仅当ansible中满足x任务条件时才运行yz任务

团队， 我有10个任务，只有在满足task1中的条件时，我才想运行2-10

- name: 1Check if the node needs to be processed
  stat: /tmp/fscache-cleaned-up1.log
  register: dc_status

。。 .. ..

您必须在stat模块调用中使用“path”和“block”来组合相关任务，如下所示：

- name: Check if the node needs to be processed
  stat:
    path: /tmp/fscache-cleaned-up1.log
  register: dc_status

- name: Run this only when the log file exists
  block:
    - name: Install something
      yum:
        name:
        - somepackage
        state: present

     - name: Apply a config template
      template:
        src: templates/src.j2
        dest: /etc/foo.conf

    - name: Start a service and enable it
      service:
        name: bar
        state: started
        enabled: True
  when: 
    - dc_status.stat.exists
    - dc_status.stat.is_file

其他资料：

- name: Check if the node needs to be processed
  stat:
    path: /tmp/fscache-cleaned-up1.log
  register: dc_status

- name: Run this only when the log file exists
  block:
    - name: Install something
      yum:
        name:
        - somepackage
        state: present

     - name: Apply a config template
      template:
        src: templates/src.j2
        dest: /etc/foo.conf

    - name: Start a service and enable it
      service:
        name: bar
        state: started
        enabled: True
  when: 
    - dc_status.stat.exists
    - dc_status.stat.is_file
