如何使用ansible中的jinja2模板将字典转换为csv？

Question

我需要将自定义输出变量转换为字典，然后使用jinja2模板生成csv文件。

下面是代码

- name: Executing the cmd (multipath -ll | grep dm- | awk -F' dm' '{print $1}') to get the device name
   shell: multipath -ll | grep dm- | awk -F' dm' '{print $1}' | awk -F ' ' '{print $1}'
   register: multipath_device_name  
      
- name: Executing the cmd (multipath -ll | grep -E status='(active|inactive)' | awk -F ' ' '{print $5}' | cut -c 8-16) to get the device active or inactive 
  shell: multipath -ll | grep -E status='(active|inactive)' | awk -F ' ' '{print $5}' | cut -c 8-16
  register: multipath_device_status
                  
- name: Executing the cmd (multipath -ll | grep dm- | awk -F' dm' '{print $1}' | awk -F ' ' '{print $2}' | cut -d "(" -f2 | cut -d ")" -f1) to get the device active or inactive 
  shell: multipath -ll | grep dm- | awk -F' dm' '{print $1}' | awk -F ' ' '{print $2}' | cut -d "(" -f2 | cut -d ")" -f1
  register: multipath_device_id

- set_fact:
        multipath_devices:
          device_name: "{{ multipath_device_name.stdout_lines }}"
          device_id: "{{ multipath_device_id.stdout_lines }}"
          device_id_status: "{{ multipath_device_status.stdout_lines  }}"
          server_name: "{{ ansible_hostname }}"
          server_ip: "{{ ansible_default_ipv4.address }}"
- debug:
    msg: "{{ multipath_devices }}"

我得到了上述变量"multipath_devices“的以下输出

"msg": {
        "device_id": [
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx2",
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx3",
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx4",
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx5",
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6",
            "3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7",
            
        ],
        "device_id_status": [
            "active",
            "active",
            "active",
            "active",
            "active",
            "active"
            
        ],
        "device_name": [
            "name1",
            "name2",
            "name3",
            "name4",
            "name5",
            "name6"
        ],
        "server_ip": "192.168.56.120",
        "server_name": "node-01"

我尝试使用下面的jinja2模板将该变量转换为csv，但它没有给出我所需要的确切输出。请帮我用csv把这件事做完

{% for key, value in multipath_devices.items() %}
    {{key}}
    {{value}}
{% endfor %}

我需要CSV文件输出，如下所示

"device_name","device_id","device_id_status","server_name","server_ip"
name1, 3xxxxxxx3, active, server1, 192.168.56.201

下面是命令输出

name1 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx2)
name2 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx3)
name3 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx4)
name4 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx5)
name5 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6)
name6 (3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7)

在“文件”文件夹中创建一个csv.j2文件：(您在与您的剧本相同的位置创建文件夹文件)

{{ multipath_devices.keys()|list }}
{% for i in range(0, (maxnb|max|int)) %}
{%- for k in multipath_devices -%}
{{multipath_devices[k][i] if multipath_devices[k][i] is defined else multipath_devices[k][0]}}{{'' if loop.last else ', '}} 
{%- endfor -%}
{{'\n'}}
{%- endfor %}
{%- endfor %}

如果你这样写你的任务：

• set_fact: multipath_devices: device_name："{{ multipath_device_name.stdout_lines }}“device_id："{{ multipath_device_id.stdout_lines }”device_id_status：“{ multipath_device_status.stdout_lines }”server_name："{{ ansible_hostname }}“{{ }}"

server_ip：{ ansible_default_ipv4.address

(我模拟你的结果)

- name: "tips1"
  hosts: localhost
  vars:
    multipath_devices:
      device_name:
          - name1
          - name2
          - name3
          - name4
          - name5
          - name6
      device_id:
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx2
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx3
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx4
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx5
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6
          - 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7
      device_id_status:
          - active
          - active
          - active
          - active
          - active
          - active
      server_name: [node-01]          
      server_ip: [192.168.56.120]
  
  tasks:
    - name: trap max length of all lists
      set_fact:
        maxnb: "{{ maxnb | d([]) + [item.1|length]}}"
      loop: "{{multipath_devices.items()}}"
  
    - name: create csv
      template:
        src: csv.j2 
        dest: result.csv

Result.csv的结果：

device_name, device_id, device_id_status, server_name, server_ip
name1, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx2, active, node-01, 192.168.56.120
name2, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx3, active, node-01, 192.168.56.120
name3, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx4, active, node-01, 192.168.56.120
name4, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx5, active, node-01, 192.168.56.120
name5, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6, active, node-01, 192.168.56.120
name6, 3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx7, active, node-01, 192.168.56.120
