关于Ansible的问题

ansible

关于Ansible的问题,ansible,jinja2,Ansible,Jinja2,我已经开始接受责任培训。我有一个非常简单的用例：我正在尝试使用jinja模板生成html文件。在此处找到我的yml文件： --- - name: "Generate html file for each host" hosts: all connection: local gather_facts: yes vars: host_inventory: "localhost" inventory_dir: "/home/ansible/Ansible/ch02

我已经开始接受责任培训。
我有一个非常简单的用例：我正在尝试使用jinja模板生成html文件。
在此处找到我的yml文件：

---

- name: "Generate html file for each host"
  hosts: all
  connection: local
  gather_facts: yes
  vars:
    host_inventory: "localhost"
    inventory_dir: "/home/ansible/Ansible/ch02/var/www/html/inventory"
  tasks:
    - name: "Create template directory"
      file:
        path: "{{playbook_dir}}"
        owner: "ansible"
        group: "ansible"
        mode: "0755"
        state: "directory"
      delegate_to: "{{host_inventory}}"
    - name: "Html file generation"
      template:
        src: "host.html.j2"
        dest: "{{playbook_dir}}/{{inventory_hostname}}.html"
      delegate_to: "{{host_inventory}}"

在此处找到jinja文件：

<html>
  <head>
    <title> host {{inventory_hostname}} </title>
  </head>
  <body>
    <p> 
      This host is called {{inventory_hostname}} 
    </p>
    <p>
      Find below a list of IPv4 adresses :
    </p>
    <ul>
      {% for ip in ansible_all_ipv4_addresses %}
      <li> {{ip}} </li>
      {% endfor }
    </ul>
  </body>
</html>

由于

{{inventory\u hostname}}

魔术变量解释错误，执行似乎失败：

[DEPRECATION WARNING]: The TRANSFORM_INVALID_GROUP_CHARS settings is set to allow bad characters in group names by default, this
 will change, but still be user configurable on deprecation. This feature will be removed in version 2.10. Deprecation warnings
can be disabled by setting deprecation_warnings=False in ansible.cfg.
[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details

您看到的错误是：

AnsibleError:模板化字符串时出现模板错误：意外“}”

这通常表示模板中存在语法错误。在你的情况下，你有一个打字错误。查看

      {% for ip in ansible_all_ipv4_addresses %}
