ubuntu-essential: 最小構成の Ubuntu Docker Image

Posted at

Docker Image でサイズの小さい Ubuntu と言えば公式の

https://hub.docker.com/_/ubuntu-debootstrap/ (87MB)

ですが、残念ながら DEPRECATED になってしまっています。
さて、どうしたものか、自分で Build しようかと調べていたら、公式では無いもののさらに小さいイメージを発見しました。

https://hub.docker.com/r/textlab/ubuntu-essential/ (61MB)

比較しますと、

+--------------+----------------------------------+----------+---------------------+
|      ID      |            NAME:TAGS             | SIZE(MB) |     CREATED AT      |
+--------------+----------------------------------+----------+---------------------+
| 6cc0fc2a5ee3 | ubuntu:14.04.3                   |  187.900 | 2016-01-20 08:31:24 |
| 8e0aa5f79abe | ubuntu-debootstrap:14.04.3       |   87.066 | 2015-10-14 12:34:58 |
| ceec11e38a60 | textlab/ubuntu-essential:latest  |   60.831 | 2014-12-09 05:15:37 |
+--------------+----------------------------------+----------+---------------------+

ちょっと残念なのは作成されたのがかなり古いということ。

こちらのスクリプトで作られているようなので、最新の ubuntu:14.04 をベースに自分で Build してみました。

これで最新の状態で最小構成の Ubuntu Image が出来ました〜
ダウンロードも速いし、必要なパッケージのみ追加すればいいので、これをベースにすれば小さいイメージになります。
