templates - 如何在jinja2中追加到 list

Question

以下是我编写的用于ansible的jinja2模板。

{% set port = 1234 %}
{% set server_ip = [] %}
{% for ip in host_ip  %}
{% do server_ip.append({{ ip }}:{{ port }}) %}
{% endfor %}
{% server_ip|join(', ') %}

以下是我想要的输出：

devices = 192.168.56.14:1234,192.168.56.13:1234,192.168.56.10:1234

但是当我运行ansible剧本时，它抛出如下错误：

"AnsibleError: teme templating string: Encountered unknown tag 'do'. Jinja was looking for th: 'endfor' or 'else'

任何帮助，将不胜感激..

Answer 1

试试下面的代码：

{% set port = '1234' %}
{% set server_ip = [] %}
{% for ip in host_ip  %}
{{ server_ip.append( ip+":"+port ) }}
{% endfor %}
{{ server_ip|join(',') }}

你会得到：


192.168.56.14:1234,192.168.56.13:1234,192.168.56.10:1234
