如何在ansible中通过掩码选择包名称？

  • 772

我需要获取名称以dotnet.

该方案有效：

- debug:
    msg: "{{ ansible_facts.packages['dotnet-runtime-3.1'] }}"

而这个不见了：

- debug:
    msg: "{{ ansible_facts.packages['dotnet*'] }}"

"{{ ansible_facts.packages | regex_findall('^dotnet.*') }}"由于某种原因，它也不起作用。

    有趣的点出现了。问题既解决了又没有同时解决。

    package_facts

    因此，package_facts模块仅显示有关已安装软件包的信息。那些可用的——他忽略了。这结束了避免使用aptitude searchand aptitude versions。但是，可以像这样提取有关已安装软件包的信息（非常感谢一位知道如何阅读文档的同事，不像我）。

    我将展示firefox：

    - package_facts:

- name: Get installed soft
  vars:
    my_json_query: keys(packages)[?contains(@, 'firefox')]
  set_fact:
    needing_package: "{{ ansible_facts | json_query(my_json_query) }}"

    ok: [test-vm.local] => {
    "ansible_facts": {
        "needing_package": [
            "firefox", 
            "firefox-locale-ru"
        ]
    }, 
    "changed": false
}

    掉了2个包裹。虽然它aptitude search firefox | wc -l回来了218

    解决特定问题

    Debian/Ubuntu

    除了 pull 之外，apt-cache我没有找到任何其他选项，因此：

    我们向缓存询问哪些带有掩码dotnet-runtime-*的数据包可供我们使用，拉出包含单词Package:and的行Version:，并形成 magic sed+ tr...

    apt-cache show dotnet-runtime-* | grep -E -i '(Package:|Version:)' | tr '\n' ' ' | sed 's| Package|\nPackage|g' | grep -v -i deps

    ...在撰写本文时，一片厚重的叶子看起来像这样：

    进一步 - 简单地说。我们拉取regex_search并且split已经从 ansible 下得到了这个（根据条件，我们需要找到包含版本的包的名称3.1.6）：

    vars:
  dotnet_current_version: 3.1.6

    - name: Find .NET versions on Debian\Ubuntu over shell
  when:
    - ansible_os_family == 'Debian'
    - ansible_pkg_mgr == 'apt'
  environment:
    LANG: C
    LC_ALL: C
  shell: apt-cache show dotnet-{{ dotnet_default_component }}-* | grep -E -i '(Package:|Version:)' | tr '\n' ' ' | sed 's| Package|\nPackage|g' | grep -v -i deps
  register: dotnet_current_version_list
  changed_when: dotnet_current_version_list.rc != 0

- name: Get current .NET version 4 install over shell
  when:
    - ansible_os_family == 'Debian'
    - ansible_pkg_mgr == 'apt'
  block:
    - set_fact:
        # https://stackoverflow.com/a/55047177/5430535
        dotnet_package_and_version_in_on_line_fact: "{{ dotnet_current_version_list.stdout | regex_search('.*' + dotnet_current_version + '.*') }}"
    - set_fact:
        dotnet_current_packagename_fact: "{{ dotnet_package_and_version_in_on_line_fact.split(' ')[1] }}"
    - set_fact:
        dotnet_current_version_fact: "{{ dotnet_package_and_version_in_on_line_fact.split(' ')[3] }}"

    输出将是这样的：

    ok: [test-vm.local] => {
    "ansible_facts": {
        "dotnet_package_and_version_in_on_line_fact": "Package: dotnet-runtime-3.1 Version: 3.1.6-1"
    }, 
    "changed": false
}

ok: [test-vm.local] => {
    "ansible_facts": {
        "dotnet_current_packagename_fact": "dotnet-runtime-3.1"
    }, 
    "changed": false
}

ok: [test-vm.local] => {
    "ansible_facts": {
        "dotnet_current_version_fact": "3.1.6-1"
    }, 
    "changed": false
}

    那些。现在你可以像这样安装dotnet它：

    - name: Install dotnet 4 Debian\Ubuntu
  when:
    - ansible_os_family == 'Debian'
    - ansible_pkg_mgr == 'apt'
  become: yes
  apt:
    name:
      - '{{ dotnet_current_packagename_fact }}={{ dotnet_current_version_fact }}'
    state: present
    install_recommends: yes
    force: yes

    附言ansible 2.9.11, python version = 2.7.12 (default, Jul 21 2020, 15:19:50) [GCC 5.4.0 20160609], ubuntu 16.04.6
