Ansible: how to run task on other host inside one playbook?
提问by Frexin
I'm writing ansible playbook for one specific goal: i'd like to sync directory on server A-n, but before i should make git pull on server "B". I launch playbook on host A-n (described in inventory). I also have playbook for "git pull" on server B. Is it possible to include one playbook in another? I don't know how, because ansible allow to specify only one host group in beginning of playbook.
我正在为一个特定目标编写 ansible playbook：我想在服务器 An 上同步目录，但在我应该在服务器“B”上进行 git pull 之前。我在主机 An 上启动剧本（在清单中描述）。我在服务器 B 上也有“git pull”的剧本。是否可以在另一个剧本中包含一个剧本？我不知道怎么做，因为 ansible 只允许在剧本开头指定一个主机组。

If you want to run a task that's associated with a host, but on different host, you should try delegate_to.
如果要运行与主机关联但在不同主机上的任务，则应尝试delegate_to.
