当 Ansible Playbook 中的任何包失败时如何进入救援模块

我有一个简单的 playbook，用于在本地系统中安装一堆软件包，希望当安装过程中出现任何故障时，我的 playbook 能够退出循环并转到救援模块进行恢复。但是我的 ansible playbook 试图部署所有软件包，即使出现故障，并且 playbook 在迭代所有软件包后调用救援模块。

如果第一个包出现任何故障，它就不应该迭代第二个包。

- hosts: localhost
  tasks:
    - name: Deploy all packages
      block:
         - name: installing debian packages
           apt:
              deb: "{{ item }}"
           with_items:
              - /home/playbook/sample1.deb
              - /home/playbook/sample2.deb
           when: ansible_distribution == "Ubuntu"
      rescue:
         - name:  Deployment of debian package is Failed
           debug: msg="There was Failure installing Package"

电流输出：

ansible-playbook installdeb.yml

当我按如下方式修改剧本时，它就按预期工作了。

- hosts: localhost
  tasks:
    - name: Deploy all packages
      block:
         - name: installing debian packages
           apt:
              deb: "{{ item }}"
           register: apt_output
           with_items:
              - /home/playbook/sample1.deb
              - /home/playbook/sample2.deb
           when: (not (apt_output |default({})) is failed) and (ansible_distribution == "Ubuntu")
      rescue:
         - name:  Deployment of debian package is Failed
           debug: msg="There was Failure installing Package"

测试输出：

ansible-playbook installdeb.yml
