AnsibleでCisco IOSの情報収集 - ios_commands

#背景
[AnsibleでCisco IOSの情報収集 - ios_facts](http://qiita.com/kikuta1978/items/f38298bd357f7a315819) と [AnsibleでCisco IOSの情報収集 - snmp_facts](http://qiita.com/kikuta1978/items/f0c0c408568ce8631167)の続編。今回は[ios_command](http://docs.ansible.com/ansible/ios_command_module.html)の記録。[ios_config](http://docs.ansible.com/ansible/ios_config_module.html)はコンフィグモードでの設定がメインであるのに対して、こちらは主にshowコマンド実行とその結果の処理・活用がメイン。

基本的にコマンドの連打と処理は、力技感が否めませんが、Ansibleモジュールを使うとリターンがJSONなので処理・再利用をしやすい。Netconf/YANGやRestconfの実装も進んでいるが、特にサポートが後回しになるローエンドやバージョンアップできない古い装置・ソフトウェアなども等しく使えるのは利点である。ただし、中身（データモデル）は個々の環境に合わせてパースする必要がある（*コマンドの宿命）。
*ただし、コマンド出力を共通データモデルに合わせる取り組みもあるにはある

※ansible.cfgやinventoryの設定は省略。
※環境は[こちら](http://qiita.com/kikuta1978/items/f38298bd357f7a315819)と同じなので省略。

#Playbookサンプル - ios_command

- gather_facts: no のサンプルが多いが、yesにするとシステム変数（ansible_date_timeなど）が使える（この例ではファイル名に利用）
- ファイル名にansible_net_hostnameを使いたいので、ios_factsも実行しておく
- ios_factsのサブセットは、軽そうなinterfacesに（all, hardware, config, and interfacesから選択）
- 使いたいansible_net_hostnameは、どのサブセットでもリターンする（よって処理は軽い方が良いと判断）
- catalyst3850や3650のように、shellのリターンが遅い機種があるため、timeout: 30 を追加（これがないと、Failする場合がある）

```yaml:ios_command.yml
---
- hosts: ios
  gather_facts: yes 
  connection: local

  tasks:
    - name: ios_facts to get returned values
      ios_facts:
        gather_subset:
          - interfaces
        provider: "{{ cli }}"

    - name: run multiple IOS exec commands
      ios_command:
        commands:
          - show version
          - show run brief
          - show arp
          - show ip route
        provider: "{{ cli }}"
        timeout: 30
      register: result

    - copy:
        content: "{{ result }}"
        dest: "file/{{ ansible_date_time.year }}{{ ansible_date_time.month }}{{ ansible_date_time.day }}{{ ansible_date_time.hour }}{{ ansible_date_time.minute }}{{ ansible_date_time.second }}_{{ ansible_net_hostname }}_VerRunArpRoute.txt"
  
  vars:
    cli:
      host: "{{ inventory_hostname }}"
      authorize: yes
      username: "{{ ansible_ssh_user }}"
      password: "{{ ansible_ssh_pass }}"
      auth_pass: "{{ enable_pass }}"
```

#実行例
4つのshowコマンドを実行し、ファイルに保存。ファイル名は、日付＋ホスト名＋テキストで重複しないように。見ながら実行するときはVerboseモード（-vvvvとか）にすると細かく確認できる。

```bash:ios_command.yml
[vagrant@localhost ansible]$ ls file/
[vagrant@localhost ansible]$ 
[vagrant@localhost ansible]$ ansible-playbook ios_command.yml

#ファイル確認
ファイルの中身はJSONであり、以下のとおりキーに対する値がリスト形式。特に、stdout_linesに対する値が、行ごとにリストになっているため、同じ力技でも比較的、欲しい部分が取り出しやすい。（以下のログはjqで整形）

```json:20170323083141_CSR-2_VerRunArpRoute.txt

#フィルタ例
jqでフィルタする例。実際には、pythonスクリプトでファイルを読み込んで楽に処理するイメージ。

##コンフィグレーションからbanner部分を取り出す

```bash:20170323083141_CSR-2_VerRunArpRoute.txt
[vagrant@localhost ansible]$ cat file/20170323083141_CSR-2_VerRunArpRoute.txt | jq .stdout_lines[1][214]
"banner motd ^CHello Ansible!^C"
[vagrant@localhost ansible]$
```

##ARPテーブルを取り出す
この中身もリストになっているので、色々処理しやすい！ルーティングテーブルとか、フローキャッシュテーブルとか.. これは便利な気がする。

```bash:20170323083141_CSR-2_VerRunArpRoute.txt
[vagrant@localhost ansible]$ cat file/20170323083141_CSR-2_VerRunArpRoute.txt | jq .stdout_lines[2]
