: no

  - name: "server_hostname"
    prompt: "Please enter the server hostname"
    private: no

tasks:    
  - name: Install Tomcat
    docker:
      image: tomcat:8.0
      pull: missing
      name: tomcat
      state: restarted
      ports: 
        - "8080:8080"
        - "443:443"
      extra_hosts:
        "{{server_hostname}}": "{{server_ip}}"

我不熟悉ansible剧本，对您的帮助将不胜感激。
