ansible正确的方法来分割扩展变量并创建新变量以在其他任务中使用？

问题描述 投票：0回答：1

运行 ansible 2.10.17

当我尝试扮演一个角色时，我不断得到

% Invalid input detected at '^' marker.
。 这是我的代码。请注意，“filter”、“trust”和“untrust”作为额外变量通过 
-e
传入。

-- name: Include vars
  include_vars:
    file: ../../../settings.yaml
    name: settings

- name: Extract tags from trust + untrust variables
  set_fact:
    trust_tag_filter: "{ {{ trust }}.split(':')[0] }"
    untrust_tag_filter: "{ {{ untrust }}.split(':')[0] }"

- name: Routers configuration, filter "{{ filter }}", with trust tag filter "{{ trust_tag_filter }}", and untrust tag filter "{{ untrust_tag_filter }}"
  iosxr_command:
    commands:
    - show run formal object-group network ipv4 | u egrep {{ filter }}
    - show run ipv4 access-list acl_trust_in | u egrep {{ filter }}
    - show run formal interface | u egrep "BVI{{ trust_tag_filter }}"
    - show run formal interface | u egrep "BVI{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether21.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether21.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether22.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether22.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether23.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether23.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether24.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether24.{{ untrust_tag_filter }}"
    - show run l2vpn bridge group TRUST bridge-domain "VLAN{{ trust_tag_filter }}"
    - show run l2vpn bridge group UNTRUST bridge-domain "VLAN{{ untrust_tag_filter }}"
    - show run router static address-family ipv4 unicast | utility egrep 'router\ static|family|{{settings.lan_subnet_prefix}}{{filter}}|10.30.{{filter}}'
    - show evpn evi | u egrep 'VPN-ID|{{ trust_tag_filter }}|{{ untrust_tag_filter }}'

但是当我运行它时，我不断收到此错误

为什么？我是否没有正确定义变量？

python variables split ansible cisco

想通了。两个问题。

  1. 我没有正确分裂。正确的方法是在变量内部进行拆分
trust_tag_filter: "{{ trust.split(':')[0] }}"
untrust_tag_filter: "{{ untrust.split(':')[0] }}"
  1. 我正在查询带双引号的 VLAN，必须将其删除。
- show run l2vpn bridge group TRUST bridge-domain VLAN{{ trust_tag_filter }}
- show run l2vpn bridge group UNTRUST bridge-domain VLAN{{ untrust_tag_filter }}

调整后的代码如下：

-- name: Include vars
  include_vars:
    file: ../../../settings.yaml
    name: settings

- name: Extract tags from trust + untrust variables
  set_fact:
    trust_tag_filter: "{{ trust.split(':')[0] }}"
    untrust_tag_filter: "{{ untrust.split(':')[0] }}"

- name: Routers configuration, filter "{{ filter }}", with trust tag filter "{{ trust_tag_filter }}", and untrust tag filter "{{ untrust_tag_filter }}"
  iosxr_command:
    commands:
    - show run formal object-group network ipv4 | u egrep {{ filter }}
    - show run ipv4 access-list acl_trust_in | u egrep {{ filter }}
    - show run formal interface | u egrep "BVI{{ trust_tag_filter }}"
    - show run formal interface | u egrep "BVI{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether21.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether21.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether22.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether22.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether23.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether23.{{ untrust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether24.{{ trust_tag_filter }}"
    - show run formal interface | u egrep "Bundle-Ether24.{{ untrust_tag_filter }}"
    - show run l2vpn bridge group TRUST bridge-domain VLAN{{ trust_tag_filter }}
    - show run l2vpn bridge group UNTRUST bridge-domain VLAN{{ untrust_tag_filter }}
    - show run router static address-family ipv4 unicast | utility egrep 'router\ static|family|{{settings.lan_subnet_prefix}}{{filter}}|10.30.{{filter}}'
    - show evpn evi | u egrep 'VPN-ID|{{ trust_tag_filter }}|{{ untrust_tag_filter }}'
