ロール内でディレクティブを利用して変数やターゲットノードをコントロールする
はじめに
ロールやタスクレベルで変数やターゲットノードをコントロールしたい場合、ディレクティブで結構柔軟に対応できます。下記に、Play、Role、Block、Taskに利用可能なディレクティブの一覧が記載されています。
以下、簡単な検証結果です。
Playbook
- ロールの呼び出し元
hostsはCisco DevNet SandboxのCSRを指定しています。
--- - hosts: csr gather_facts: false collections: - cisco.ios tasks: - name: import debug role import_role: name: debug
