Repository for publishing is not specified in multi-modules project with docker sbt

Question

I am trying to deploy a multi-modules project using an sbt-docker plugin. I want to create separate containers for api and app modules and to skip other modules. However, every time I run docker: publish I get such an error:

[error] (api/*:publishConfiguration) Repository for publishing is not specified.
[error] (app/*:publishConfiguration) Repository for publishing is not specified.

Here is my build.sbt file:

import sbt.Keys.publishTo

name := "project-name"

val globalSettings = Seq[SettingsDefinition](
  version := "1.0",
  scalaVersion := "2.12.4"
)

enablePlugins(DockerPlugin)

//.. other modules

val app = Project("app", file("app"))
  .enablePlugins(DockerPlugin)
  .dependsOn(repositories)
  .settings(globalSettings: _*)
  .settings(
    libraryDependencies ++= Seq(
      "com.typesafe.akka" %% "akka-http" % "10.0.11",
      "com.typesafe.akka" %% "akka-http-testkit" % "10.0.11" % Test,
      "de.heikoseeberger" %% "akka-http-circe" % "1.18.0",
      "net.ruippeixotog" %% "scala-scraper" % "2.1.0"
    ),
    resolvers += Resolver.bintrayRepo("hseeberger", "maven")
  )
  .settings(assemblyJarName in assembly := "app.jar")
  .settings(dockerfile in docker := {
    val artifact: File = assembly.value
    val artifactTargetPath = s"/app/${artifact.name}"

    new Dockerfile {
      from("java")
      add(artifact, artifactTargetPath)
      entryPoint("java", "-jar", artifactTargetPath)
    }
  },
    imageNames in docker := Seq(ImageName(s"name/dru-app"))
  )

val api = Project("api", file("api"))
  .enablePlugins(DockerPlugin)
  .dependsOn(app)
  .settings(globalSettings: _*)
  .settings(
    libraryDependencies ++= Seq(
      "com.typesafe.akka" %% "akka-http" % "10.0.11",
      "com.typesafe.akka" %% "akka-http-testkit" % "10.0.11" % Test,
      "de.heikoseeberger" %% "akka-http-circe" % "1.18.0",
      "net.ruippeixotog" %% "scala-scraper" % "2.1.0"

    ),
    resolvers += Resolver.bintrayRepo("hseeberger", "maven")
  )
  .settings(assemblyJarName in assembly := "api.jar")
  .settings(dockerfile in docker := {
    val artifact: File = assembly.value
    val artifactTargetPath = s"/api/${artifact.name}"
    publishTo := Some(Resolver.file("Unused transient repository", file("https://hub.docker.com/r/name/dru-api")))

    new Dockerfile {
      from("java")
      add(artifact, artifactTargetPath)
      entryPoint("java", "-jar", artifactTargetPath)
    }
  },
    imageNames in docker := Seq(ImageName(s"name/dru-api"))
  )


val root = Project("DRU-W3-FP-1-Toloka-Parser", file("."))
  .aggregate(app, api)
  .settings(
    publish := {},
    publishLocal := {},
    publishArtifact := false,
    publishTo := Some(Resolver.file("Unused transient repository", file("target/unusedrepo")))
  )

I would be very grateful for any advice on how to fix my build.sbt file to publish it to docker hub!

My guess would be that you have two different problems for your subprojects app and api:

1) In app, it seems like you're missing a publishTo setting. I would expect to have one, as per official SBT docs.

2) In api, there is one publishTo but it is defined within the block .settings(dockerfile in docker := {...}) so the value is not returned / assigned to your sub-project's setting. Try extracting it from there and setting up explicitly e.g. .settings(publishTo := Some(Resolver.file("Unused transient repository"...))) like as you do for the root project.

Hope that helps!
