Ansible：如何在运行 Ansible Playbook 时删除/重新创建文件？

已发表: 2019-08-29

Ansible - 如何删除重新创建文件？

Ansible 无疑是世界上财富 500 强公司使用的最好的基础设施自动化工具。

在 Crunchify 上，我们发布了关于 Ansible 的大量教程。 请查看 Ansible Archive 以获取所有详细教程。 以下是前 3 个教程。

  1. 如何将文件、目录或脚本从本地主机复制到远程主机？
  2. 如何使用 Ansible 生成 Amazon EC2 虚拟机？
  3. 如何在远程主机上执行命令并返回命令结果（日志）？

在本教程中，我们将介绍我日常使用的 3 个不同的技巧。

如何使用 Ansible 删除和重新创建文件？

第1步

确保您已在 Mac 或 Linux 操作系统上正确设置 Ansible。

第2步

- name : Delete and Re - Create crunchify . txt file from current directory .
   hosts : local
   connection : local
   gather_facts : True
 
   tasks :
    - name : delete file
       ignore_errors : yes
       file :
         state : absent
         path : crunchify . txt
 
    - name : Ansible create file if it doesn ' t exist example
       ignore_errors : yes
       file :
         path : "crunchify.txt"
         state : touch

第三步

打开hosts文件并输入以下内容：

[ local ]
localhost ansible_connection = local ansible_python_interpreter = python

第四步

如何在运行 Ansible Playbook 时删除/重新创建文件？

运行Ansible playbook 。

localhost                    : ok = 3      changed = 2      unreachable = 0      failed = 0

就是这样。 以上 Ansible playbook 将删除一个名为crunchify.txt的现有文件，并创建一个内容为空的新文件。

像往常一样，让我们​​知道在 Ansible Playbook 上运行的任何查询或任何问题。
