如何用ansible升级单个包？

  • 772

我正在尝试编写一个仅升级linux-generic软件包但无法找到使其实际工作的魔法咒语的 ansible 剧本。通过这个游戏，我得到了parameters are mutually exclusive: deb|package|upgrade谷歌建议的错误，这upgrade: full不是针对单个包的：

  - name: Check if linux-generic is installed
    command: dpkg -l linux-generic
    register: pkg_chk

  - name: update kernel if installed
    when: pkg_chk.rc == 0
    apt:
      update_cache: yes
      autoremove  : yes
      autoclean   : no
      upgrade     : full
      dpkg_options: 'force-confold,force-confdef'
      name        : linux-generic

删除upgrade: full运行播放...

TASK [update kernel if installed] **********************************************************
ok: [vivaldi.fammed.wisc.edu]

但是，当我登录到机器并运行aptitude full-upgrade它时，显示 ansible 没有做任何事情：

# aptitude full-upgrade
The following NEW packages will be installed:
  linux-headers-4.4.0-203{a} linux-headers-4.4.0-203-generic{a}
  linux-image-4.4.0-203-generic{a} linux-modules-4.4.0-203-generic{a}
  linux-modules-extra-4.4.0-203-generic{a}

好的，所以我想我只是将command:模块扔给它并使用裸apt命令，但是命令字符串存在一些问题，我没有正确转义。

  - name: upgrade linux-generic
    when: pkg_chk.rc == 0
      command: apt-get install -y --only-upgrade -o Dpkg::Options::='force-confdef' -o Dpkg::Options::='force-confold' linux-generic
      register: install_chk

  - name: autoremove linux-generic
    when: install_chk.rc == 0
      command: apt-get -y autoremove -o Dpkg::Options::='force-confdef' -o Dpkg::Options::='force-confold'
      register: auto_chk

这会产生这个错误：

Syntax Error while loading YAML.
  mapping values are not allowed in this context
    The error appears to be in '/usr/src/ansible/tests/upgrade-kernel-only.yml': line 24, column 12, but may
    be elsewhere in the file depending on the exact syntax problem.
    
    The offending line appears to be:
    
        when: pkg_chk.rc == 0
          command: apt-get install -y --only-upgrade -o Dpkg::Options::='force-confdef' -o Dpkg::Options::='force-confold' linux-generic
               ^ here

我试过转义: =字符，以及替换双引号和单引号。任何人都知道如何让这个工作？

    您是否有任何具体原因不考虑 ansible 包模块，例如

    - name: Install linux-generic
  package:
    name: linux-generic
    state: present

    就 ansible 错误而言，您必须将命令用双引号引起来，因为您在内部使用单引号：

     - name: upgrade linux-generic
    when: pkg_chk.rc == 0
      command: "apt-get install -y --only-upgrade -o Dpkg::Options::='force-confdef' -o Dpkg::Options::='force-confold' linux-generic"
      register: install_chk

  - name: autoremove linux-generic
    when: install_chk.rc == 0
      command: "apt-get -y autoremove -o Dpkg::Options::='force-confdef' -o Dpkg::Options::='force-confold'"
      register: auto_chk
