ansible 2.4 でこっそり追加された inventory file の情報をいい感じに整形して出力してくれるコマンド
通常の ansible-* コマンドと同様に -i で inventory file 指定や、 -l で limit 指定が可能
output形式を yaml にしたい場合は -y をつける
enginyoyen/ansible-best-practises を使って試す
--graph
group と host の紐付けを tree 表示する。children に指定した入れ子も解決してくれる
ansible-best-practises> ansible-inventory -i production.ini --graph
@all:
|--@postgresql:
| |--postgresql000.prod.example.com
|--@ungrouped:
|--@webservers:
| |--webserver000.prod.example.com
| |--webserver001.prod.example.com
| |--webserver002.prod.example.com
| |--webserver003.prod.example.com
| |--webserver004.prod.example.com
--host HOSTNAME
単一の host を指定し、group_vars, host_vars を集めて変数を表示する
ansible-best-practises> ansible-inventory -i production.ini --host webserver000.prod.example.com
