Ansibleでリポジトリを国内のミラーサーバーに変更する方法メモ

Mirrors : Ubuntu

Ansibleの実装例

Ansibleのreplaceモジュールを使用して、参照リポジトリの書き換えを行います。
以下は例として、jaistのミラーサーバーに書き換えています。

playbook.yml
- hosts: all
  become: yes
  tasks:
    - name: update apache.conf
      replace:
        path: /etc/apt/sources.list
        regexp: 'http://archive.ubuntu.com/ubuntu'
        replace: 'http://ftp.jaist.ac.jp/pub/Linux/ubuntu/'
        backup: yes

この後に、aptでパッケージを取得するtaskを書くと思うんですが、その際に update_cache=yes をつけるようにして下さい。あと、書き換え直後のtaskでは cache_valid_time オプションの指定はつけないほうが良いかもしれないです。

aptでインストールを行う例
    - name: install language-pack-ja
      apt: name={{ item }} update_cache=yes
      with_items:
        - language-pack-ja
