【问题描述】：

我正在尝试使用 sbt-native-packager 和以下 build.sbt 构建 Docker 映像（尝试将映像发布到本地存储库）

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 和打包器版本

$ cat project/plugins.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.0")
$ cat project/build.properties 
sbt.version=0.13.18

当我尝试运行打包程序时

$ 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

它无法识别 dockerAliases 不知道为什么，因为它是发布设置的一部分。设置 Docker 注册表的正确方法是什么？？

【解决方案1】：

你的 sbt-native-packager 版本已经过时了，就像你的 sbt 版本一样。该版本中不存在该 SettingKey。

比较：sbt-native-packager 1.0 与 sbt-native-packager 1.7.4
