【问题描述】：

老实说，我不确定我正在尝试做的事情是否在技术上被称为，但会尽力解释。

结束结果：

我想要一个与此类似的数据列表和/或 JSON：

"ansible_facts": {
        "fact_pcs_resource_status": [
            {
                "resource": "nfs-transfer01_18",
                "type": "(ocf::heartbeat:exportfs)",
                "state": "Started",
                "target": "testserver07.local.net"
            },
            {
                "resource": "nfs-transfer03_18",
                "type": "(ocf::heartbeat:exportfs)",
                "state": "Started",
                "target": "testserver07.local.net"
            },
            {
                "resource": "nfs-transfer01_19",
                "type": "(ocf::heartbeat:exportfs)",
                "state": "Started",
                "target": "testserver07.local.net"
            }

我被困在哪里（解释）：

逻辑思维

- name: set_fact_pcs_status
  ansible.builtin.set_fact:
    fact_pcs_status: "{{ fact_pcs_status|default([]) + [ {'resource': item.0.name, 'type': item.1, 'state': item.2, 'target': item.3 } ] }}"
  with_together:
    - "{{ var_pcs_resources }}"
    - "{{ type }}"
    - "{{ state }}"
    - "{{ target }}"
  vars:
    regex_expression: "{{ var_pcs_resources.name }}\\s+(\\(.*\\)):\\s+(\\S*)\\s+(\\S*)\\s+(\\(.*\\)):\\s+(\\S*)\\s+(\\S*)"
    type: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression, '\\1') }}"
    state: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression, '\\2') }}"
    target: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression, '\\3') }}"

现在上面的方法不起作用，我迷路了。我相信我真正需要的是一个循环中的循环来完成我想要的'loop_control'但不确定。

所以在“思想”代码中：

从变量“var_pcs_resources”中提取资源名称
使用这个作为循环索引（因为应该只有这些资源在 PCS 上配置）
RegEx 通过 'reg_command_pcs_status.stdout' 找到 'type, 状态和目标”
循环的每次迭代都会改变 'regex_express' "{{ var_pcs_resources.name }}" 部分

我试图将其分解为不同的事实捕获/创建，但我无法超越需要将变量动态调用到 regex_expression 中的地步。

【解决方案1】：

好像有什么东西坏了：

在您的正则表达式中
在您的循环中带来的复杂性

使用regex_findall，您可以获得所有匹配项的列表，因此您无需拥有多个regex_findall。

结果列表实际上是一个包含所有匹配项的列表，然后对于每个匹配行，您使用正则表达式的捕获组捕获的片段。

所以，给定：

regex_expression: "{{ item.name }}\\s+(\\S+):\\s+(\\S+)\\s+(\\S+)"
matches: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression) }}"

在字符串上

nfsclst02-lvm      (ocf::heartbeat:LVM):   Started testserver07.local.net

matches.0.0 将是 (ocf::heartbeat:LVM)，所以，你的 type
matches.0.1 将是 Started，所以，你的 state
matches.0.2 将是 testserver07.local.net，所以，你的 target

现在，因为您每次搜索只有一个匹配项，您可以简化这一点并将flatten 列表列表，以结束

regex_expression: "{{ item.name }}\\s+(\\S+):\\s+(\\S+)\\s+(\\S+)"
matches: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression) | flatten }}"

这会将匹配简化为：

matches.0 将是 (ocf::heartbeat:LVM)，所以，你的 type
matches.1 将是 Started，所以，你的 state
matches.2 将是 testserver07.local.net，所以，你的 target

所以你的任务最终是：

- name: set_fact_pcs_status
  ansible.builtin.set_fact:
    fact_pcs_status: "{{ fact_pcs_status|default([]) + [ {'resource': item.name, 'type': matches.0, 'state': matches.1, 'target': matches.2 } ] }}"
  loop: "{{ var_pcs_resources }}"
  vars:
    regex_expression: "{{ item.name }}\\s+(\\S+):\\s+(\\S+)\\s+(\\S+)"
    matches: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression) | flatten }}"

鉴于剧本：

- hosts: all
  gather_facts: no

  tasks:
    - ansible.builtin.set_fact:
        fact_pcs_status: "{{ fact_pcs_status|default([]) + [ {'resource': item.name, 'type': matches.0, 'state': matches.1, 'target': matches.2 } ] }}"
      loop: "{{ var_pcs_resources }}"
      vars:
        regex_expression: "{{ item.name }}\\s+(\\S+):\\s+(\\S+)\\s+(\\S+)"
        matches: "{{ reg_command_pcs_status.stdout | regex_findall(regex_expression) | flatten }}"
        var_vcdc01_ip: foo
        var_nfsclst02_vip: bar
        var_vcdc02_ip: bar_ip
        var_vcdc03_ip: baz
        var_vcdc04_ip: qux
        var_vcdc05_ip: quux
        reg_command_pcs_status:

【讨论】：

@B.enoit.Be 这很好地澄清了这个问题并给了我基础。我最终得到了一个稍微不同的设置，但仍然需要这个来解决另一个问题。

【解决方案2】：

我最终创建了一个稍微不同的输出，我可以通过 JMES 轻松查询以查找任何状态。


    ## Build an array (fact) of only names of variable 'var_pcs_resources'
    - name: set_fact_pcs_resource_names
      ansible.builtin.set_fact:
        fact_pcs_resource_names: "{{ fact_pcs_resource_names | default([]) + [ {'name': item.name} ] }}"
        cacheable: yes
      loop: "{{ var_pcs_resources }}"
      run_once: True

    ## Build an array (fact) using 'fact_pcs_resource_name' as the variable
    - name: set_fact_pcs_resource_status
      ansible.builtin.set_fact:
        fact_pcs_resource_status: "{{ fact_pcs_resource_status | default([]) + [ {'name': item.name, 'type': type, 'state': state, 'target': target } ] }}"
