我制作了一个循环播放 .yaml 文件并向接口添加描述的 Ansible 剧本。问题是在 Ansible 提交每个 set 命令后，等待提交然后配置下一个接口。如果我在一个有 10 个成员的 VC 上运行它，它将永远存在。任何人都知道如何在所有更改完成后才提交剧本？

---
- name: Change configuration using junos_config module
  hosts: test
  connection: local
  gather_facts: no
  tasks:
  - include_vars: /home/ansible/interfaces.yaml
  - name: Change description on interfaces based on a list of variable
    junos_config:
      lines:
        - "set interfaces {{ item.name }} description \"{{ item.description }}\""
     comment: "Update description of interface {{ item.name }}"
   with_items: "{{ interfaces }}"
   register: result

  - debug: var=result

我改变了现在看起来像这样的剧本：

---
- name: Change configuration using junos_config module
  hosts: test
  connection: local
  gather_facts: no
  tasks:
  - include_vars: /home/ansible/playbook-core/interfaces.yaml
  - name: Change description on interfaces based on a list of variable
    junos_config:
      lines:
        - "{{ lines_template }}"
        - "set interfaces {{ item.name }} description \"{{ item.description }}\""
      comment: "Update description of port"
    vars:
      lines_template: "[ {% for interface in interfaces %}'set interfaces {{ item.name }} description \"{{ item.description }}\"',{% endfor %} ]"
    with_items: "{{ interfaces }}"
    register: result

  - debug: var=result

当我运行它时，我得到一个错误：

将循环逻辑移至 Jinja2 模板：

- name: Change description on interfaces based on a list of variable
  junos_config:
    lines: "{{ lines_template }}"
      - "set interfaces {{ item.name }} description \"{{ item.description }}\""
    comment: "Update description of interfaces"
  vars:
    lines_template: "[ {% for interface in interfaces %}'set interfaces {{ interface.name }} description \"{{ interface.description }}\"',{% endfor %} ]"

最后一个,可以跳过，但似乎 Ansible 弥补了这一点。

上面的代码没有用瞻博网络测试，但它应该产生你想要的。
