Why? I mean, at least with gradle you can see the source code and kdocs for any symbol just by ctrl/cmd+click

I can go as far as EmbeddedServer.kt, but can't go into TEngine...

Also on start() there's no docs I see

Let me check

I see. That’s because the documentation is part of the interface that NettyApplicationEngine implements. If you are using the interface it works.

Going to see if we can improve this

Thanks! btw, if I do the setup of start(false), start(true), if the second one fails for any reason, the first one will also go down? Would there be a fault tolerant way of keeping any healthy one alive?

Untested, but maybe something like this?

fun main(args: Array<String>) {
    val engineApi = embeddedServer(Netty, port = 8080, module = Application::apiModule)
    val engineInternal = embeddedServer(Netty, port = 9090, module = Application::internalModule)

    val engineApiStopDeferred = CompletableDeferred<Unit>()
    val engineInternalStopDeferred = CompletableDeferred<Unit>()

    engineApi.environment.monitor.subscribe(ApplicationStopped) { engineApiStopDeferred.complete(Unit) }
    engineInternal.environment.monitor.subscribe(ApplicationStopped) { engineInternalStopDeferred.complete(Unit)  }

    try { engineApi.start(wait = false) } catch (e: Throwable) { e.printStackTrace() }
    try { engineInternal.start(wait = false) } catch (e: Throwable) { e.printStackTrace() }

    runBlocking {
        engineApiStopDeferred.await()
        engineInternalStopDeferred.await()
    }
}

Interesting... this might be a nice solution also regarding my problem w/ Docker.. but I'd just have to implement the last part a bit differently... thanks!

The only problem is where to put the health check... 😞
