如何查看运行它的容器而不是清单中提供的服务器

Question

设置：Ansible 在 docker 容器内初始化和运行。包含剧本和库存文件的 git 存储库被加载到此容器中。

playbook 的作用：我正在编写的特定 playbook 在清单中列出的所有主机上运行一个简单的 findmnt，并将输出写入一个平面 txt 文件，然后我正在获取该文件。

实际问题：ansible 容器未在分离模式下运行，因此运行完成后，无法检索这些结果 txt 文件。由于容器中有一个 git repo 分层，我尝试将这些存储到其中，但该命令再次在库存主机上执行，而不是在运行 Ansible 的容器上执行。我尝试了多种方法来做同样的事情，但我无法找到一种方法让 ansible 在运行它的容器中执行一组操作。我该如何处理这种情况。

您可以delegate_to: 127.0.0.1 或在每个任务的基础上使用简写local_action（参考https://docs.ansible.com/ansible/latest/user_guide/playbooks_delegation.html），例如：

---
- hosts: all
  tasks:
  - name: run task on inventory hosts
    debug: 
      msg: 'this task will execute on all hosts'

  - name: delegate task to 127.0.0.1
    debug: 
      msg: 'this task is delegated to the ansible control server'
    delegate_to: 127.0.0.1

  - name: use the local_action syntax for delegation
    local_action:
      module: debug
      msg: 'executing on the control server'
