根据Ansible / jinja2

Question

如何根据变量或事实过滤ansible列表？假设我有一个列表，其中列出了我想要的软件包和名称片段。

vars:
  package_urls: ['http...windows.exe', 'http...linux.rpm', 'http...babbage.steam']
  package_name: 'linux'

tasks:
- set_fact:
    selected_url: "{{ package_urls | select( 'match', '.*' + package_name + '.*') |list| first}}"

- debug:
    msg: "Select for {{ package_name }} is {{ selected_url }}"

这会产生所需的输出，但是肯定看起来很麻烦

Select for linux is http...linux.rpm
