[要望]Dockerコンテナ化

[yuhkan]

お世話になっております。 掲題のとおりなのですが、スクリプト、アプリ等をDockerのコンテナ化できないでしょうか？

実際、そのような試みを行っている方もいて、その方の環境では動作しているようなのですが、 私の環境では構築に失敗し、手動でのインストールも試みましたが、やはりうまくいかない状態です。 (私の知識、理解不足によるところが大きいと思うのですが……) 参考：https://azriton.github.io/2017/04/14/CrystalSignalPi-on-Docker/

Raspberry piを利用した様々な実験を行いつつ、シグナル機能は並立させたいというとき、コンテナ化されているというのは非常に魅力的で(なんどもfullinstallしなくて良い！)、 公式の機能としてサポートされていれば、非常に利用しやすくなるのではないかと思います。

ちなみに、Raspbian/jessieのイメージに、現行のインストール方法でfullinstallを行った場合、最終段において以下のようなエラーとなります。 2017-11-25 17:39:13 (2.22 MB/s) - ‘/var/www/html/js/bootstrap-slider-9.5.1.min.js’ saved [35789/35789]

yuhkanさん、こんにちは。 ご要望ありがとうございます。Dockerの導入を検討します。

Failed to get D-Bus connection: Unknown error -1

上記エラーメッセージに関しては、Docker内でインストールを行った際に出たエラー、という理解でいいでしょうか？もしそうだとすると、Dockerコンテナの中ではPID1としてinitが動いてないことが原因だと考えられます。

initをPID1で起動するように「--init」オプションをつけて起動させてからinstall.shを実行しましたが、yuhkanさんと同じエラーがでてしまいました。

apache2をリロードした後に「Failed to get D-Bus connection: Unknown error -1」とエラーが出ていますが、解決方法がまだ見つかりません。

Dockerの導入を期待しています。 よろしくお願いします。
