Ansible，jinja2

  • 772

告诉我，我无法理解。为了测试，我赶紧勾勒，体验0..j2文件：

{% for group in groups['all'] %}
Host {{ group }}
User {{ ansible_user }}
{% endfor %}

主机文件：

[test1]
localhost1 ansible_host=localhost ansible_host_ip=127.0.0.1 ansible_user=arch1 ansible_connection=local
localhost2 ansible_host=localhost ansible_host_ip=127.0.0.2 ansible_user=test ansible_connection=local
localhost3 ansible_host=localhost ansible_host_ip=127.0.0.3 ansible_user=test ansible_connection=local
[test2]
localhost4 ansible_host=localhost ansible_host_ip=127.0.0.4 ansible_user=root1 ansible_connection=local

.yml 文件：

---
- name: Test SSH create
  hosts: all
  tasks:
    - name: Update Test SSH Jinja2
      template:
        src: /etc/ansible/temlates/ssh_test.j2
        dest: /etc/ansible/test

并输出：

Host localhost1
User test
Host localhost2
User test
Host localhost3
User test
Host localhost4
User test

为什么 ansible_user 总是一样的？他为什么不把它们一一放下？据我了解，这是因为 ansible_user 变量取自创建配置的主机。如何在不使用模块的情况下解决此问题？

    这就是我所需要的，如何指定变量并不明显。

    {% for group in groups['all'] %}    
Host {{ hostvars[group]['inventory_hostname'] }}
         HostName {{ hostvars[group]['inventory_hostname'] }}
         User {{ hostvars[group]['ansible_user'] }}
{% endfor %}
