【问题描述】：
我正在尝试将这个很棒的 Scala 应用程序部署为 Docker 容器。 https://github.com/OlegIlyenko/graphql-toolbox
它使用 sbt 构建系统。我尝试使用这个 Dockerfile 在容器中运行 sbt。 https://gist.github.com/rzachariah/77eb927f650347ef06d0009dc220cd4a
容器构建并启动，然后立即退出。
我猜sbt run 是一个交互式进程——而不是一个守护进程。在容器中sbt run 可能是个坏主意。
我开始研究 sbt-assembly 来创建一个我可以执行的胖 jar。 https://github.com/sbt/sbt-assembly
我在执行sbt assembly 时遇到一些错误。

我想我需要定义一个合并策略，但我对如何做到这一点有点困惑。任何指针？我完全是 Scala 新手。
【问题讨论】：
-
我认为使用 sbt 运行生产应用程序真的是个坏主意。我用那个插件打包我的应用程序：scala-sbt.org/sbt-native-packager。打包它，而不仅仅是将那个胖应用程序添加到 docker 映像中
-
这里有很多打包选项。 scala-sbt.org/sbt-native-packager 这是一个好的包装选择吗？ github.com/sbt/sbt-assembly 关于如何将合并策略添加到看起来像这样的构建的任何提示？ github.com/OlegIlyenko/graphql-toolbox/blob/master/build.sbt 谢谢！
