Started using SuspendApp and suspend-app-ktor, and I'm getting this:

right after Ktor was already ready to receive connections! Why is it closing down like that?

You're probably immediately terminating the application, you need to awaitCancellation of the SuspendApp.
https://github.com/nomisRev/ktor-arrow-example/blob/efb93311e4a0d2db47ecb1c134e0ec0f922d7d2d/src/main/kotlin/io/github/nomisrev/main.kt#L21

Similarly to how you would otherwise call start(wait = true).

[dave08]

fun main() = SuspendApp {
    resourceScope {
        val appConfigs = getAppConfig {
            addResourceSource("/application.yml")
            addResourceSource("/application-dev.yml", true)
            addEnvironmentSource()
        }

        val appResources = appResources(appConfigs)

        server(
            Netty, port = 8080, host = "0.0.0.0",
            module = AppComponent::class.create(appResources, appConfigs).appModule
        )
    }
    awaitCancellation()
}

That's what I have

[simon.vergauwen]

You're calling it outside of the resourceScope so the resourceScope and thus the server terminates.

Thanks!
