Ansible set_fact 数组并从循环中填充它 [英] Ansible set_fact array and populate it from in loop

问题描述

我想创建一个数组并将数组IP_TO_DNS中的值插入到反向IP地址中.

I want to create an array and insert value from the the array IP_TO_DNS to reversed IP address.

这个想法是重构参数中给出的 IP 地址，以便稍后在我的代码中进行匹配.

The idea is to restructure the IP address given in the argument to be matchable later in my code.

代码

- name: create array reversed
  set_fact: reversed_ip=[]

- name: set convert ips from cli to matchable reversed ip
  set_fact: reversed_ip='{{ item | regex_replace('^(?P<first_range>\d{1,3})\.(?P<second_range>\d{1,3})\.(?P<third_range>\d{1,3})\.', 'named.\\g<third_range>.\\g<second_range>.\\g<first_range>')}}'
  with_items: '{{IP_TO_DNS}}'

- name: Match first block of results in path name
  debug: var=item
  with_items: '{{reversed_ip}}'

输出

TASK [dns : set convert ips from cli to matchable reversed ip] *****************
ok: [10.1.10.5] => (item=10.1.10.1)
ok: [10.1.10.5] => (item=10.1.10.2)
ok: [10.1.10.5] => (item=10.1.10.3)

TASK [dns : Match first block of results in path name] *************************
ok: [10.1.10.5] => (item=named.10.1.103) => {
    "item": "named.10.1.103"
}

看起来我的变量没有设置为数组，只填充了第一个值.

It look like my variable is not set as an array and only the first value is populate.

有什么想法吗?

推荐答案

您设置了 3 次相同的事实，但它被覆盖了.

You are setting the same fact three times and it gets overwritten.

您应该注册输出:

- name: set convert ips from cli to matchable reversed ip
  set_fact: reversed_ip='{{ item | regex_replace('^(?P<first_range>\d{1,3})\.(?P<second_range>\d{1,3})\.(?P<third_range>\d{1,3})\.', 'named.\\g<third_range>.\\g<second_range>.\\g<first_range>')}}'
  with_items: '{{IP_TO_DNS}}'
  register: reversed_ip_results_list

- name: Match first block of results in path name
  debug: var=item.ansible_facts.reversed_ip
  with_items: '{{reversed_ip_results_list.results}}'

或者如果你想要一个列表:

or if you want a list:

- debug: msg="{{ reversed_ip_results_list.results | map(attribute='ansible_facts.reversed_ip') | list }}"
