Question

我正在编写一本ansible playbook来自动安装一个软件。当我从网站下载tarball时：

software-package-release.tar.gz

当解开时，我留下目录

software-package-v2.15/

ansible有没有办法注册作为unarchive模块的一部分创建的目录？

我尝试了以下播放（我将nrpe-lkdsflkdjf文件放在那里，其中包含一个目录nrpe-2.15）

- name: Extract
  unarchive
    src:/tmp/nrpe-lkdsflkdjf
    dest: /tmp/
    copy: no
  register: tar_reg

- name: debug tar_reg
  debug: var=tar_reg

这是调试的输出：

    "tar_reg": {
        "changed": true, 
        "check_results": {
            "cmd": "/bin/gtar -C \"/tmp/\" --diff -f \"/tmp/nrpe-lkdsjflkdsjf\"",

Answer 1

unarchive module可以选择列出文件 - import pandas as pd DF1 = pd.DataFrame({'name': ['abc in first line of text', 'abc of second line of text', 'def on third line of text'], 'other': [10, 20, 30]}) DF2 = DF1[DF1.name.str.startswith('abc')] DF2['name'] = [x.split('abc')[1][4:].title() for x in DF2['name']] print(DF2)。输出可以注册，通常数组中的第一个值是目录名。

以下对我有用：

list_files

- name: Extract files unarchive: src: /tmp/my_archive.tar.gz dest: /mydir remote_src: yes list_files: yes register: archive_contents将包含您的顶级目录。

Answer 2

更新：请参阅@ vinayak-thatte的answer以获取正确答案。

Unarchive模块不知道存档中的内容 - 它只是将所有存档内容放入dest文件夹。

如果你事先知道存档中有一个或哪个文件夹，你可以做这样的测试：

- name: Get dir 1 - fast - when you are sure that there is one and only one subfolder
  shell: tar tf file.tgz | head -1 | sed -e 's/\/.*//'
  changed_when: false
  register: tar_test

- debug: 'msg="Subfolder: {{tar_test.stdout}}"'

- name: Get dir 2 - slow - when you dont sure
  shell: tar tf file.tgz | sed -e 's/\/.*//' | sort | uniq
  changed_when: false
  register: tar_test

- debug: 'msg="Subfolder: {{tar_test.stdout}}"'
  when: tar_test.stdout_lines | count == 1

- debug: msg="No subfolder!"
  when: tar_test.stdout_lines | count > 1

第一种方法比第二种方法快，但它只检查一行存档文件列表 - 所以你必须确保里面只有一个子文件夹。
第二种方法检查存档中的所有路径并在存档“root”中收集不同的名称 - 因此，如果只有一个匹配（count == 1），则很可能是子文件夹（或存档中的单个文件： - /），否则档案“root”中有很多条目。

如何判断ansible的unarchive模块创建了哪个目录？
