Multi-platform builds append a
-t
argument for each alias to thedockerBuildOptions
, but thepublishTask
function was ALWAYS iterating over the aliases even if it was a multi-platform build.sbt-native-packager/src/main/scala/com/typesafe/sbt/packager/docker/DockerPlugin.scala
Lines 157 to 159 in 7c68859
The consequence was attempts to buildx and push the tags multiple times. In some environments this leads to build failures because you can't push the same tag twice.
This change simply does not iterate over the aliases for multiplatform builds.
Note: using
dockerUpdateLatest := true
counts as having multiple aliases, which is how I encountered this bug.
