Repository for publishing is not specified.

This is regarding the shopping-cart-scala app.

I get the following error when I try to publish the docker images to docker hub:

[error] java.lang.RuntimeException: Repository for publishing is not specified.
[error] 	at scala.sys.package$.error(package.scala:26)
[error] 	at sbt.Classpaths$.$anonfun$getPublishTo$1(Defaults.scala:2644)
[error] 	at scala.Option.getOrElse(Option.scala:121)
[error] 	at sbt.Classpaths$.getPublishTo(Defaults.scala:2644)
[error] 	at sbt.Classpaths$.$anonfun$ivyBaseSettings$48(Defaults.scala:2089)
[error] 	at scala.Function1.$anonfun$compose$1(Function1.scala:44)

I pass docker username and respository as an argument to sbt like so:

sbt -Ddocker.username=codingkapoor -Ddocker.registry=index.docker.io

Images do get pushed but I still the error when I try to publish docker:publish.

Please suggest. TIA.
