我想在 Jinja2 的 Ansible 上下文中包含另一个 Jinja2 模板 [英] I want to include another Jinja2 template in an Ansible context in Jinja2

问题描述

我有一个 Ansible playbook，它设置了很多变量.一个剧本有这个任务:

I have an Ansible playbook that sets a lot of variables. One the playbooks has this task:

- name: create config file 
  template:
    src: 'templates/main_config.j2'
    dest: "{{ tmp_dir }}/main_config.json"

模板 main_config.j2 写入在父 Ansible 剧本和任务中定义为变量的字符串.

The template main_config.j2 writes strings that are defined as variables in the parent Ansible playbooks and tasks.

我想包含另一个基于 Ansible 变量值的 Jinja2 模板.

I want to include another Jinja2 template based on a value of an Ansible variable.

{% include "./templates/configurations.j2" %}, 
{% include "./templates/security.j2" %},
{% include './templates/' + {{ job }} + '_steps.j2' %}

job 是在父剧本中设置的 Ansible 变量.

job is a Ansible variable set in a parent playbook.

这不起作用.可能是什么问题呢?

This is not working. What could be the problem?

推荐答案

您不需要打开 Jinja2 表达式 ({{ ... }}) 来引用内部变量语句 ({% ... %}).可以直接使用变量名:

You don't need to open a Jinja2 expression ({{ ... }}) to refer to a variable inside a statement ({% ... %}). You can use the variable name directly:

{% include './templates/' + job + '_steps.j2' %}
