Ubuntu(WSL)にansibleインストール & 作業準備
Contents
概要
- 今回は、備忘録としてansibleインストール & セットアップ方法をまとめます。前半は、Ubuntu(WSL)にansibleをインストールしています。後半は、ansible からAWS のEC2 に対してplaybook を実行する方法を記載しています。
- 背景として、playgook を利用した作業があり、手元にansible の環境がなかったためセットアップします。前提として、Windows 10 + WSL2 上のUbuntu を利用します。
Ubuntu(WSL)にansibleインストール手順
パッケージのアップデート
- 事前作業として、apt-get updateでパッケージリストを更新します。

AWS EC2 にplaybook を実行する
inventory とplaybook の準備
- inventory を準備します。inventory は、ターゲットノードを管理するためのファイルです。ansible_host にserver1 で使用するIPアドレスを定義します。
- “[ ]"で囲み、グループの定義も可能です。グループに対して、ユーザー名、ssh秘密鍵を指定しています。
$ cat test01_inventory.ini

server1 ansible_host=11.11.11.11
[server:vars]
ansible_user=ec2-user
ansible_ssh_private_key_file=./niikawa-testkey.pem- playbook を準備します。playbook は、タスクを定義する YAMLファイルです。今回のタスクは、/tmp にtest.txt を作成します。
$ cat test_book.yml
