如何使用动态变量查询ansible字典

Question

如何使用动态变量查询 Ansible 字典？ 我想用ansible从dell的idrac读取序列号，然后根据序列号设置地址。 我的源代码：

---
- hosts: all
  name: set iDRAC Ipaddr
  gather_facts: False
  vars:
    svctag_test: xxx30S2
    network_configs:
     xxx30S2:
       ip: 192.168.192.86

  tasks:

    - name: get dell server service-tag
      raw: racadm getsvctag
      register: svctag

    - name: show svctag
      debug: 
      msg="{{ svctag }}"      
     
    - name: show network 
      debug: 
        msg="{{ network_configs[svctag_test].ip }}"
    - name: set idrac ip svctag to vars
      set_fact:
        SVCTAG: "{{ svctag.stdout_lines }}" 
    - name: show SVCTAG
      debug: 
        msg="{{ SVCTAG }}"   
         
    - name: show network 2
      debug: 
         msg="{{ network_configs[SVCTAG].ip }}"
         #msg="{{ network_configs[SVCTAG] }}"   
         #msg="{{ hostvars[inventory_hostname][network_configs][SVCTAG] }}"
    
      #msg="{{ lookup('vars', network_configs )[SVCTAG]}}" 
     - name: set dell server idrac ip form service-tag
       raw: racadm config -g cfgLanNetworking -o cfgNicIpAddress "{{ network_configs[SVCTAG].ip }}"

- name: set idrac ip svctag to vars
  set_fact:
    SVCTAG: "{{ svctag.stdout_lines }}"

svctag.stdout_lines 是一个列表，而不是一个字符串。 尝试：

- name: set idrac ip svctag to vars
  set_fact:
    SVCTAG: "{{ svctag.stdout_lines[0] }}"
