abstract class AkkaServerStreamlet extends AkkaStreamlet with Server
An AkkaStreamlet that can listen on a port.
Using this trait instead of the AkkaStreamlet ensures that the streamlet will get an endpoint in Kubernetes.
This trait mixes on the Server
trait which is required for using a ServerStreamletLogic.
The ServerStreamletLogic provides a containerPort
and a getContainerPort()
method.
It returns the TCP port that is opened on the container. Listen on all interfaces ("0.0.0.0") and use the port
returned by containerPort
to start a TCP server that will be exposed by an endpoint in Kubernetes.

Initialize the streamlet from the config. In some cases (e.g. the tests) we may pass a context directly to be used instead of building it from the config.
