Dockerコンテナとしてのscalaアプリケーションのデプロイ

Question

私はこの素晴らしいScalaアプリケーションをDockerコンテナとしてデプロイしようとしています。 https://github.com/OlegIlyenko/graphql-toolbox

これはsbtビルドシステムを使用しています。このDockerfileを使ってコンテナ内でsbtを実行しようとしました。 https://gist.github.com/rzachariah/77eb927f650347ef06d0009dc220cd4a

コンテナが構築され、開始されますが、すぐに終了します。

私はsbt runがデーモンプロセスではなく対話プロセスであると思います。コンテナ内のsbt runにはおそらく悪い考えです。

私はちょうど実行することができる太った瓶を作成するためにsbtアセンブリを調べ始めました。 https://github.com/sbt/sbt-assembly

私はsbt assemblyを入力するとエラーが発生します。

私は、マージ戦略を定義する必要があると思うが、私はそれを行う方法に少し困惑しています。すべてのポインタ？私はScala初心者です。

Answer 1

私は、私のscalaアプリケーションがプレーフレームワークを使用し、ネイティブパッケージャが組み込まれているので、私のアプリケーションをコンテナにパッケージングするのは簡単です！
