Ansible + Cisco 幂等性 [英] Ansible + Cisco idempotence

问题描述

所以我正在使用 Ansible 进行一些测试来管理 Cisco 设备(在本例中特别是 3750).我可以毫无问题地添加我的 VLAN 和环回.

So I'm doing some testing with Ansible to manage Cisco devices (specifically a 3750 in this case). I'm able to add my VLAN's and Loopbacks with no issue.

当存在环回或 VLAN 时，只是试图让 Ansible 停止在任务中注册更改.

Just trying to get Ansible to stop registering a change in the task when the Loopback or VLAN exists.

现在我的剧本是这样的:

Right now my play looks like this:

    - name: Set the IP for Loop 0
  ios_config:
    provider: "{{ connection }}"
    lines:
      - description AnsibleLoop0
      - ip address 8.8.8.8 255.255.255.0
    before:
      - interface Loopback0
    match: exact

任何时候运行这个任务，Ansible 都会像更改一样注册它:

Anytime this task is run, Ansible registers it like a change:

已更改:[switch] =>{"changed": true, "updates": ["interface Loopback0", "description AnsibleLoop0", "ip address 8.8.8.8 255.255.255.0"], "warnings": []}

我尝试了不同的 match 类型(line，exact)，但无济于事.也许我在这里弄错了.

I've tried different match types (line, exact) to no avail. Maybe I'm getting something wrong here.

我想，如果我让剧本插入这些行，就像它们在 show run 中的显示方式一样，它就不会将其注册为更改?

I thought that if I had the play insert the lines exactly like how they would show up in a show run it wouldnt register it as a change?

这里的任何帮助将不胜感激！

Any help here would be appreciated!

推荐答案

您可能遇到此问题:

您是否每次都使用剧本中的 save: "yes" 将配置更改保存到 Cisco 设备中?我遇到了同样的问题，每次运行剧本时我都保存配置.设置no 只是为了测试，在第一次运行报告 changed=True 后，Ansible 将报告 changed=False 连续运行.

Are you saving the configuration changes each time to the Cisco device using save: "yes" in your playbook? I had the same problem and I was saving the config each time the playbook ran. Setting that to no just to test, after the first run reports changed=True sequential runs would report back changed=False by Ansible.
