docker packager ignores settings

[raam86]

I have the following build.sbt (some settings removed for brevity)

lazy val overrider = project.in( file("modules/override-flow"))
  .dependsOn(consumer,adapters,monitor,flows)
  .aggregate(consumer, adapters,monitor,flows)
  .enablePlugins(JavaAppPackaging)
  .enablePlugins(DockerPlugin)
  .settings(
    NativePackagerKeys.dockerExposedVolumes := Seq("/opt/docker/logs","/opt/docker/config"),
    NativePackagerKeys.dockerExposedPorts := Seq(8080),
    NativePackagerKeys.dockerBaseImage := "java:8-jre"
)


lazy val root = project.in( file(".") )
  .dependsOn(consumer,adapters,monitor,flows)
  .aggregate(consumer, adapters,monitor,flows)
  .enablePlugins(JavaAppPackaging)
  .enablePlugins(DockerPlugin)

dockerExposedVolumes := Seq("/opt/docker/logs","/opt/docker/config")

dockerExposedPorts := Seq(9999)

dockerBaseImage := "java:8-jre"

root project is packaged as expected but overrider project will package with default settings.
No errors and everything finishes "successfully".

Am I missing something?

Hm. So

lazy val overrider = project.in( file("modules/override-flow"))
  .dependsOn(consumer,adapters,monitor,flows)
  .aggregate(consumer, adapters,monitor,flows)
  .enablePlugins(JavaAppPackaging)
  .enablePlugins(DockerPlugin)
  .settings(
    // this should apply these settings correctly to 'overrider'
    dockerExposedVolumes := Seq("/opt/docker/logs","/opt/docker/config"),
    dockerExposedPorts := Seq(8080),
    dockerBaseImage := "java:8-jre"
)

When you run sbt override/docker:publishLocal then the correct docker image should be created.
You can check these settings with

sbt
> project overrider
> show dockerExposedVolumes
> show ... // other settings

The other settings you apply directly in your build.sbt. Actually I'm not sure if these
get overridden, when the AutoPlugins get applied on the project.

dockerExposedVolumes := Seq("/opt/docker/logs","/opt/docker/config")
dockerExposedPorts := Seq(9999)
dockerBaseImage := "java:8-jre"

Moving the specific settings to the correct project did the trick:

lazy val root = project.in( file(".") )
  .dependsOn(consumer, adapters, monitor, flows)
  .aggregate(consumer, adapters, monitor, flows)
  .enablePlugins(JavaAppPackaging)
  .enablePlugins(DockerPlugin)
  .settings(dockerExposedVolumes := Seq("/opt/docker/logs","/opt/docker/config"),
  dockerExposedPorts := Seq(9999),
  dockerBaseImage := "java:8-jre")

After applying the changes the image is created correctly.

Can not recreate former conditions even after cache cleaning.
