使用ansible的同学都知道,ansible只支持新增删除具体的某个文件夹或者文件,如下所示:
1. 创建目录,删除整个目录
- name: Create a directory if it does not exist file: path: /appvol/some_directory state: directory mode: '0755' - name: Remove a directory if it exist file: path: /appvol/some_directory state: absent
2.创建文件,删除单个文件
- name: Create a file if it does not exist file: path: /appvol/some_directory/hello.txt state: touch mode: '0755' - name: Remove a file if it exist file: path: /appvol/some_directory/hello.txt state: absent
对于某些场景,我们想清空log文件夹或者缓存文件夹,这个时候就仅仅需要删除目录下的所有内容而已。
3.删除某个目录下的所有文件,或者符合条件的文件名
#先使用shell模块获取该目录下所有文件名,并且存储到一个变量files_list
- name: list the files of dir some_directory shell: ls args: chdir: /appvol/some_directory register: files_list #使用with_items属性,将files_list变量以lines的形式输出,再借助file模块循环删除每个文件 - name: Remove a directory if it does not exist file: path: /appvol/some_directory/{{ item }} state: absent with_items: - "{{ files_list.stdout_lines }}"
