yumパッケージの存在確認

More than 3 years have passed since last update.

ansibleでサーバの設定をモクモクとやってます。
そんな中、yumパッケージがあったら(なかったら)〜を行うような事があったけど
なかなかいいやり方がなかったので調べてみたところ、以下のやり方に落ち着いたのでメモ。

# {{ package }}はパッケージ名
# mariadb-libs.x86_64とか

- name: check if "{{ package }}" is installed
  yum:
    list="{{ package }}"
  register: pkg

- name: install "{{ package }}" if exist
  yum:
    name: "{{ package }}"
    state: latest
  when: pkg.results|selectattr("yumstate", "match", "installed")|list|length != 0

参考
