jinja2文件

  1. modules:
  2. {% for item in ipmi_nodes %}
  3.   {{ item.ip }} :
  4.       user: "{{ item.user | default("root") }}"
  5.       pass: "{{ item.pass | default("99cloud") }}"
  6.       driver: "{{ item.driver | default("LAN_2_0") }}"
  7.       privilege: "{{ item.privilege | default("admin") }}"
  8.       collectors: {{ item.collectors | default(["bmc", "ipmi", "chassis", "dcmi"]) }}
  9. {% endfor %}

yaml文件

  1. ---
  2. ipmi_nodes:
  3.   - ip: 172.16.140.202
  5.   - ip: 172.16.140.203
  7.   - ip: 192.168.2.105
  8.     pass: "Huawei12$#"
  9.     collectors: "['dcmi', 'ipmi']"

yaml文件作为数据源输入，jinja按照jinja2文件格式渲染数据，生成下面的文件

  2. modules:
  3.   172.16.140.202 :
  4.       user: "root"
  5.       pass: "99cloud"
  6.       driver: "LAN_2_0"
  7.       privilege: "admin"
  8.       collectors: ['bmc', 'ipmi', 'chassis', 'dcmi']
  9.   172.16.140.203 :
  10.       user: "root"
  11.       pass: "99cloud"
  12.       driver: "LAN_2_0"
  13.       privilege: "admin"
  14.       collectors: ['bmc', 'ipmi', 'chassis', 'dcmi']
  15.   192.168.2.105 :
  16.       user: "root"
  17.       pass: "Huawei12$#"
  18.       driver: "LAN_2_0"
  19.       privilege: "admin"
  20.       collectors: ['dcmi', 'ipmi']

对于collectors的渲染，需要数据格式为字符串，如 "strings" ，然后将 ['dcmi', 'ipmi'] 以jinja2文件对应的格式 collectors: {{ item.collectors | default(["bmc", "ipmi", "chassis", "dcmi"]) 渲染成 collectors: ['dcmi', 'ipmi']

以下格式如何渲染呢？

  1.  - ip: 192.168.2.105
  2.     pass: "Huawei12$#"
  3.     collectors:
  4.       - ipmi
  5.       - dcmi

包含unicode字符串默认渲染带 u

yaml文件

  1. source_index: [ifIndex]

配置一

jinja2文件

  1. source_index: {{ item }}

output:

  1. source_index: [u'ifIndex']

配置二

jinja2文件

  1. source_index: [{{ item | list | join('\',\'') }}

output：

  1. source_index: [ifIndex]
