Ansible 可从主机读取ip地址

我需要将日期设置为远程主机，因此我读取localhost date，然后需要获取ansible的hosts文件中定义的其他主机“ipv4\U地址”

- hosts: localhost
  become_user : root
  tasks:

    - name: align datetime
      shell: |
                 data="$(date +'%Y/%m/%d +%H:%m:00')"
                 ssh  user@{{ otherhost.ipv4_address }} "sudo date -s $data"

- hosts: otherhost
  become: true
his tasks....

但这似乎不是获得ipv4的正确方法：

致命：[127.0.0.1]：失败！=>{“msg”：“该任务包含一个选项 使用未定义的变量。错误为：“otherhost.ipv4\u地址”为 未定义\n\n错误似乎在

问题是，

{{otherhost.ipv4\u address}}

在您使用它时不可用，因为您没有收集到有关

otherhost

的事实

您可以选择以下几个选项：

例如，在开始使用数据之前收集事实

例如，在远程主机上运行playbook，并提前委派本地主机时间

这利用了ansibles自动ssh插入目标框的方式，您无需手动

ssh
