Yaml Ansible AnsibleUndefinedVariable无属性

我有以下文件vars/main.yml

testconfig:
 - {hostname: router123, example: no ip cef}

cisco_891_l2interfaces:
 - FastEthernet0
 - FastEthernet1
 - FastEthernet2
 - FastEthernet3
 - FastEthernet4
 - FastEthernet5
 - FastEthernet6
 - FastEthernet7

euvar:
 - {dc1: "1.1.1.1", dc2: "1.2.2.2"}

任务main.yml

- name: Generate configuration files for DMVPN router
  template: src=router.j2 dest=/lib/python2.7/site-packages/ansible/RTR-TEMPLATE/bla/bla.txt
  with_items: testconfig

路由器.j2

{{item.example}}

!
boot-start-marker
boot-end-marker
!

{{euvar.dc1}}

    TASK: [router | Generate configuration files for DMVPN router] ****************
fatal: [localhost] => {'msg': "AnsibleUndefinedVariable: One or more undefined variables: 'list object' has no attribute 'dc1'", 'failed': True}
fatal: [localhost] => {'msg': 'One or more items failed.', 'failed': True, 'changed': False, 'results': [{'msg': "AnsibleUndefinedVariable: One or more undefined variables: 'list object' has no attribute 'dc1'", 'failed': True}]}

FATAL: all hosts have already failed -- aborting

这给了我一个错误，我不确定如何从router.j2引用euvar.dc1

    TASK: [router | Generate configuration files for DMVPN router] ****************
fatal: [localhost] => {'msg': "AnsibleUndefinedVariable: One or more undefined variables: 'list object' has no attribute 'dc1'", 'failed': True}
fatal: [localhost] => {'msg': 'One or more items failed.', 'failed': True, 'changed': False, 'results': [{'msg': "AnsibleUndefinedVariable: One or more undefined variables: 'list object' has no attribute 'dc1'", 'failed': True}]}

FATAL: all hosts have already failed -- aborting

您将

euvar

定义为一个目录列表。但您正试图直接访问第一个列表项。从我的感觉来看，你只是想要一个这样的口述：

euvar: {dc1: "1.1.1.1", dc2: "1.2.2.2"}

或者对于那些喜欢可读性的人：

euvar:
  dc1: 1.1.1.1
  dc2: 1.2.2.2

然后您将能够以

{{euvar.dc1}}

的身份访问它

如果您真的想定义一个dict列表，那么您可以像这样访问它@ᴳᵁᴵᴰᴼ 已经对以下问题发表了评论：

{{euvar[0].dc1}

请同时查看Ansibles和。变量的名称表明您正在使用Ansibles。

是否也应该循环使用

euvar

（如

testconfig

）？还是只需要选择第一行的值？（在后一种情况下，它是

{{euvar[0].dc1}}

）基本上我有特定于区域的IP地址。我想在region=EU时从dc1 euvar获取值，在region=us时使用usvar dc1。
