执行playbook后提交所有更改

Question

我制作了一本Ansible游戏书，它循环遍历.yaml文件，并为界面添加说明。问题是在每个设置命令Ansible提交之后，等待提交然后配置下一个接口。如果我在拥有10个成员的VC上运行它，它将永远需要。任何人都知道如何在完成所有更改后才能使Playbook提交？

- 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，我收到一个错误：

vvv. The error was: TypeError: sequence item 0: expected string, list found

将循环逻辑移动到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 %} ]"

可以跳过最后的,，但似乎Ansible弥补了这一点。

上面的代码没有使用Juniper测试，但它应该产生你想要的。
