从不可否认的事实中删除双引号

Question

有一个json输出，我正试图解析它。我将输出注册到名为instance_ip的变量中。

以下是json输出：

目标是获取私有ip地址并附加端口号。

通过下面的任务，我得到了具有节点ip地址["10.x.x.x"]的列表

  - name: Getting EC2 instance ip address
    set_fact:
      instance_ip: "{{ logstash_instance | json_query('instances[*].network_interfaces[*].private_ip_address') | flatten }}"

在剧中的下一个任务中，我试图附加端口号，但我一直在得到

"'10.x.x.x:5044'“

  - name: Get everything between quotes and append port 5044
    set_fact:
      logstash_hosts: "{{ instance_ip | map('regex_replace', '^(.*)$', '\\1:5044') | list }}"

下面是模板输出：

# ------------------------------ Logstash Output -------------------------------
output.logstash:
  hosts: "['10.x.x.x:5044']"

我需要去掉双引号，并将干净的变量'10.x.x.x:5044‘传递给我的模板文件。

Answer 1

您可以尝试创建一个新的list变量，并将端口号附加到每个元素，使用以下方法：

  - set_fact:
      logstash_hosts: "{{ logstash_hosts|default([]) + [ item ~ ':5044' ] }}"
    with_items: "{{ instance_ip }}"

然后在模板中：

output.logstash:
  hosts: {{ logstash_hosts|to_yaml }}

另外，由于Logstash配置是YAML格式的文件，所以使用YAML列表语法并直接使用instance_ip变量(并避免使用set_fact)。然后模板将如下所示：

output.logstash:
  hosts:
{% for ip in instance_ip %}
  - {{ ip }}:5044
{% endfor %}
