Scala SBT 设置 dockerRepository "Repository for publishing is not specified"

Question

我正在尝试使用以下命令将 scala 构建发布到 docker 注册表:

./sbt "; set dockerRepository := Some(\"registryname/project\"); docker:publish"

我正在指定 dockerRepository 但在运行命令时它会抛出以下错误:

[error] You cannot push a "root" repository. Please rename your repository to <user>/<repo> (ex: <user>/example)
java.lang.RuntimeException: Repository for publishing is not specified.
[error] (all/*:publishConfiguration) Repository for publishing is not specified.
[error] (server/docker:publish) Nonzero exit value: 1
[error] (config/*:publishConfiguration) Repository for publishing is not specified.
[error] Total time: 63 s, completed 01/09/2015 10:48:04 AM

当我查看我的本地 docker registry 时，我可以看到它编译了 docker 镜像但没有为 docker registry 名称添加前缀:

docker images

REPOSITORY                                     TAG                                           IMAGE ID            CREATED             VIRTUAL SIZE
example                                        0.0.1    SNAPSHOT   a6eb8942aa9f        8 minutes ago       1.136 GB

所以它似乎没有接受我在命令中设置的 dockerRepository 变量，这也在构建日志中:

[15:33:01][Step 4/5] [info] Set current project to example (in build file:/build/)

来自 Alex Laverty 的评论:

在build.sbt中:

ThisBuild 中的 dockerRepository := Some("docker.io")

或在带有子模块的项目中:

lazy val server = (project in file("server"))
  .settings(dockerRepository := Some("docker.io"),
            dockerUsername := Some("pame"),
            ...)

然后:

sbt docker:publish
