サーバーの情報を利用する (GATHERING FACTS)

playbook を実行するとまずサーバの情報を収集します。 実行時に GATHERING FACTS を表示されている部分です。次のような情報が収集され、これを task の中で利用することができます

templates で IP address を埋める場合には {{ ansible_eth0["ipv4"]["address"] }} と書けます。 {{ ansible_eth0.ipv4.address }} でも可。 {{ ansible_processor_count * 5 }} として計算結果を利用することもできます。次に説明する条件付き実行の条件としても使えます。

この収集処理にはそこそこ時間がかかるため、このデータを利用しない場合は playbook で gather_facts: no と指定することで省略することが可能です。
