sbt-release with docker plugin step

[mhamrah]

I'm trying to add a ReleaseStep using sbt-release that publishes a docker image. I've overwritten the current release process like so:

ReleaseKeys.releaseProcess := Seq[ReleaseStep](
  releaseTask(publishLocal in Docker)
)

but nothing happens when I run release (I've tried reloading sbt). When running

docker:publishLocal

everything works fine, I thought this translated to a TaskKey of publishLocal in Docker for sbt-release. I figure I'm missing something obvious. I glanced at this code, and it appears that docker.Keys.publishLocal is set to sbt.publishLocal, and I can't figure out how the docker setting for publish local maps to a task.

Thanks,

Mike

FYI sbt-native-packager 0.8.0.

I'll try to reproduce this with a small example. IMHO it sounds like some interaction problem with sbt-release, however I haven't tried it with sbt-np yet.

@muuki88 I hacked around with it, and stumbled upon a solution but I don't know why it works. I had to add "in ref" to the release step:

lazy val dockerRelease: ReleaseStep = { st: State =>
  val extracted = Project.extract(st)
  val ref = extracted.get(thisProjectRef)
  extracted.runAggregated(publish in Docker in ref, st)
}

I copied code from sbt-release which had something similar.

Thanks for sharing @mhamrah If you have time it would be awesome to provide a small example for this in the docs (with a minimal build.sbt) showing this. There is an advanced topics section in src/sphinx/topics where this would fit perfectly.

@jsuereth you have any clue why @mhamrah 's solution works?

@muuki88 I'm always happy to add documentation!

That's awesome to hear :) Looking forward to your pull request

Here is a more elegant way with releaseStepTask:

releaseProcess := Seq(
  checkSnapshotDependencies,
  inquireVersions,
  runTest,
  ReleaseStep(releaseStepTask(publish in Docker)))
