在Play JPA项目中使用sbt native packager向Docker添加自定义文件夹

我正在做一个JPA+Playframework 2.5.x项目，我把它打包成Docker镜像

我想强制将

conf

文件夹下除一个文件（META-INF/persistence.xml）之外的所有文件添加到docker输出

目前，我已完成以下工作：

mappings in Docker += file("conf/base/application.conf") -> "opt/docker/conf/base/application.conf"
mappings in Docker += file("conf/base/default-client.conf") -> "opt/docker/conf/base/default-client.conf"
mappings in Docker += file("conf/prod/application.conf") -> "opt/docker/conf/prod/application.conf"
mappings in Docker += file("conf/prod/logback.xml") -> "opt/docker/conf/prod/logback.xml"
mappings in Docker += file("conf/stage/application.conf") -> "opt/docker/conf/stage/application.conf"
mappings in Docker += file("conf/stage/logback.xml") -> "opt/docker/conf/stage/logback.xml"
mappings in Docker += file("conf/local/application.conf") -> "opt/docker/conf/local/application.conf"
mappings in Docker += file("conf/local/logback.xml") -> "opt/docker/conf/local/logback.xml"
mappings in Docker += file("conf/routes") -> "opt/docker/conf/routes"
mappings in Docker += file("conf/ValidationMessages.properties") -> "opt/docker/conf/ValidationMessages.properties"

我相信这不是实现这一目标的最佳途径。有谁能推荐更好的选项，以我需要的方式定制Docker输出

我的build.sbt文件：

PlayKeys.externalizeResources := false

lazy val `wp-pw-ng` = (project in file(".")).enablePlugins(PlayJava, JavaAppPackaging)

由于Playframework在build

stage

模式下出现问题，我不得不求助于此解决方案，并且我必须在我的

build.sbt

文件中使用

PlayKeys.externalizeResources:=false

标志。这将从Docker中的

conf

文件夹中删除所有文件。

将

playExternalizeResources:=false

设置为Universal中的

映射，这些映射可用于包括Docker在内的所有目标包格式

您的构建sbt可以用（）结束

您还可以过滤映射以删除不需要的文件，例如

import NativePackagerHelper._
mappings in Universal ++= contentOf("conf").filter(_.2.contains("persistence.xml")

希望有帮助，
Muki
只需在
universal/conf
目录中添加要映射的文件。因此，当您创建docker映像时，文件会添加到
/opt/docker/conf
目录中。
谢谢，我会尝试一下。这不起作用，因为在docker stage文件夹中，我需要文件位于
opt/docker/conf/
下，只需简单地将它们作为
映射添加到docker++=contentOf（“conf”）中即可
将其添加到
target/stage
文件夹下。我需要在
opt/docker/conf/
下重新映射文件，然后使用
目录
而不是
contentOf
和结果映射的映射。就像其他Scala系列一样
import NativePackagerHelper._
mappings in Universal ++= contentOf("conf").filter(_.2.contains("persistence.xml")
