Ansible |在循环内使用变量进行查找

Question

我想根据

ansible_distribution

变量获取特定的字典并在

with_items

中使用它，但我无法使用查找来检索字典内容。我尝试这样的事情：

- hosts: all
  gather_facts: true
  become: yes
  vars:
    distributions:
      Centos: 
        repos:
          - repo_name: 'repo1'
            baseurl: 'url1' 
            file: 'file1'
            gpgkey: 'gpgkey1'
      Rocky:
        repos:
          - repo_name: 'repo2'
            baseurl: 'url2' 
            file: 'file2
            gpgkey: 'gpgkey2'
  
  tasks:   
    - name: Add Yum Repo
      become: yes
      yum_repository:
        name: "{{ item.repo_name }}"
        description: EpelUpdate
        baseurl: "{{ item.baseurl }}"
        file: " {{ item.file }}"
        gpgcheck: 0
        gpgkey: "{{ item.gpgkey }}"
      with_items:
        - "{{ lookup(vars, distributions.{{ ansible_distribution }}.repos) }}" #<-- this line is wrong

我收到错误：

"msg": "template error while templating string: expected name or number. String: {{ lookup(vars, distributions.{{ ansible_distribution }}.repos) }}" 

Answer 1

我找到了解决方案。简单

"{{ distributions[ansible_distribution].repos }}"

就够了
