2023-02-23 14:46:13.966 [DefaultDispatcher-worker-2] INFO ktor.application - HTTP server shutdown!

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)

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

You're calling it outside of the

resourceScope

so the

resourceScope

and thus the

server

terminates.
