如何从ansible playbook中的文件中读取所有行

Question

我有一个名为 packages.txt 的文件，其中包含软件包列表。我必须通过我的 ansible 文件 rpm.yml 阅读 package.txt 的每一行。这是我的代码

- hosts: myhost
  tasks:

     - name: RPM Filter
       theforeman.foreman.content_view_filter:
         username: "admin"
         password: "admin"
         server_url: "myhost"
         name: "rpm filter"
         organization: "myorg"
         content_view: "My content view"
         filter_type: "rpm"
         package_name: "{{ item }}"
         inclusion: True
       loop:
         - packages.txt

我的packages.txt包含这些

open-ssh
nginx
grafana
vim

如有任何帮助，我们将不胜感激

Answer 1

您将需要一个额外的任务来读取文件。最简单的方法是将 cat 文件和 register 放入变量中。然后这个变量可以用于下一个任务。

类似于：

    - name: get contents of package.txt
      command: "cat packages.txt"
      register: _packages

     - name: RPM Filter
       theforeman.foreman.content_view_filter:
         username: "admin"
         password: "admin"
         server_url: "myhost"
         name: "rpm filter"
         organization: "myorg"
         content_view: "My content view"
         filter_type: "rpm"
         package_name: "{{ item }}"
         inclusion: True
       loop: "{{ _packages.stdout_lines }}"

Answer 2

query 行插件。例如

    - debug:
        var: item
      loop: "{{ query('lines', 'cat packages.txt') }}"

给出（删节）

  item: open-ssh
  item: nginx
  item: grafana
  item: vim
