windows - Ansible Chocolatey - 只是想更新软件包(如果有)

Question

我有一个使用 Chocolatey 开发的 ansible 剧本来升级一组软件包。但是，我希望剧本仅在已安装的情况下升级软件包，如果该软件包不存在则跳过。然而，剧本正在做的是升级现有的软件包，但安装不存在的软件包。我从剧本中知道它正在做它应该做的事情，因为状态被设置为最新。我想知道的是如何修改剧本以仅升级现有的软件包(可能使用 when: 语句)，但我似乎找不到任何可以帮助解决这个问题的东西。提前致谢。

下面是 ansible 剧本。是的，我知道我可以将这些包包含在一个循环中，而不是一次运行一个包，但我发现这并不像我想要的那么冗长。

Answer 1

您需要做的是首先检查安装了哪些软件包，您可以使用 win_chocolatey_facts 来执行此操作模块。

如果您只想更新所有已安装的软件包，那么您可以循环该模块返回的内容并进行更新:

---
- hosts: all
  tasks:
    - name: Gather facts from Chocolatey CLI
      win_chocolatey_facts:

    - name: Upgrade installed packages
      win_chocolatey:
        name: '{{ item.package }}'
        state: latest
      failed_when: false # Setting this means if one package fails, the loop will continue. You can remove it if you don't want that behaviour.
      loop: '{{ ansible_chocolatey.packages }}' # This variable comes from the facts task above automatically.
...

如果您只想关心列表与计算机上的包之间的交集，那么我建议将该包列表存储在变量中并在循环中检查它。

---
- hosts: all
  vars:
    chocolatey_packages_to_upgrade:
      - putty
      - winscp
      - notepadplusplus
      - sql-server-management-studio
      - firefox
      - googlechrome
      - brave
      - 7zip
      - treesizefree
      - wireshark
      - powerbigateway

  tasks:
    - name: Gather facts from Chocolatey CLI
      win_chocolatey_facts:

    - name: Upgrade installed packages
      win_chocolatey:
        name: '{{ item.package }}'
        state: latest
      when: item.package in chocolatey_packages_to_upgrade # Only process this package if the package is in the predefined list
      failed_when: false # Setting this means if one package fails, the loop will continue. You can remove it if you don't want that behaviour.
      loop: '{{ ansible_chocolatey.packages }}' # This variable comes from the facts task above automatically.
...

您始终可以反转此循环，即您可以在所需的包上循环，并且仅在事实模块的自动变量中找到它们时才进行升级。

此外，如果您根本不想使用循环，您仍然可以像这样执行单独的任务:

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