不可接受的apt-获取安装输出

Question

我正在使用带有ansible游戏手册的流浪汉在一个ubuntu映像上自动安装一组程序。有一个程序未能安装在流浪VM上。在我的Vagrant文件中

config.vm.provision :ansible do |ansible|
  ansible.verbose = "vvv"
  ansible.playbook = "provisioning/playbook.yml"
end

但是详细的输出不包括apt-get输出。我的playbook.yml看起来就像

---
- hosts: all
  sudo: true
  tasks:
    - name: get vi
      apt: state=latest name=vim  

我如何才能在VM上看到单个(或全部)apt-get install的控制台输出，因为ansible会以格式输出每个安装。

TASK: [Install vim] *********************************************************** 
failed: [default] => {"failed": true}
...

Answer 1

您可以将apt模块执行的输出注册到变量中，然后打印出来。

- hosts: localhost
  sudo: true
  tasks:
    - name: get vi
      apt: state=latest name=vim
      register: aptout

    # show the content of aptout var
    - debug: var=aptout

Answer 2

复制stdout of apt

下面是如何复制stdout of apt…

---
- name: 'apt: update & upgrade'
  apt:
    update_cache: yes
    cache_valid_time: 3600
    upgrade: safe
  register: apt
- debug: msg={{ apt.stdout.split('\n')[:-1] }}

…感谢.split('\n')，并使用[:-1]省略最后一个空字符串，所有这些当然都是Python操作。

"msg": [
    "Reading package lists...", 
    "Building dependency tree...", 
    "Reading state information...", 
    "Reading extended state information...", 
    "Initializing package states...", 
    "Building tag database...", 
    "No packages will be installed, upgraded, or removed.", 
    "0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.", 
    "Need to get 0 B of archives. After unpacking 0 B will be used.", 
    "Reading package lists...", 
    "Building dependency tree...", 
    "Reading state information...", 
    "Reading extended state information...", 
    "Initializing package states...", 
    "Building tag database..."
]

Answer 3

在我目前使用的ansible版本中，ansible-playbook -v似乎足以获得apt输出。诚然，我没有测试过失败。输出以JSON的形式出现，这使其读起来有点困难(因为另一个答案是工作的)。

我测试的Ansible版本是2.3.2.0。
