How to set the Docker Registry with sbt-native-packager - scala

Question

I'm trying to build a Docker image using sbt-native-packager with the following build.sbt (trying to publish the image to a local repository)
val sparkVersion = "2.4.5"
scalaVersion in ThisBuild := "2.12.0"
val sparkLibs = Seq(
"org.apache.spark" %% "spark-core" % sparkVersion,
"org.apache.spark" %% "spark-sql" % sparkVersion
)
// JAR build settings
lazy val commonSettings = Seq(
organization := "dzlab",
version := "0.1",
scalaSource in Compile := baseDirectory.value / "src",
scalaSource in Test := baseDirectory.value / "test",
resourceDirectory in Test := baseDirectory.value / "test" / "resources",
javacOptions ++= Seq(),
scalacOptions ++= Seq(
"-deprecation",
"-feature",
"-language:implicitConversions",
"-language:postfixOps"
),
libraryDependencies ++= sparkLibs
)
// Docker Image build settings
dockerBaseImage := "gcr.io/spark-operator/spark:v" + sparkVersion
lazy val root = (project in file("."))
.enablePlugins(
DockerPlugin,
JavaAppPackaging
)
.settings(
name := "spark-k8s",
commonSettings,
dockerAliases ++= Seq(
dockerAlias.value.withRegistryHost(Some("localhost:5000"))
),
mainClass in (Compile, run) := Some("dzlab.SparkJob")
)
SBT and the packager versions
$ cat project/plugins.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.0")
$ cat project/build.properties
sbt.version=0.13.18
When I try to run the packager
$ sbt docker:publish
[info] Loading global plugins from /Users/dzlab/.sbt/0.13/plugins
[info] Loading project definition from /Users/dzlab/Projects/spark-k8s/project
/Users/dzlab/Projects/spark-k8s/build.sbt:39: error: not found: value dockerAliases
dockerAliases ++= Seq(
^
sbt.compiler.EvalException: Type error in expression
[error] sbt.compiler.EvalException: Type error in expression
[error] Use 'last' for the full log.
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? q
It does not recognize dockerAliases not sure why as it is part of the publishing settings.
What is the proper way to set the Docker registry??

Answer 1

Your sbt-native-packager version is hopelessly outdated, as is your sbt version. That SettingKey doesn't exist in that version.
Compare: sbt-native-packager 1.0 vs. sbt-native-packager 1.7.4
