使用 Ansible 包管理显示更新的包

Question

我有一个简单的 Ansible playbook，用于在我管理的所有服务器上运行更新：

- hosts: ubuntu
  tasks:
  - name: install all updates
    apt:
      upgrade: dist
      update_cache: yes
      autoremove: yes
      autoclean: yes
- hosts: centos
  tasks:
  - name: install all updates
    yum:
      name: '*'
      update_cache: yes
      state: latest
# use debug to show the output
    register: result
  - name: Show Output
    debug: msg="{{ result.stdout_lines }}"

有什么办法可以让 Ansible 向我展示在这个过程中哪些包得到了更新？apt和yum模块都没有为此提供选项。

目前使用的 Ansible 版本是 2.4。

从 HBruijn 的评论开始，我扩展了我的剧本以显示包管理日志的结果：

---

- hosts: ubuntu
  tasks:
  - name: install all updates
    apt:
      upgrade: dist
      update_cache: yes
      autoremove: yes
      autoclean: yes
    register: result
  - name: List installed and updated packages
    shell: grep -E "^$(date +%Y-%m-%d).+ (install|upgrade) " /var/log/dpkg.log |cut -d " " -f 3-5
    register: result
  - name: Show Output
    debug: msg="{{ result.stdout_lines }}"
- hosts: centos
  tasks:
  - name: install all updates
    yum:
      name: '*'
      update_cache: yes
      state: latest
  - name: List updated packages
    shell: rpm -qa --last | grep "$(date +%a\ %d\ %b\ %Y)" |cut -f 1 -d " "
    register: result
    args:
      warn: no
  - name: Updates packages
    debug: msg="{{ result.stdout_lines }}"

结果输出：

ok: [ubuntu-host] => {
    "msg": [
        "upgrade python3-problem-report:all 2.14.1-0ubuntu3.25",
        "upgrade python3-apport:all 2.14.1-0ubuntu3.25",
        "upgrade apport:all 2.14.1-0ubuntu3.25",
        "upgrade firefox:i386 56.0+build6-0ubuntu0.14.04.2",
        "upgrade python-problem-report:all 2.14.1-0ubuntu3.25",
        "upgrade python-apport:all 2.14.1-0ubuntu3.25",
        "upgrade xul-ext-ubufox:all 3.4-0ubuntu0.14.04.1"
    ]
}

ok: [centos-host] => {
    "msg": [
        "kernel-headers-2.6.32-696.16.1.el6.x86_64",
        "lvm2-2.02.143-12.el6_9.1.x86_64",
        "device-mapper-multipath-0.4.9-100.el6_9.1.x86_64",
        "kernel-2.6.32-696.16.1.el6.x86_64",
        "kernel-firmware-2.6.32-696.16.1.el6.noarch",
        "lvm2-libs-2.02.143-12.el6_9.1.x86_64",
        "kpartx-0.4.9-100.el6_9.1.x86_64",
        "device-mapper-multipath-libs-0.4.9-100.el6_9.1.x86_64",
        "device-mapper-event-libs-1.02.117-12.el6_9.1.x86_64",
        "device-mapper-event-1.02.117-12.el6_9.1.x86_64",
        "device-mapper-1.02.117-12.el6_9.1.x86_64",
        "util-linux-ng-2.17.2-12.28.el6_9.1.x86_64",
        "device-mapper-libs-1.02.117-12.el6_9.1.x86_64",
        "libblkid-2.17.2-12.28.el6_9.1.x86_64",
        "libuuid-2.17.2-12.28.el6_9.1.x86_64"
    ]
}

这是一个巨大的改进，但我仍然希望有人有更好的解决方案。
