the gradle plugin for the Docker stuff doesn't seem to expose a port and I can't find anything to specify it. am I missing something?

It depends what you're trying to do, but it looks like the runDocker task is hard coded to 8080

[Trevor Stone]

private abstract class RunDockerTask : DefaultTask() {
    @get:Inject
    abstract val execOperations: ExecOperations

    @get:Input
    abstract val fullImageName: Property<String>

    @TaskAction
    fun execute() {
        execOperations.exec {
            it.commandLine("docker", "run", "-p", "8080:8080", fullImageName.get())
        }
    }
}

Otherwise if you need to configure stuff, behind the scenes the docker creation is done using jib which you can configure.

jib {
    container {
        ports = listOf("12345")
    }
}

ah thanks, I will have a look. For now I reverted to a manual dockerfile because neither any hardcoded port showed up as exposed in third parties

[Andreas Scheja]

afaik the port in the dockerfile is just documentation anyway, you can still map any port when running the container

[Trevor Stone]

I think it will expose it if you just run with -P instead of -p with ports defined

[Andreas Scheja]

yeah, but who wants random ports for a server process? 😄
