用于查找和替换嵌套键值的剧本任务

Question

ip_details.yaml

---
ip1:
  image:
    name: <ip input> # ip address 1 

ip2:
  config:
    range: 192.0.0.0
  image:
    name: <ip input> # ip address 2
  id:
    username:  # ip username
    password:  # ip Password

fetch_value.yml

ip1_image_name: 192.0.0.1
ip2_image_name: 192.0.0.2
ip_username: user@123
ip_password: pass@123

任务是编写一个新的 update_ip.yml 任务，用于查找 ip_details.yaml 文件路径和 replacing/updating ip 输入以及 id 用户名和密码。

我试过了：

update_ip.yml

  - lineinfile:
        path: values.yml
        regexp: "{{ item.regexp }}"
        line: "{{ item.line }}"
        backrefs: true
      loop:
        - {regexp: '^(\s*)ip1.image.name: <user ip>(.*)$', line: 'name: {{ ip1_image_name }}'}
        - {regexp: '^(\s*)ip2.image.name: <user ip>(.*)$', line: 'name: {{ ip2_image_name }}'}
        - {regexp: '^(\s*)ip2.id.username:\s+.*?(\s+#.*)$', line: 'username: {{ ip_username }}'}
        - {regexp: '^(\s*)ip2.id.password:\s+.*?(\s+#.*)$', line: 'password: {{ ip_password }}'}

最终预期：ip_details.yml

ip1:
  image:
    name: 192.0.0.1 # ip address 1 

ip2:
  config:
    range: 192.0.0.0
  image:
    name: 192.0.0.2 # ip address 2
  id:
    username: user@123 # ip username
    password: pass@123 # ip Password

我建议您使用 template 模块：

在文件夹 templates 中创建您的模板文件 ip_details.j2（与您的剧本相同级别）

 ---
 ip1:
   image:
     name: {{ ip1_image_name }} # ip address 1 

 ip2:
   config:
     range: 192.0.0.0
   image:
     name: {{ ip2_image_name }} # ip address 2
   id:
     username:  {{ ip_username }} # ip username
     password:  {{ ip_password  }} # ip Password

创建剧本：

     - name: testplaybook jinja2
       hosts: localhost
       gather_facts: no
       vars:
         ip1_image_name: 192.0.0.1
         ip2_image_name: 192.0.0.2
         ip_username: user@123
         ip_password: pass@123

       tasks:
         - name: template
           template:
             src: ip_details.j2
             dest: ip_details.yml

结果 ip_details.yml:

 ---
 ip1:
   image:
     name: 192.0.0.1 # ip address 1 

 ip2:
   config:
     range: 192.0.0.0
   image:
     name: 192.0.0.2 # ip address 2
   id:
     username:  user@123 # ip username
     password:  pass@123 # ip Password
