如何获取服务器名称列表并向每个名称附加资源 URI 和端口? [英] How can I take a list of server names and append a resource URI and port to each?

问题描述

我从 Ansible 清单中合并了两个列表:

I merged two lists from an Ansible inventory:

set_fact:
  fact1: "{{ groups['group1'] + groups[group2']|list }}

输出为:

fact1:
  - server01
  - server02
  - server03

有了上面的结果，我需要在前面附加https://，在每个元素的后面附加一个端口号.然后我需要将它转换为服务器配置的逗号分隔列表.

With the above results, I need to append https:// to the front, and a port number to the back of each element. Then I need to convert it to a comma delimited list for a server config.

在这个例子中我想要:https://server01:8000,https://server02:8000,https://server03:8000.

In this example I want: https://server01:8000,https://server02:8000,https://server03:8000.

我尝试使用连接:

set_fact:
  fact2: "{{ fact1|join(':8000,') }}"

部分工作但它使最后一个服务器没有端口.

which partly worked but it left the last server without a port.

我怎样才能实现我的目标?

How can I achieve my goal?

推荐答案

解决方案

set_fact:
  fact2: "{{ fact1 | map('regex_replace', '(.*)', 'https://\1:8000') | join(',') }}"

说明

1. map 过滤器适用过滤器(regex_replace)到列表的各个元素；

1. map filter applies a filter (regex_replace) to individual elements of the list;

regex_replace 过滤器(使用下面的正则表达式)为字符串添加prefix和suffix；

current_list | map('regex_replace', '(.*)', 'prefix\1suffix')

join 过滤器 转换输出中以逗号分隔的字符串的列表.

join filter converts the list to comma-delimited string in the output.

替代方案

另一种可能的解决方案(建立在您已经知道的基础上)是使用 Jinja2 直接用于目标字符串:

Another possible solution (builds on what you already know) would be to use Jinja2 to directly for the target string:

set_fact:
  fact2: "{{ 'https://' + fact1|join(':8000,https://') + ':8000' }}"
