Does docker:publishLocal support multiple modules?

[dluc]

In a project with multiple modules, e.g.
...
/build.sbt
/somelibrary/main/src
/service1/main/src
/service2/main/src
/service3/main/src
...

is it possible to package each service independently, e.g. in this case to 3 different docker images? If so what is the command (from command prompt)?

I'd typically run sbt docker:publishLocal but I think the command is different in this case?

Thanks

Sorry for replying this late 😢 . I must have missed this issue.

When you package your projects in sub-modules ( what your example looks like ) then you already get three docker images. E.g. if you have a build.sbt like this

lazy val root = project(".").aggregate(service1, service2, service3)
lazy val service1= project("service1")
    .enablePlugins(JavaAppPackaging)
    .settings(name := "service1")
lazy val service2= project("service2")
    .enablePlugins(JavaAppPackaging)
    .settings(name := "service2")
lazy val service3= project("service3")
    .enablePlugins(JavaAppPackaging)
    .settings(name := "service3")

If you call sbt docker:publishLocal, all three will be published as separate docker images.

@muuki88 is there a way to build an image for one specific sub-project and not all of them at once?

[muuki88]

Sure. Either you configure the native packager plugins only on the sub modules you want or you can all the publish/package command scoped to a submodule mySubmodule / Docker / publish

@muuki88 it turns out that DockerPlugin was activated for most sub-projects as a result of activating the JavaAgentPackaging plugin (which is brought by JavaAgent). This caused those sub-projects to have docker related tasks running. We can easily confirm this with a sub-project using .enablePlugins(com.lightbend.sbt.javaagent.JavaAgent).

How do you suggest calling the publish/package command scoped to a submodule mySubmodule / Docker / publish?

[muuki88]

What sbt command is triggering the docker related tasks?

Maybe you can try disablePlugins(...) on the sub modules you don't want docker tasks running.

I tried publish and stage, they both seem to have DockerPlugin running. I think I will just override them and use a flag setting to invoke docker tasks if it is set to true.
