如何修改Ansible Playbook实现仅更新已安装的Chocolatey包？

要实现仅升级已安装的Chocolatey包，你需要先收集目标机器上已安装的Chocolatey包信息，再通过when条件判断每个包是否已安装，仅对已安装的包执行升级操作。

- hosts: all

    - name: 收集已安装的Chocolatey包信息
      win_chocolatey_facts:

    - name: Update putty on Windows machines

    - name: Update Notepad++ on Windows machines
      win_chocolatey:

    - name: Update SQL Server Management Studio on Windows machines
      win_chocolatey:

      when: "'sql-server-management-studio' in ansible_chocolatey.packages"

    - name: Update Firefox on Windows machines
      win_chocolatey:
        name: firefox
        state: latest
      when: "'firefox' in ansible_chocolatey.packages"

    - name: Update Google Chrome on Windows machines
      win_chocolatey:
        name: googlechrome
        state: latest
      when: "'googlechrome' in ansible_chocolatey.packages"

    - name: Update Brave Browser on Windows machines
      win_chocolatey:
        name: brave
        state: latest
      when: "'brave' in ansible_chocolatey.packages"

    - name: Update 7zip on Windows machines
      win_chocolatey:
        name: 7zip
        state: latest
      when: "'7zip' in ansible_chocolatey.packages"

    - name: Update TreeSize Free on Windows machines
      win_chocolatey:
        name: treesizefree
        state: latest
      when: "'treesizefree' in ansible_chocolatey.packages"

    - name: Update Wireshark on Windows machines
      win_chocolatey:
        name: wireshark
        state: latest
      when: "'wireshark' in ansible_chocolatey.packages"

    - name: Update PowerBI data gateway on Windows machines
      win_chocolatey:
        name: powerbigateway
        state: latest
      when: "'powerbigateway' in ansible_chocolatey.packages"

    - name: Update RVTools on Windows machines
      win_chocolatey:
        name: rvtools
        state: latest
      when: "'rvtools' in ansible_chocolatey.packages"

原理说明 #

1. win_chocolatey_facts模块会在目标Windows机器上收集所有已安装的Chocolatey包信息，并将其存储在ansible_chocolatey.packages变量中——这个变量是一个字典，键为Chocolatey包名，值为对应的包详情。
2. 每个升级任务中的when条件会检查当前包名是否存在于ansible_chocolatey.packages的键集合中：
   • 若存在，说明包已安装，执行升级操作；
   • 若不存在，直接跳过该任务，不会自动安装包。

这种方式既保留了你需要的单独任务详细输出，又实现了仅升级已安装包的需求。
