如何根据set_facts将多个条件合并为一个条件

问题描述

在通过SO post中的一个ansible配方时，我发现将set_fact与不同的条件检查一起使用时很有趣。但是，我根据自己的方法在帖子中作了回答。不过，我仍然看到可以将类似条件的多个条件合并在一起，例如确定location resource group和vnet。>

下面是playbook和变量文件azure_vars.yml

播放

---
- name: create azure vm
  hosts: localhost
  connection: local
  tasks:
   -  include_vars: azure_vars.yml

   - set_fact:
      host: "{{ azure_vm_name.split('.') }}"

   - set_fact:
       domain: "{{ host.1 }}.{{ host.2 }}"

   - name: Domain
     debug:
      msg: "{{ domain }}"

   - set_fact:
      location: "{{ azure_location[0] }}"
     when: 'domain == azure_domain[0]'

   - set_fact:
      location: "{{ azure_location[1] }}"
     when: 'domain == azure_domain[1]'

   - set_fact:
      location: "{{ azure_location[2] }}"
     when: 'domain == azure_domain[2]'

   - name: Location
     debug:
      msg: "{{ location }}"

   - set_fact:
      res_group: "{{ azure_res_group[0] }}"
     when: 'domain == azure_domain[0]'

   - set_fact:
      res_group: "{{ azure_res_group[1] }}"
     when: 'domain == azure_domain[1]'

   - set_fact:
      res_group: "{{ azure_res_group[2] }}"
     when: 'domain == azure_domain[2]'

   - name: Resource Group
     debug:
      msg: "{{ res_group }}"

   - set_fact:
      vnet: "{{ azure_nprod_vnet }}"
     when: 'domain == azure_domain[0]'

   - set_fact:
      vnet: "{{ azure_prod03_vnet }}"
     when: 'domain == azure_domain[2]'

   - set_fact:
      vnet: "{{ azure_prod02_vnet }}"
     when: 'domain == azure_domain[1]'

   - name: Vnet
     debug:
      msg: "{{ vnet }}"

变量文件

此文件包含所有变量，这些变量将是playbook的一部分，并在任务部分作为include_vars导入。

$ cat azure_vars.yml
---
azure_nprod_vnet: "/subscriptions/XXXXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXXX/resourceGroups/rg001/providers/Microsoft.Network/virtualNetworks/vnet"
azure_prod02_vnet: "/subscriptions/XXXXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXXX/resourceGroups/rg003/providers/Microsoft.Network/virtualNetworks/vnet"
azure_prod03_vnet: "/subscriptions/XXXXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXXX/resourceGroups/rg002/providers/Microsoft.Network/virtualNetworks/vnet"

    
# Azure domain
azure_domains:
  - us-sea01
  - us-azrc2
  - eu-azrc1


# Resource group
azure_res_group:
  - rg001
  - rg002
  - rg003

# Azure locations
azure_location:
  - westus2
  - southcentralus
  - westeurope
...

期望将以下三项合并为一种条件：

   - set_fact:
      location: "{{ azure_location[0] }}"
     when: 'domain == azure_domain[0]'

   - set_fact:
      location: "{{ azure_location[1] }}"
     when: 'domain == azure_domain[1]'

   - set_fact:
      location: "{{ azure_location[2] }}"
     when: 'domain == azure_domain[2]'

可能类似于：

   - set_fact:
      location:
        - azure_location[0]
        - azure_location[1]
        - azure_location[2]
     when:
       - 'domain == azure_domain[0]
       - 'domain == azure_domain[1]
       - 'domain == azure_domain[2]
