这是我到目前为止所做的：

vars 

delete_file_folder:
  - /home/ear
  - /home/war
  - /home/rar

deployment_file:
  - { fileLocation: "/home/ear_file",fileName: "fileA.war" }
  - { fileLocation: "/home/war",fileName: "fileB.war" }

config_file:
  - { fileLocation: "/home/config",fileName: "log4j2.xml" }
  - { fileLocation: "/home/config",fileName: "application.properties" }

rar_file: "fileC.rar"

这是我使用的剧本：

- find:
    paths: "{{ delete_file_folder }}"
    use_regex: yes
    patterns:
      - '.*@.*:.*:.*~$'
      - '.*\.backup.*$'
    age: 14d
  register: deleteFileReg

- file:
    path: "{{ item.path }}"
    state: absent
  loop: "{{ deleteFileReg.files }}"
